# Save payment details during an in-app payment Save payment details during a payment in your mobile app. # iOS > This is a iOS for when platform is ios and mobile-ui is payment-element. View the full page at https://docs.stripe.com/payments/mobile/save-during-payment?platform=ios&mobile-ui=payment-element. Use the [Payment Intents API](https://docs.stripe.com/api/payment_intents.md) to save payment details from a purchase. There are several use cases: - Charge a customer for an e-commerce order and store the details for future purchases. - Initiate the first payment of a series of recurring payments. - Charge a deposit and store the details to charge the full amount later. > #### Card-present transactions > > Card-present transactions, such as payments through Stripe Terminal, use a different process for saving the payment method. For details, see [the Terminal documentation](https://docs.stripe.com/terminal/features/saving-payment-details/save-after-payment.md). ## Compliance You’re responsible for your compliance with all applicable laws, regulations, and network rules when saving a customer’s payment details for future use, such as displaying a customer’s payment method to them in the checkout flow for a future purchase or charging them when they’re not actively using your website or app. Before saving or charging a customer’s payment mathod, make sure you: - Add terms to your website or app that state how you plan to save payment method details, such as: - The customer’s agreement allowing you to initiate a payment or a series of payments on their behalf for specified transactions. - The anticipated timing and frequency of payments (for example, if the charges are for scheduled installments, subscription payments, or unscheduled top-ups). - How you determine the payment amount. - Your cancellation policy, if the payment method is for a subscription service. - Use a saved payment method for only the purpose stated in your terms. - Collect explicit consent from the customer for this specific use. For example, include a "Save my payment method for future checkbox. - Keep a record of your customer’s written agreement to your terms. ## Set up Stripe [Server-side] [Client-side] First, you need a Stripe account. [Register now](https://dashboard.stripe.com/register). ### Server-side This integration requires endpoints on your server that talk to the Stripe API. Use our official libraries for access to the Stripe API from your server: #### Ruby ```bash # Available as a gem sudo gem install stripe ``` ```ruby # If you use bundler, you can add this line to your Gemfile gem 'stripe' ``` ### Client-side The [Stripe iOS SDK](https://github.com/stripe/stripe-ios) is open source, [fully documented](https://stripe.dev/stripe-ios/index.html), and compatible with apps supporting iOS 13 or above. #### Swift Package Manager To install the SDK, follow these steps: 1. In Xcode, select **File** > **Add Package Dependencies…** and enter `https://github.com/stripe/stripe-ios-spm` as the repository URL. 1. Select the latest version number from our [releases page](https://github.com/stripe/stripe-ios/releases). 1. Add the **StripePaymentSheet** product to the [target of your app](https://developer.apple.com/documentation/swift_packages/adding_package_dependencies_to_your_app). #### CocoaPods 1. If you haven’t already, install the latest version of [CocoaPods](https://guides.cocoapods.org/using/getting-started.html). 1. If you don’t have an existing [Podfile](https://guides.cocoapods.org/syntax/podfile.html), run the following command to create one: ```bash pod init ``` 1. Add this line to your `Podfile`: ```podfile pod 'StripePaymentSheet' ``` 1. Run the following command: ```bash pod install ``` 1. Don’t forget to use the `.xcworkspace` file to open your project in Xcode, instead of the `.xcodeproj` file, from here on out. 1. In the future, to update to the latest version of the SDK, run: ```bash pod update StripePaymentSheet ``` #### Carthage 1. If you haven’t already, install the latest version of [Carthage](https://github.com/Carthage/Carthage#installing-carthage). 1. Add this line to your `Cartfile`: ```cartfile github "stripe/stripe-ios" ``` 1. Follow the [Carthage installation instructions](https://github.com/Carthage/Carthage#if-youre-building-for-ios-tvos-or-watchos). Make sure to embed all of the required frameworks listed [here](https://github.com/stripe/stripe-ios/tree/master/StripePaymentSheet/README.md#manual-linking). 1. In the future, to update to the latest version of the SDK, run the following command: ```bash carthage update stripe-ios --platform ios ``` #### Manual Framework 1. Head to our [GitHub releases page](https://github.com/stripe/stripe-ios/releases/latest) and download and unzip **Stripe.xcframework.zip**. 1. Drag **StripePaymentSheet.xcframework** to the **Embedded Binaries** section of the **General** settings in your Xcode project. Make sure to select **Copy items if needed**. 1. Repeat step 2 for all required frameworks listed [here](https://github.com/stripe/stripe-ios/tree/master/StripePaymentSheet/README.md#manual-linking). 1. In the future, to update to the latest version of our SDK, repeat steps 1–3. > For details on the latest SDK release and past versions, see the [Releases](https://github.com/stripe/stripe-ios/releases) page on GitHub. To receive notifications when a new release is published, [watch releases](https://help.github.com/en/articles/watching-and-unwatching-releases-for-a-repository#watching-releases-for-a-repository) for the repository. ## Enable payment methods Card payments are enabled by default. View your [payment methods settings](https://dashboard.stripe.com/settings/payment_methods) to enable more payment methods you want to support. ## Add an endpoint [Server-side] > #### Note > > To display the PaymentSheet before you create a PaymentIntent, see [Collect payment details before creating an Intent](https://docs.stripe.com/payments/accept-a-payment-deferred.md?type=payment). If your Connect platform uses [customer-configured Accounts](https://docs.stripe.com/api/v2/core/accounts/create.md#v2_create_accounts-configuration-customer), use our [guide](https://docs.stripe.com/connect/use-accounts-as-customers.md) to replace `Customer` and event references in your code with the equivalent Accounts v2 API references. This integration uses three Stripe API objects: 1. [PaymentIntent](https://docs.stripe.com/api/payment_intents.md): Stripe uses this to represent your intent to collect payment from a customer, tracking your charge attempts and payment state changes throughout the process. 1. [Customer](https://docs.stripe.com/api/customers.md): To set up a payment method for future payments, you must attach it to a *Customer* (Customer objects represent customers of your business. They let you reuse payment methods and give you the ability to track multiple payments). Create a Customer object when your customer creates an account with your business. If your customer is making a payment as a guest, you can create a Customer object before payment and associate it with your own internal representation of the customer’s account later. 1. [CustomerSession](https://docs.stripe.com/api/customer_sessions.md): Information on the Customer object is sensitive, and can’t be retrieved directly from an app. A CustomerSession grants the SDK temporary scoped access to the Customer and provides additional configuration options. See a complete list of [configuration options](https://docs.stripe.com/api/customer_sessions/create.md#create_customer_session-components). For security reasons, your app can’t create these objects. Instead, add an endpoint on your server that: 1. Retrieves the Customer, or creates a new one. 1. Creates a [CustomerSession](https://docs.stripe.com/api/customer_sessions.md) for the Customer. 1. Creates a PaymentIntent with the [amount](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-amount), [currency](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-currency), and [customer](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-customer), [setup_future_usage](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-setup_future_usage) . 1. Returns the Payment Intent’s *client secret* (The client secret is a unique key returned from Stripe as part of a PaymentIntent. This key lets the client access important fields from the PaymentIntent (status, amount, currency) while hiding sensitive ones (metadata, customer)), the CustomerSession’s `client_secret`, the Customer’s [id](https://docs.stripe.com/api/customers/object.md#customer_object-id), and your [publishable key](https://dashboard.stripe.com/apikeys) to your app. > The mobile Payment Element only supports `setup_future_usage` with cards and US bank accounts. The payment methods shown to customers during the checkout process are also included on the PaymentIntent. You can let Stripe pull payment methods from your Dashboard settings or you can list them manually. Regardless of the option you choose, know that the currency passed in the PaymentIntent filters the payment methods shown to the customer. For example, if you pass `eur` on the PaymentIntent and have OXXO enabled in the Dashboard, OXXO won’t be shown to the customer because OXXO doesn’t support `eur` payments. Unless your integration requires a code-based option for offering payment methods, Stripe recommends the automated option. This is because Stripe evaluates the currency, payment method restrictions, and other parameters to determine the list of supported payment methods. Payment methods that increase conversion and that are most relevant to the currency and customer’s location are prioritized. #### Manage payment methods from the Dashboard You can manage payment methods from the [Dashboard](https://dashboard.stripe.com/settings/payment_methods). Stripe handles the return of eligible payment methods based on factors such as the transaction’s amount, currency, and payment flow. The PaymentIntent is created using the payment methods you configured in the Dashboard. If you don’t want to use the Dashboard or if you want to specify payment methods manually, you can list them using the `payment_method_types` attribute. #### curl ```bash # Create a Customer (use an existing Customer ID if this is a returning customer) curl https://api.stripe.com/v1/customers \ -u <>: \ -X "POST" \ -H "Stripe-Account: {{CONNECTED_ACCOUNT_ID}}" # Create an CustomerSession for the Customer curl https://api.stripe.com/v1/customer_sessions \ -u <>: \ -X "POST" \ -d "customer"="{{CUSTOMER_ID}}" \ -d "components[mobile_payment_element][enabled]"=true \ -d "components[mobile_payment_element][features][payment_method_save]"=enabled \ -d "components[mobile_payment_element][features][payment_method_redisplay]"=enabled \ -d "components[mobile_payment_element][features][payment_method_remove]"=enabled # Create a PaymentIntent curl https://api.stripe.com/v1/payment_intents \ -u <>: \ -X "POST" \ -d "customer"="{{CUSTOMER_ID}}" \ -d "amount"=1099 \ -d "currency"="eur" \ -d "setup_future_usage"="off_session" \ # In the latest version of the API, specifying the `automatic_payment_methods` parameter # is optional because Stripe enables its functionality by default. -d "automatic_payment_methods[enabled]"=true \ ``` #### Listing payment methods manually #### curl ```bash # Create a Customer (use an existing Customer ID if this is a returning customer) curl https://api.stripe.com/v1/customers \ -u <>: \ -X "POST" \ -H "Stripe-Account: {{CONNECTED_ACCOUNT_ID}}" # Create an CustomerSession for the Customer curl https://api.stripe.com/v1/customer_sessions \ -u <>: \ -X "POST" \ -d "customer"="{{CUSTOMER_ID}}" \ -d "components[mobile_payment_element][enabled]"=true \ -d "components[mobile_payment_element][features][payment_method_save]"=enabled \ -d "components[mobile_payment_element][features][payment_method_redisplay]"=enabled \ -d "components[mobile_payment_element][features][payment_method_remove]"=enabled # Create a PaymentIntent curl https://api.stripe.com/v1/payment_intents \ -u <>: \ -X "POST" \ -d "customer"="{{CUSTOMER_ID}}" \ -d "amount"=1099 \ -d "currency"="eur" \ -d "setup_future_usage"="off_session" \ -d "payment_method_types[]"="card" \ ``` > Each payment method needs to support the currency passed in the PaymentIntent and your business needs to be based in one of the countries each payment method supports. See the [Payment method integration options](https://docs.stripe.com/payments/payment-methods/integration-options.md) page for more details about what’s supported. ## Collect payment details [Client-side] To display the mobile Payment Element on your checkout screen, make sure you: - Display the products the customer is purchasing along with the total amount - Use the [Address Element](https://docs.stripe.com/elements/address-element.md?platform=ios) to collect any required shipping information from the customer - Add a checkout button to display Stripe’s UI #### UIKit In your app’s checkout screen, fetch the PaymentIntent client secret, CustomerSession client secret, Customer ID, and publishable key from the endpoint you created in the previous step. Use `STPAPIClient.shared` to set your publishable key and initialize the [PaymentSheet](https://stripe.dev/stripe-ios/stripe-paymentsheet/Classes/PaymentSheet.html). #### iOS (Swift) ```swift import UIKit@_spi(CustomerSessionBetaAccess) import StripePaymentSheet class CheckoutViewController: UIViewController { @IBOutlet weak var checkoutButton: UIButton! var paymentSheet: PaymentSheet? let backendCheckoutUrl = URL(string: "Your backend endpoint/payment-sheet")! // Your backend endpoint override func viewDidLoad() { super.viewDidLoad() checkoutButton.addTarget(self, action: #selector(didTapCheckoutButton), for: .touchUpInside) checkoutButton.isEnabled = false // MARK: Fetch the PaymentIntent client secret, CustomerSession client secret, Customer ID, and publishable key var request = URLRequest(url: backendCheckoutUrl) request.httpMethod = "POST" let task = URLSession.shared.dataTask(with: request, completionHandler: { [weak self] (data, response, error) in guard let data = data, let json = try? JSONSerialization.jsonObject(with: data, options: []) as? [String : Any], let customerId = json["customer"] as? String, let customerSessionClientSecret = json["customerSessionClientSecret"] as? String, let paymentIntentClientSecret = json["paymentIntent"] as? String, let publishableKey = json["publishableKey"] as? String, let self = self else { // Handle error return } STPAPIClient.shared.publishableKey = publishableKey// MARK: Create a PaymentSheet instance var configuration = PaymentSheet.Configuration() configuration.merchantDisplayName = "Example, Inc." configuration.customer = .init(id: customerId, customerSessionClientSecret: customerSessionClientSecret) // Set `allowsDelayedPaymentMethods` to true if your business handles // delayed notification payment methods like US bank accounts. configuration.allowsDelayedPaymentMethods = true self.paymentSheet = PaymentSheet(paymentIntentClientSecret:paymentIntentClientSecret, configuration: configuration) DispatchQueue.main.async { self.checkoutButton.isEnabled = true } }) task.resume() } } ``` When the customer taps the **Checkout** button, call `present` to present the PaymentSheet. After the customer completes the payment, Stripe dismisses the PaymentSheet and calls the completion block with [PaymentSheetResult](https://stripe.dev/stripe-ios/stripe-paymentsheet/Enums/PaymentSheetResult.html). #### iOS (Swift) ```swift @objc func didTapCheckoutButton() { // MARK: Start the checkout process paymentSheet?.present(from: self) { paymentResult in // MARK: Handle the payment result switch paymentResult { case .completed: print("Your order is confirmed") case .canceled: print("Canceled!") case .failed(let error): print("Payment failed: \(error)") } } } ``` #### SwiftUI Create an `ObservableObject` model for your checkout screen. This model publishes a [PaymentSheet](https://stripe.dev/stripe-ios/stripe-paymentsheet/Classes/PaymentSheet.html) and a [PaymentSheetResult](https://stripe.dev/stripe-ios/stripe-paymentsheet/Enums/PaymentSheetResult.html). ```swift import StripePaymentSheet import SwiftUI class CheckoutViewModel: ObservableObject { let backendCheckoutUrl = URL(string: "Your backend endpoint/payment-sheet")! // Your backend endpoint @Published var paymentSheet: PaymentSheet? @Published var paymentResult: PaymentSheetResult? } ``` Fetch the PaymentIntent client secret, CustomerSession client secret, Customer ID, and publishable key from the endpoint you created in the previous step. Use `STPAPIClient.shared` to set your publishable key and initialize the [PaymentSheet](https://stripe.dev/stripe-ios/stripe-paymentsheet/Classes/PaymentSheet.html). ```swift @_spi(CustomerSessionBetaAccess) import StripePaymentSheet import SwiftUI class CheckoutViewModel: ObservableObject { let backendCheckoutUrl = URL(string: "Your backend endpoint/payment-sheet")! // Your backend endpoint @Published var paymentSheet: PaymentSheet? @Published var paymentResult: PaymentSheetResult? func preparePaymentSheet() { // MARK: Fetch thePaymentIntent and Customer information from the backend var request = URLRequest(url: backendCheckoutUrl) request.httpMethod = "POST" let task = URLSession.shared.dataTask(with: request, completionHandler: { [weak self] (data, response, error) in guard let data = data, let json = try? JSONSerialization.jsonObject(with: data, options: []) as? [String : Any], let customerId = json["customer"] as? String, let customerSessionClientSecret = json["customerSessionClientSecret"] as? String, letpaymentIntentClientSecret = json["paymentIntent"] as? String, let publishableKey = json["publishableKey"] as? String, let self = self else { // Handle error return } STPAPIClient.shared.publishableKey = publishableKey// MARK: Create a PaymentSheet instance var configuration = PaymentSheet.Configuration() configuration.merchantDisplayName = "Example, Inc." configuration.customer = .init(id: customerId, customerSessionClientSecret: customerSessionClientSecret) // Set `allowsDelayedPaymentMethods` to true if your business handles // delayed notification payment methods like US bank accounts. configuration.allowsDelayedPaymentMethods = true DispatchQueue.main.async { self.paymentSheet = PaymentSheet(paymentIntentClientSecret:paymentIntentClientSecret, configuration: configuration) } }) task.resume() } } struct CheckoutView: View { @ObservedObject var model = CheckoutViewModel() var body: some View { VStack { if model.paymentSheet != nil { Text("Ready to pay.") } else { Text("Loading…") } }.onAppear { model.preparePaymentSheet() } } } ``` Add a [PaymentSheet.PaymentButton](https://stripe.dev/stripe-ios/stripe-paymentsheet/Classes/PaymentSheet/PaymentButton.html) to your `View`. This behaves similarly to a SwiftUI `Button`, which allows you to customize it by adding a `View`. When you tap the button, it displays the PaymentSheet. After you complete the payment, Stripe dismisses the PaymentSheet and calls the `onCompletion` handler with a [PaymentSheetResult](https://stripe.dev/stripe-ios/stripe-paymentsheet/Enums/PaymentSheetResult.html) object. ```swift @_spi(CustomerSessionBetaAccess) import StripePaymentSheet import SwiftUI class CheckoutViewModel: ObservableObject { let backendCheckoutUrl = URL(string: "Your backend endpoint/payment-sheet")! // Your backend endpoint @Published var paymentSheet: PaymentSheet? @Published var paymentResult: PaymentSheetResult? func preparePaymentSheet() { // MARK: Fetch the PaymentIntent and Customer information from the backend var request = URLRequest(url: backendCheckoutUrl) request.httpMethod = "POST" let task = URLSession.shared.dataTask(with: request, completionHandler: { [weak self] (data, response, error) in guard let data = data, let json = try? JSONSerialization.jsonObject(with: data, options: []) as? [String : Any], let customerId = json["customer"] as? String, let customerSessionClientSecret = json["customerSessionClientSecret"] as? String, let paymentIntentClientSecret = json["paymentIntent"] as? String, let publishableKey = json["publishableKey"] as? String, let self = self else { // Handle error return } STPAPIClient.shared.publishableKey = publishableKey // MARK: Create a PaymentSheet instance var configuration = PaymentSheet.Configuration() configuration.merchantDisplayName = "Example, Inc." configuration.customer = .init(id: customerId, customerSessionClientSecret: customerSessionClientSecret) // Set `allowsDelayedPaymentMethods` to true if your business can handle payment methods // that complete payment after a delay, like SEPA Debit and Sofort. configuration.allowsDelayedPaymentMethods = true DispatchQueue.main.async { self.paymentSheet = PaymentSheet(paymentIntentClientSecret: paymentIntentClientSecret, configuration: configuration) } }) task.resume() } func onPaymentCompletion(result: PaymentSheetResult) { self.paymentResult = result } } struct CheckoutView: View { @ObservedObject var model = CheckoutViewModel() var body: some View { VStack {if let paymentSheet = model.paymentSheet { PaymentSheet.PaymentButton( paymentSheet: paymentSheet, onCompletion: model.onPaymentCompletion ) { Text("Buy") } } else { Text("Loading…") }if let result = model.paymentResult { switch result { case .completed: Text("Payment complete") case .failed(let error): Text("Payment failed: \(error.localizedDescription)") case .canceled: Text("Payment canceled.") } } }.onAppear { model.preparePaymentSheet() } } } ``` If `PaymentSheetResult` is `.completed`, inform the user (for example, by displaying an order confirmation screen). Setting `allowsDelayedPaymentMethods` to true allows [delayed notification](https://docs.stripe.com/payments/payment-methods.md#payment-notification) payment methods like US bank accounts. For these payment methods, the final payment status isn’t known when the `PaymentSheet` completes, and instead succeeds or fails later. If you support these types of payment methods, inform the customer their order is confirmed and only fulfill their order (for example, ship their product) when the payment is successful. ## Set up a return URL [Client-side] The customer might navigate away from your app to authenticate (for example, in Safari or their banking app). To allow them to automatically return to your app after authenticating, [configure a custom URL scheme](https://developer.apple.com/documentation/xcode/defining-a-custom-url-scheme-for-your-app) and set up your app delegate to forward the URL to the SDK. Stripe doesn’t support [universal links](https://developer.apple.com/documentation/xcode/allowing-apps-and-websites-to-link-to-your-content). #### SceneDelegate #### Swift ```swift // This method handles opening custom URL schemes (for example, "your-app://stripe-redirect") func scene(_ scene: UIScene, openURLContexts URLContexts: Set) { guard let url = URLContexts.first?.url else { return } let stripeHandled = StripeAPI.handleURLCallback(with: url) if (!stripeHandled) { // This was not a Stripe url – handle the URL normally as you would } } ``` #### AppDelegate #### Swift ```swift // This method handles opening custom URL schemes (for example, "your-app://stripe-redirect") func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey: Any] = [:]) -> Bool { let stripeHandled = StripeAPI.handleURLCallback(with: url) if (stripeHandled) { return true } else { // This was not a Stripe url – handle the URL normally as you would } return false } ``` #### SwiftUI #### Swift ```swift @main struct MyApp: App { var body: some Scene { WindowGroup { Text("Hello, world!").onOpenURL { incomingURL in let stripeHandled = StripeAPI.handleURLCallback(with: incomingURL) if (!stripeHandled) { // This was not a Stripe url – handle the URL normally as you would } } } } } ``` Additionally, set the [returnURL](https://stripe.dev/stripe-ios/stripe-paymentsheet/Classes/PaymentSheet/Configuration.html#/s:6Stripe12PaymentSheetC13ConfigurationV9returnURLSSSgvp) on your [PaymentSheet.Configuration](https://stripe.dev/stripe-ios/stripe-paymentsheet/Classes/PaymentSheet/Configuration.html) object to the URL for your app. ```swift var configuration = PaymentSheet.Configuration() configuration.returnURL = "your-app://stripe-redirect" ``` ## Handle post-payment events [Server-side] Stripe sends a [payment_intent.succeeded](https://docs.stripe.com/api/events/types.md#event_types-payment_intent.succeeded) event when the payment completes. Use the [Dashboard webhook tool](https://dashboard.stripe.com/webhooks) or follow the [webhook guide](https://docs.stripe.com/webhooks/quickstart.md) to receive these events and run actions, such as sending an order confirmation email to your customer, logging the sale in a database, or starting a shipping workflow. Listen for these events rather than waiting on a callback from the client. On the client, the customer could close the browser window or quit the app before the callback executes, and malicious clients could manipulate the response. Setting up your integration to listen for asynchronous events is what enables you to accept [different types of payment methods](https://stripe.com/payments/payment-methods-guide) with a single integration. In addition to handling the `payment_intent.succeeded` event, we recommend handling these other events when collecting payments with the Payment Element: | Event | Description | Action | | ------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | [payment_intent.succeeded](https://docs.stripe.com/api/events/types.md?lang=php#event_types-payment_intent.succeeded) | Sent when a customer successfully completes a payment. | Send the customer an order confirmation and *fulfill* (Fulfillment is the process of providing the goods or services purchased by a customer, typically after payment is collected) their order. | | [payment_intent.processing](https://docs.stripe.com/api/events/types.md?lang=php#event_types-payment_intent.processing) | Sent when a customer successfully initiates a payment, but the payment has yet to complete. This event is most commonly sent when the customer initiates a bank debit. It’s followed by either a `payment_intent.succeeded` or `payment_intent.payment_failed` event in the future. | Send the customer an order confirmation that indicates their payment is pending. For digital goods, you might want to fulfill the order before waiting for payment to complete. | | [payment_intent.payment_failed](https://docs.stripe.com/api/events/types.md?lang=php#event_types-payment_intent.payment_failed) | Sent when a customer attempts a payment, but the payment fails. | If a payment transitions from `processing` to `payment_failed`, offer the customer another attempt to pay. | ## Charge the saved Payment Method later [Server-side] > #### Compliance > > You’re responsible for your compliance with all applicable laws, regulations, and network rules when saving a customer’s payment details. When rendering past payment methods to your end customer for future purchases, make sure you’re listing payment methods where you’ve collected consent from the customer to save the payment method details for this specific future use. To differentiate between payment methods attached to customers that can and can’t be presented to your end customer as a saved payment method for future purchases, use the [allow_redisplay](https://docs.stripe.com/api/payment_methods/object.md#payment_method_object-allow_redisplay) parameter. When you’re ready to charge your customer *off-session* (A payment is described as off-session if it occurs without the direct involvement of the customer, using previously-collected payment information), use the Customer and PaymentMethod IDs to create a PaymentIntent. To find a payment method to charge, list the payment methods associated with your customer. This example lists cards but you can list any supported [type](https://docs.stripe.com/api/payment_methods/object.md#payment_method_object-type). ```curl curl -G https://api.stripe.com/v1/payment_methods \ -u "<>:" \ -d "customer={{CUSTOMER_ID}}" \ -d type=card ``` When you have the Customer and PaymentMethod IDs, create a PaymentIntent with the amount and currency of the payment. Set a few other parameters to make the off-session payment: - Set [off_session](https://docs.stripe.com/api/payment_intents/confirm.md#confirm_payment_intent-off_session) to `true` to indicate that the customer isn’t in your checkout flow during a payment attempt and can’t fulfill an authentication request made by a partner, such as a card issuer, bank, or other payment institution. If, during your checkout flow, a partner requests authentication, Stripe requests exemptions using customer information from a previous *on-session* (A payment is described as on-session if it occurs while the customer is actively in your checkout flow and able to authenticate the payment method) transaction. If the conditions for exemption aren’t met, the PaymentIntent might throw an error. - Set the value of the PaymentIntent’s [confirm](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-confirm) property to `true`, which causes confirmation to occur immediately when the PaymentIntent is created. - Set [payment_method](https://docs.stripe.com/api.md#create_payment_intent-payment_method) to the ID of the PaymentMethod and [customer](https://docs.stripe.com/api.md#create_payment_intent-customer) to the ID of the Customer. #### curl ```bash curl https://api.stripe.com/v1/payment_intents \ -u <>: \ -d amount=1099 \ -d currency=usd \ # In the latest version of the API, specifying the `automatic_payment_methods` parameter is optional because Stripe enables its functionality by default. -d "automatic_payment_methods[enabled]"=true \-d customer="{{CUSTOMER_ID}}" \ -d payment_method="{{PAYMENT_METHOD_ID}}" \ -d return_url="https://example.com/order/123/complete" \ -d off_session=true \ -d confirm=true ``` ## Test the integration #### Cards | Payment method | Scenario | How to test | | -------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------- | | Credit card | The card setup succeeds and doesn’t require *authentication* (Strong Customer Authentication (SCA) is a regulatory requirement in effect as of September 14, 2019, that impacts many European online payments. It requires customers to use two-factor authentication like 3D Secure to verify their purchase). | Fill out the credit card form using the credit card number `4242 4242 4242 4242` with any expiration, CVC, and postal code. | | Credit card | The card requires authentication for the initial setup, then succeeds for subsequent payments. | Fill out the credit card form using the credit card number `4000 0025 0000 3155` with any expiration, CVC, and postal code. | | Credit card | The card requires authentication for the initial setup and also requires authentication for subsequent payments. | Fill out the credit card form using the credit card number `4000 0027 6000 3184` with any expiration, CVC, and postal code. | | Credit card | The card is declined during setup. | Fill out the credit card form using the credit card number `4000 0000 0000 9995` with any expiration, CVC, and postal code. | ## Optional: Enable Apple Pay > If your checkout screen has a dedicated **Apple Pay button**, follow the [Apple Pay guide](https://docs.stripe.com/apple-pay.md#present-payment-sheet) and use `ApplePayContext` to collect payment from your Apple Pay button. You can use `PaymentSheet` to handle other payment method types. ### Register for an Apple Merchant ID Obtain an Apple Merchant ID by [registering for a new identifier](https://developer.apple.com/account/resources/identifiers/add/merchant) on the Apple Developer website. Fill out the form with a description and identifier. Your description is for your own records and you can modify it in the future. Stripe recommends using the name of your app as the identifier (for example, `merchant.com.{{YOUR_APP_NAME}}`). ### Create a new Apple Pay certificate Create a certificate for your app to encrypt payment data. Go to the [iOS Certificate Settings](https://dashboard.stripe.com/settings/ios_certificates) in the Dashboard, click **Add new application**, and follow the guide. Download a Certificate Signing Request (CSR) file to get a secure certificate from Apple that allows you to use Apple Pay. One CSR file must be used to issue exactly one certificate. If you switch your Apple Merchant ID, you must go to the [iOS Certificate Settings](https://dashboard.stripe.com/settings/ios_certificates) in the Dashboard to obtain a new CSR and certificate. ### Integrate with Xcode Add the Apple Pay capability to your app. In Xcode, open your project settings, click the **Signing & Capabilities** tab, and add the **Apple Pay** capability. You might be prompted to log in to your developer account at this point. Select the merchant ID you created earlier, and your app is ready to accept Apple Pay. ![](https://b.stripecdn.com/docs-statics-srv/assets/xcode.a701d4c1922d19985e9c614a6f105bf1.png) Enable the Apple Pay capability in Xcode ### Add Apple Pay #### One-time payment To add Apple Pay to PaymentSheet, set [applePay](https://stripe.dev/stripe-ios/stripe-paymentsheet/Classes/PaymentSheet/Configuration.html#/s:6Stripe12PaymentSheetC13ConfigurationV8applePayAC05ApplefD0VSgvp) after initializing `PaymentSheet.Configuration` with your Apple merchant ID and the [country code of your business](https://dashboard.stripe.com/settings/account). #### iOS (Swift) ```swift var configuration = PaymentSheet.Configuration() configuration.applePay = .init( merchantId: "merchant.com.your_app_name", merchantCountryCode: "US" ) ``` #### Recurring payments To add Apple Pay to PaymentSheet, set [applePay](https://stripe.dev/stripe-ios/stripe-paymentsheet/Classes/PaymentSheet/Configuration.html#/s:6Stripe12PaymentSheetC13ConfigurationV8applePayAC05ApplefD0VSgvp) after initializing `PaymentSheet.Configuration` with your Apple merchant ID and the [country code of your business](https://dashboard.stripe.com/settings/account). Per [Apple’s guidelines](https://developer.apple.com/design/human-interface-guidelines/apple-pay#Supporting-subscriptions) for recurring payments, you must also set additional attributes on the `PKPaymentRequest`. Add a handler in [ApplePayConfiguration.paymentRequestHandlers](https://stripe.dev/stripe-ios/stripepaymentsheet/documentation/stripepaymentsheet/paymentsheet/applepayconfiguration/handlers/paymentrequesthandler) to configure the [PKPaymentRequest.paymentSummaryItems](https://developer.apple.com/documentation/passkit/pkpaymentrequest/1619231-paymentsummaryitems) with the amount you intend to charge (for example, 9.95 USD a month). You can also adopt [merchant tokens](https://developer.apple.com/apple-pay/merchant-tokens/) by setting the `recurringPaymentRequest` or `automaticReloadPaymentRequest` properties on the `PKPaymentRequest`. To learn more about how to use recurring payments with Apple Pay, see [Apple’s PassKit documentation](https://developer.apple.com/documentation/passkit/pkpaymentrequest). #### iOS (Swift) ```swift let customHandlers = PaymentSheet.ApplePayConfiguration.Handlers( paymentRequestHandler: { request in // PKRecurringPaymentSummaryItem is available on iOS 15 or later if #available(iOS 15.0, *) { let billing = PKRecurringPaymentSummaryItem(label: "My Subscription", amount: NSDecimalNumber(string: "59.99")) // Payment starts today billing.startDate = Date() // Payment ends in one year billing.endDate = Date().addingTimeInterval(60 * 60 * 24 * 365) // Pay once a month. billing.intervalUnit = .month billing.intervalCount = 1 // recurringPaymentRequest is only available on iOS 16 or later if #available(iOS 16.0, *) { request.recurringPaymentRequest = PKRecurringPaymentRequest(paymentDescription: "Recurring", regularBilling: billing, managementURL: URL(string: "https://my-backend.example.com/customer-portal")!) request.recurringPaymentRequest?.billingAgreement = "You'll be billed $59.99 every month for the next 12 months. To cancel at any time, go to Account and click 'Cancel Membership.'" } request.paymentSummaryItems = [billing] request.currencyCode = "USD" } else { // On older iOS versions, set alternative summary items. request.paymentSummaryItems = [PKPaymentSummaryItem(label: "Monthly plan starting July 1, 2022", amount: NSDecimalNumber(string: "59.99"), type: .final)] } return request } ) var configuration = PaymentSheet.Configuration() configuration.applePay = .init(merchantId: "merchant.com.your_app_name", merchantCountryCode: "US", customHandlers: customHandlers) ``` ### Order tracking To add [order tracking](https://developer.apple.com/design/human-interface-guidelines/technologies/wallet/designing-order-tracking) information in iOS 16 or later, configure an [authorizationResultHandler](https://stripe.dev/stripe-ios/stripepaymentsheet/documentation/stripepaymentsheet/paymentsheet/applepayconfiguration/handlers/authorizationresulthandler) in your `PaymentSheet.ApplePayConfiguration.Handlers`. Stripe calls your implementation after the payment is complete, but before iOS dismisses the Apple Pay sheet. In your `authorizationResultHandler` implementation, fetch the order details from your server for the completed order. Add the details to the provided [PKPaymentAuthorizationResult](https://developer.apple.com/documentation/passkit/pkpaymentauthorizationresult) and return the modified result. To learn more about order tracking, see [Apple’s Wallet Orders documentation](https://developer.apple.com/documentation/walletorders). #### iOS (Swift) ```swift let customHandlers = PaymentSheet.ApplePayConfiguration.Handlers( authorizationResultHandler: { result in do { // Fetch the order details from your service let myOrderDetails = try await MyAPIClient.shared.fetchOrderDetails(orderID: orderID) result.orderDetails = PKPaymentOrderDetails( orderTypeIdentifier: myOrderDetails.orderTypeIdentifier, // "com.myapp.order" orderIdentifier: myOrderDetails.orderIdentifier, // "ABC123-AAAA-1111" webServiceURL: myOrderDetails.webServiceURL, // "https://my-backend.example.com/apple-order-tracking-backend" authenticationToken: myOrderDetails.authenticationToken) // "abc123" // Return your modified PKPaymentAuthorizationResult return result } catch { return PKPaymentAuthorizationResult(status: .failure, errors: [error]) } } ) var configuration = PaymentSheet.Configuration() configuration.applePay = .init(merchantId: "merchant.com.your_app_name", merchantCountryCode: "US", customHandlers: customHandlers) ``` ## Enable card scanning To enable card scanning support for iOS, set the `NSCameraUsageDescription` (**Privacy - Camera Usage Description**) in the `Info.plist` of your application, and provide a reason for accessing the camera (for example, “To scan cards”). ## Optional: Customize the sheet All customization is configured through the [PaymentSheet.Configuration](https://stripe.dev/stripe-ios/stripe-paymentsheet/Classes/PaymentSheet/Configuration.html) object. ### Appearance Customize colors, fonts, and so on to match the look and feel of your app by using the [appearance API](https://docs.stripe.com/elements/appearance-api/mobile.md?platform=ios). ### Payment method layout Configure the layout of payment methods in the sheet using [paymentMethodLayout](https://stripe.dev/stripe-ios/stripepaymentsheet/documentation/stripepaymentsheet/paymentsheet/configuration-swift.struct/paymentmethodlayout). You can display them horizontally, vertically, or let Stripe optimize the layout automatically. ![](https://b.stripecdn.com/docs-statics-srv/assets/ios-mpe-payment-method-layouts.9d0513e2fcec5660378ba1824d952054.png) #### Swift ```swift var configuration = PaymentSheet.Configuration() configuration.paymentMethodLayout = .automatic ``` ### Collect users addresses Collect local and international shipping or billing addresses from your customers using the [Address Element](https://docs.stripe.com/elements/address-element.md?platform=ios). ### Merchant display name Specify a customer-facing business name by setting [merchantDisplayName](https://stripe.dev/stripe-ios/stripe-paymentsheet/Classes/PaymentSheet/Configuration.html#/s:18StripePaymentSheet0bC0C13ConfigurationV19merchantDisplayNameSSvp). By default, this is your app’s name. #### Swift ```swift var configuration = PaymentSheet.Configuration() configuration.merchantDisplayName = "My app, Inc." ``` ### Dark mode `PaymentSheet` automatically adapts to the user’s system-wide appearance settings (light and dark mode). If your app doesn’t support dark mode, you can set [style](https://stripe.dev/stripe-ios/stripe-paymentsheet/Classes/PaymentSheet/Configuration.html#/s:18StripePaymentSheet0bC0C13ConfigurationV5styleAC18UserInterfaceStyleOvp) to `alwaysLight` or `alwaysDark` mode. ```swift var configuration = PaymentSheet.Configuration() configuration.style = .alwaysLight ``` ### Default billing details To set default values for billing details collected in the payment sheet, configure the `defaultBillingDetails` property. The `PaymentSheet` pre-populates its fields with the values that you provide. ```swift var configuration = PaymentSheet.Configuration() configuration.defaultBillingDetails.address.country = "US" configuration.defaultBillingDetails.email = "foo@bar.com" ``` ### Billing details collection Use `billingDetailsCollectionConfiguration` to specify how you want to collect billing details in the payment sheet. You can collect your customer’s name, email, phone number, and address. If you only want to billing details required by the payment method, set `billingDetailsCollectionConfiguration.attachDefaultsToPaymentMethod` to true. In that case, the `PaymentSheet.Configuration.defaultBillingDetails` are set as the payment method’s [billing details](https://docs.stripe.com/api/payment_methods/object.md?lang=node#payment_method_object-billing_details). If you want to collect additional billing details that aren’t necessarily required by the payment method, set `billingDetailsCollectionConfiguration.attachDefaultsToPaymentMethod` to false. In that case, the billing details collected through the `PaymentSheet` are set as the payment method’s billing details. ```swift var configuration = PaymentSheet.Configuration() configuration.defaultBillingDetails.email = "foo@bar.com" configuration.billingDetailsCollectionConfiguration.name = .always configuration.billingDetailsCollectionConfiguration.email = .never configuration.billingDetailsCollectionConfiguration.address = .full configuration.billingDetailsCollectionConfiguration.attachDefaultsToPaymentMethod = true ``` > Consult with your legal counsel regarding laws that apply to collecting information. Only collect phone numbers if you need them for the transaction. ## Optional: Complete payment in your UI You can present the Payment Sheet to only collect payment method details and then later call a `confirm` method to complete payment in your app’s UI. This is useful if you have a custom buy button or require additional steps after you collect payment details. ![](https://b.stripecdn.com/docs-statics-srv/assets/ios-multi-step.cd631ea4f1cd8cf3f39b6b9e1e92b6c5.png) Complete the payment in your app’s UI #### UIKit The following steps walk you through how to complete payment in your app’s UI. See our sample integration out on [GitHub](https://github.com/stripe/stripe-ios/blob/master/Example/PaymentSheet%20Example/PaymentSheet%20Example/ExampleCustomCheckoutViewController.swift). 1. First, initialize [PaymentSheet.FlowController](https://stripe.dev/stripe-ios/stripepaymentsheet/documentation/stripepaymentsheet/paymentsheet/flowcontroller) instead of `PaymentSheet` and update your UI with its `paymentOption` property. This property contains an image and label representing the customer’s initially selected, default payment method. ```swift PaymentSheet.FlowController.create(paymentIntentClientSecret: paymentIntentClientSecret, configuration: configuration) { [weak self] result in switch result { case .failure(let error): print(error) case .success(let paymentSheetFlowController): self?.paymentSheetFlowController = paymentSheetFlowController // Update your UI using paymentSheetFlowController.paymentOption } } ``` 1. Next, call `presentPaymentOptions` to collect payment details. When completed, update your UI again with the `paymentOption` property. ```swift paymentSheetFlowController.presentPaymentOptions(from: self) { // Update your UI using paymentSheetFlowController.paymentOption } ``` 1. Finally, call `confirm`. ```swift paymentSheetFlowController.confirm(from: self) { paymentResult in // MARK: Handle the payment result switch paymentResult { case .completed: print("Payment complete!") case .canceled: print("Canceled!") case .failed(let error): print(error) } } ``` #### SwiftUI The following steps walk you through how to complete payment in your app’s UI. See our sample integration out on [GitHub](https://github.com/stripe/stripe-ios/blob/master/Example/PaymentSheet%20Example/PaymentSheet%20Example/ExampleSwiftUICustomPaymentFlow.swift). 1. First, initialize [PaymentSheet.FlowController](https://stripe.dev/stripe-ios/stripepaymentsheet/documentation/stripepaymentsheet/paymentsheet/flowcontroller) instead of `PaymentSheet`. Its `paymentOption` property contains an image and label representing the customer’s currently selected payment method, which you can use in your UI. ```swift PaymentSheet.FlowController.create(paymentIntentClientSecret: paymentIntentClientSecret, configuration: configuration) { [weak self] result in switch result { case .failure(let error): print(error) case .success(let paymentSheetFlowController): self?.paymentSheetFlowController = paymentSheetFlowController // Use the paymentSheetFlowController.paymentOption properties in your UI myPaymentMethodLabel = paymentSheetFlowController.paymentOption?.label ?? "Select a payment method" myPaymentMethodImage = paymentSheetFlowController.paymentOption?.image ?? UIImage(systemName: "square.and.pencil")! } } ``` 1. Use [PaymentSheet.FlowController.PaymentOptionsButton](https://stripe.dev/stripe-ios/stripepaymentsheet/documentation/stripepaymentsheet/paymentsheet/flowcontroller/paymentoptionsbutton) to wrap the button that presents the sheet to collect payment details. When `PaymentSheet.FlowController` calls the `onSheetDismissed` argument, the `paymentOption` for the `PaymentSheet.FlowController` instance reflects the currently selected payment method. ```swift PaymentSheet.FlowController.PaymentOptionsButton( paymentSheetFlowController: paymentSheetFlowController, onSheetDismissed: { myPaymentMethodLabel = paymentSheetFlowController.paymentOption?.label ?? "Select a payment method" myPaymentMethodImage = paymentSheetFlowController.paymentOption?.image ?? UIImage(systemName: "square.and.pencil")! }, content: { /* An example button */ HStack { Text(myPaymentMethodLabel) Image(uiImage: myPaymentMethodImage) } } ) ``` 1. Use [PaymentSheet.FlowController.PaymentOptionsButton](https://stripe.dev/stripe-ios/stripepaymentsheet/documentation/stripepaymentsheet/paymentsheet/flowcontroller/paymentoptionsbutton) to wrap the button that confirms the payment. ```swift PaymentSheet.FlowController.ConfirmButton( paymentSheetFlowController: paymentSheetFlowController, onCompletion: { result in // MARK: Handle the payment result switch result { case .completed: print("Payment complete!") case .canceled: print("Canceled!") case .failed(let error): print(error) } }, content: { /* An example button */ Text("Pay") } ) ``` Setting `allowsDelayedPaymentMethods` to true allows [delayed notification](https://docs.stripe.com/payments/payment-methods.md#payment-notification) payment methods like US bank accounts. For these payment methods, the final payment status isn’t known when the `PaymentSheet` completes, and instead succeeds or fails later. If you support these types of payment methods, inform the customer their order is confirmed and only fulfill their order (for example, ship their product) when the payment is successful. # Android > This is a Android for when platform is android and mobile-ui is payment-element. View the full page at https://docs.stripe.com/payments/mobile/save-during-payment?platform=android&mobile-ui=payment-element. Use the [Payment Intents API](https://docs.stripe.com/api/payment_intents.md) to save payment details from a purchase. There are several use cases: - Charge a customer for an e-commerce order and store the details for future purchases. - Initiate the first payment of a series of recurring payments. - Charge a deposit and store the details to charge the full amount later. > #### Card-present transactions > > Card-present transactions, such as payments through Stripe Terminal, use a different process for saving the payment method. For details, see [the Terminal documentation](https://docs.stripe.com/terminal/features/saving-payment-details/save-after-payment.md). ## Compliance You’re responsible for your compliance with all applicable laws, regulations, and network rules when saving a customer’s payment details for future use, such as displaying a customer’s payment method to them in the checkout flow for a future purchase or charging them when they’re not actively using your website or app. Before saving or charging a customer’s payment mathod, make sure you: - Add terms to your website or app that state how you plan to save payment method details, such as: - The customer’s agreement allowing you to initiate a payment or a series of payments on their behalf for specified transactions. - The anticipated timing and frequency of payments (for example, if the charges are for scheduled installments, subscription payments, or unscheduled top-ups). - How you determine the payment amount. - Your cancellation policy, if the payment method is for a subscription service. - Use a saved payment method for only the purpose stated in your terms. - Collect explicit consent from the customer for this specific use. For example, include a "Save my payment method for future checkbox. - Keep a record of your customer’s written agreement to your terms. ## Set up Stripe [Server-side] [Client-side] First, you need a Stripe account. [Register now](https://dashboard.stripe.com/register). ### Server-side This integration requires endpoints on your server that talk to the Stripe API. Use the official libraries for access to the Stripe API from your server: #### Ruby ```bash # Available as a gem sudo gem install stripe ``` ```ruby # If you use bundler, you can add this line to your Gemfile gem 'stripe' ``` ### Client-side The [Stripe Android SDK](https://github.com/stripe/stripe-android) is open source and [fully documented](https://stripe.dev/stripe-android/). To install the SDK, add `stripe-android` to the `dependencies` block of your [app/build.gradle](https://developer.android.com/studio/build/dependencies) file: #### Kotlin ```kotlin plugins { id("com.android.application") } android { ... } dependencies { // ... // Stripe Android SDK implementation("com.stripe:stripe-android:23.1.0") // Include the financial connections SDK to support US bank account as a payment method implementation("com.stripe:financial-connections:23.1.0") } ``` > For details on the latest SDK release and past versions, see the [Releases](https://github.com/stripe/stripe-android/releases) page on GitHub. To receive notifications when a new release is published, [watch releases for the repository](https://docs.github.com/en/github/managing-subscriptions-and-notifications-on-github/configuring-notifications#configuring-your-watch-settings-for-an-individual-repository). ## Enable payment methods Card payments are enabled by default. View your [payment methods settings](https://dashboard.stripe.com/settings/payment_methods) to enable more payment methods you want to support. ## Add an endpoint [Server-side] > #### Note > > To display the PaymentSheet before you create a PaymentIntent, see [Collect payment details before creating an Intent](https://docs.stripe.com/payments/accept-a-payment-deferred.md?type=payment). If your Connect platform uses [customer-configured Accounts](https://docs.stripe.com/api/v2/core/accounts/create.md#v2_create_accounts-configuration-customer), use our [guide](https://docs.stripe.com/connect/use-accounts-as-customers.md) to replace `Customer` and event references in your code with the equivalent Accounts v2 API references. This integration uses three Stripe API objects: 1. [PaymentIntent](https://docs.stripe.com/api/payment_intents.md): Stripe uses this to represent your intent to collect payment from a customer, tracking your charge attempts and payment state changes throughout the process. 1. [Customer](https://docs.stripe.com/api/customers.md): To set up a payment method for future payments, you must attach it to a *Customer* (Customer objects represent customers of your business. They let you reuse payment methods and give you the ability to track multiple payments). Create a Customer object when your customer creates an account with your business. If your customer is making a payment as a guest, you can create a Customer object before payment and associate it with your own internal representation of the customer’s account later. 1. [CustomerSession](https://docs.stripe.com/api/customer_sessions.md): Information on the Customer object is sensitive, and can’t be retrieved directly from an app. A CustomerSession grants the SDK temporary scoped access to the Customer and provides additional configuration options. See a complete list of [configuration options](https://docs.stripe.com/api/customer_sessions/create.md#create_customer_session-components). For security reasons, your app can’t create these objects. Instead, add an endpoint on your server that: 1. Retrieves the Customer, or creates a new one. 1. Creates a [CustomerSession](https://docs.stripe.com/api/customer_sessions.md) for the Customer. 1. Creates a PaymentIntent with the [amount](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-amount), [currency](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-currency), and [customer](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-customer), [setup_future_usage](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-setup_future_usage) . 1. Returns the Payment Intent’s *client secret* (The client secret is a unique key returned from Stripe as part of a PaymentIntent. This key lets the client access important fields from the PaymentIntent (status, amount, currency) while hiding sensitive ones (metadata, customer)), the CustomerSession’s `client_secret`, the Customer’s [id](https://docs.stripe.com/api/customers/object.md#customer_object-id), and your [publishable key](https://dashboard.stripe.com/apikeys) to your app. > The mobile Payment Element only supports `setup_future_usage` with cards and US bank accounts. The payment methods shown to customers during the checkout process are also included on the PaymentIntent. You can let Stripe pull payment methods from your Dashboard settings or you can list them manually. Regardless of the option you choose, know that the currency passed in the PaymentIntent filters the payment methods shown to the customer. For example, if you pass `eur` on the PaymentIntent and have OXXO enabled in the Dashboard, OXXO won’t be shown to the customer because OXXO doesn’t support `eur` payments. Unless your integration requires a code-based option for offering payment methods, Stripe recommends the automated option. This is because Stripe evaluates the currency, payment method restrictions, and other parameters to determine the list of supported payment methods. Payment methods that increase conversion and that are most relevant to the currency and customer’s location are prioritized. #### Manage payment methods from the Dashboard You can manage payment methods from the [Dashboard](https://dashboard.stripe.com/settings/payment_methods). Stripe handles the return of eligible payment methods based on factors such as the transaction’s amount, currency, and payment flow. The PaymentIntent is created using the payment methods you configured in the Dashboard. If you don’t want to use the Dashboard or if you want to specify payment methods manually, you can list them using the `payment_method_types` attribute. #### curl ```bash # Create a Customer (use an existing Customer ID if this is a returning customer) curl https://api.stripe.com/v1/customers \ -u <>: \ -X "POST" \ -H "Stripe-Account: {{CONNECTED_ACCOUNT_ID}}" # Create an CustomerSession for the Customer curl https://api.stripe.com/v1/customer_sessions \ -u <>: \ -X "POST" \ -d "customer"="{{CUSTOMER_ID}}" \ -d "components[mobile_payment_element][enabled]"=true \ -d "components[mobile_payment_element][features][payment_method_save]"=enabled \ -d "components[mobile_payment_element][features][payment_method_redisplay]"=enabled \ -d "components[mobile_payment_element][features][payment_method_remove]"=enabled # Create a PaymentIntent curl https://api.stripe.com/v1/payment_intents \ -u <>: \ -X "POST" \ -d "customer"="{{CUSTOMER_ID}}" \ -d "amount"=1099 \ -d "currency"="eur" \ -d "setup_future_usage"="off_session" \ # In the latest version of the API, specifying the `automatic_payment_methods` parameter # is optional because Stripe enables its functionality by default. -d "automatic_payment_methods[enabled]"=true \ ``` #### Listing payment methods manually #### curl ```bash # Create a Customer (use an existing Customer ID if this is a returning customer) curl https://api.stripe.com/v1/customers \ -u <>: \ -X "POST" \ -H "Stripe-Account: {{CONNECTED_ACCOUNT_ID}}" # Create an CustomerSession for the Customer curl https://api.stripe.com/v1/customer_sessions \ -u <>: \ -X "POST" \ -d "customer"="{{CUSTOMER_ID}}" \ -d "components[mobile_payment_element][enabled]"=true \ -d "components[mobile_payment_element][features][payment_method_save]"=enabled \ -d "components[mobile_payment_element][features][payment_method_redisplay]"=enabled \ -d "components[mobile_payment_element][features][payment_method_remove]"=enabled # Create a PaymentIntent curl https://api.stripe.com/v1/payment_intents \ -u <>: \ -X "POST" \ -d "customer"="{{CUSTOMER_ID}}" \ -d "amount"=1099 \ -d "currency"="eur" \ -d "setup_future_usage"="off_session" \ -d "payment_method_types[]"="card" \ ``` > Each payment method needs to support the currency passed in the PaymentIntent and your business needs to be based in one of the countries each payment method supports. See the [Payment method integration options](https://docs.stripe.com/payments/payment-methods/integration-options.md) page for more details about what’s supported. ## Collect payment details [Client-side] Before displaying the mobile Payment Element, your checkout page should: - Show the products being purchased and the total amount - Collect any required shipping information using the [Address Element](https://docs.stripe.com/elements/address-element.md?platform=android) - Include a checkout button to present Stripe’s UI #### Jetpack Compose [Initialize](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/-builder/index.html) a `PaymentSheet` instance inside `onCreate` of your checkout Activity, passing a method to handle the result. ```kotlin import androidx.compose.runtime.Composable import androidx.compose.runtime.remember import com.stripe.android.paymentsheet.PaymentSheet import com.stripe.android.paymentsheet.PaymentSheetResult @Composable fun App() { val paymentSheet = remember { PaymentSheet.Builder(::onPaymentSheetResult) }.build() } private fun onPaymentSheetResult(paymentSheetResult: PaymentSheetResult) { // implemented in the next steps } ``` Next, fetch the PaymentIntent client secret, Customer Session client secret, Customer ID, and publishable key from the endpoint you created in the previous step. Set the publishable key using `PaymentConfiguration` and store the others for use when you present the PaymentSheet. ```kotlin import androidx.compose.runtime.Composable import androidx.compose.runtime.rememberimport androidx.compose.runtime.LaunchedEffect import androidx.compose.runtime.getValue import androidx.compose.runtime.mutableStateOf import androidx.compose.runtime.setValue import androidx.compose.ui.platform.LocalContext import com.stripe.android.PaymentConfiguration import com.stripe.android.paymentsheet.PaymentSheet import com.stripe.android.paymentsheet.PaymentSheetResult @Composable fun App() { val paymentSheet = remember { PaymentSheet.Builder(::onPaymentSheetResult) }.build()val context = LocalContext.current var customerConfig by remember { mutableStateOf(null) } varpaymentIntentClientSecret by remember { mutableStateOf(null) } LaunchedEffect(context) { // Make a request to your own server and retrieve payment configurations val networkResult = ... if (networkResult.isSuccess) {paymentIntentClientSecret = networkResult.paymentIntent customerConfig = PaymentSheet.CustomerConfiguration.createWithCustomerSession( id = networkResult.customer, clientSecret = networkResult.customerSessionClientSecret )PaymentConfiguration.init(context, networkResult.publishableKey)} } } private fun onPaymentSheetResult(paymentSheetResult: PaymentSheetResult) { // implemented in the next steps } ``` When the customer taps your checkout button, call [presentWithPaymentIntent](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/index.html#1814490530%2FFunctions%2F2002900378) to present the payment sheet. After the customer completes the payment, the sheet dismisses and the [PaymentSheetResultCallback](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet-result-callback/index.html) is called with a [PaymentSheetResult](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet-result/index.html). ```kotlin import androidx.compose.material.Button import androidx.compose.material.Text import androidx.compose.runtime.Composable import androidx.compose.runtime.LaunchedEffect import androidx.compose.runtime.getValue import androidx.compose.runtime.mutableStateOf import androidx.compose.runtime.remember import androidx.compose.runtime.setValue import androidx.compose.ui.platform.LocalContext import com.stripe.android.PaymentConfiguration import com.stripe.android.paymentsheet.PaymentSheet import com.stripe.android.paymentsheet.PaymentSheetResult @Composable fun App() { val paymentSheet = remember { PaymentSheet.Builder(::onPaymentSheetResult) }.build() val context = LocalContext.current var customerConfig by remember { mutableStateOf(null) } var paymentIntentClientSecret by remember { mutableStateOf(null) } LaunchedEffect(context) { // Make a request to your own server and retrieve payment configurations val networkResult = ... if (networkResult.isSuccess) { paymentIntentClientSecret = networkResult.paymentIntent customerConfig = PaymentSheet.CustomerConfiguration.createWithCustomerSession( id = networkResult.customer, clientSecret = networkResult.customerSessionClientSecret ) PaymentConfiguration.init(context, networkResult.publishableKey) } }Button( onClick = { val currentConfig = customerConfig val currentClientSecret =paymentIntentClientSecret if (currentConfig != null && currentClientSecret != null) { presentPaymentSheet(paymentSheet, currentConfig, currentClientSecret) } } ) { Text("Checkout") } }private fun presentPaymentSheet( paymentSheet: PaymentSheet, customerConfig: PaymentSheet.CustomerConfiguration,paymentIntentClientSecret: String ) { paymentSheet.presentWithPaymentIntent(paymentIntentClientSecret, PaymentSheet.Configuration.Builder(merchantDisplayName = "My merchant name") .customer(customerConfig) // Set `allowsDelayedPaymentMethods` to true if your business handles // delayed notification payment methods like US bank accounts. .allowsDelayedPaymentMethods(true) .build() ) } private fun onPaymentSheetResult(paymentSheetResult: PaymentSheetResult) {when(paymentSheetResult) { is PaymentSheetResult.Canceled -> { print("Canceled") } is PaymentSheetResult.Failed -> { print("Error: ${paymentSheetResult.error}") } is PaymentSheetResult.Completed -> { // Display for example, an order confirmation screen print("Completed") } } } ``` #### Views (Classic) [Initialize](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/index.html#-394860221%2FConstructors%2F2002900378) a `PaymentSheet` instance inside `onCreate` of your checkout Activity, passing a method to handle the result. #### Kotlin ```kotlin import com.stripe.android.paymentsheet.PaymentSheet class CheckoutActivity : AppCompatActivity() { lateinit var paymentSheet: PaymentSheet override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) paymentSheet = PaymentSheet.Builder(::onPaymentSheetResult).build(this) } fun onPaymentSheetResult(paymentSheetResult: PaymentSheetResult) { // implemented in the next steps } } ``` Next, fetch the PaymentIntent client secret, Customer Session client secret, Customer ID, and publishable key from the endpoint you created in the previous step.

After the customer completes the payment, the sheet dismisses and the [PaymentSheetResultCallback](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet-result-callback/index.html) is called with a [PaymentSheetResult](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet-result/index.html). #### Kotlin ```kotlin // ... class CheckoutActivity : AppCompatActivity() { lateinit var paymentSheet: PaymentSheet lateinit var customerConfig: PaymentSheet.CustomerConfiguration lateinit var paymentIntentClientSecret: String // ...fun presentPaymentSheet() { paymentSheet.presentWithPaymentIntent(paymentIntentClientSecret, PaymentSheet.Configuration.Builder(merchantDisplayName = "My merchant name") .customer(customerConfig) // Set `allowsDelayedPaymentMethods` to true if your business handles // delayed notification payment methods like US bank accounts. .allowsDelayedPaymentMethods(true) .build() ) } fun onPaymentSheetResult(paymentSheetResult: PaymentSheetResult) {when(paymentSheetResult) { is PaymentSheetResult.Canceled -> { print("Canceled") } is PaymentSheetResult.Failed -> { print("Error: ${paymentSheetResult.error}") } is PaymentSheetResult.Completed -> { // Display for example, an order confirmation screen print("Completed") } } } } ``` Setting `allowsDelayedPaymentMethods` to true allows [delayed notification](https://docs.stripe.com/payments/payment-methods.md#payment-notification) payment methods like US bank accounts. For these payment methods, the final payment status isn’t known when the `PaymentSheet` completes, and instead succeeds or fails later. If you support these types of payment methods, inform the customer their order is confirmed and only fulfill their order (for example, ship their product) when the payment is successful. ## Handle post-payment events [Server-side] Stripe sends a [payment_intent.succeeded](https://docs.stripe.com/api/events/types.md#event_types-payment_intent.succeeded) event when the payment completes. Use the [Dashboard webhook tool](https://dashboard.stripe.com/webhooks) or follow the [webhook guide](https://docs.stripe.com/webhooks/quickstart.md) to receive these events and run actions, such as sending an order confirmation email to your customer, logging the sale in a database, or starting a shipping workflow. Listen for these events rather than waiting on a callback from the client. On the client, the customer could close the browser window or quit the app before the callback executes, and malicious clients could manipulate the response. Setting up your integration to listen for asynchronous events is what enables you to accept [different types of payment methods](https://stripe.com/payments/payment-methods-guide) with a single integration. In addition to handling the `payment_intent.succeeded` event, we recommend handling these other events when collecting payments with the Payment Element: | Event | Description | Action | | ------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | [payment_intent.succeeded](https://docs.stripe.com/api/events/types.md?lang=php#event_types-payment_intent.succeeded) | Sent when a customer successfully completes a payment. | Send the customer an order confirmation and *fulfill* (Fulfillment is the process of providing the goods or services purchased by a customer, typically after payment is collected) their order. | | [payment_intent.processing](https://docs.stripe.com/api/events/types.md?lang=php#event_types-payment_intent.processing) | Sent when a customer successfully initiates a payment, but the payment has yet to complete. This event is most commonly sent when the customer initiates a bank debit. It’s followed by either a `payment_intent.succeeded` or `payment_intent.payment_failed` event in the future. | Send the customer an order confirmation that indicates their payment is pending. For digital goods, you might want to fulfill the order before waiting for payment to complete. | | [payment_intent.payment_failed](https://docs.stripe.com/api/events/types.md?lang=php#event_types-payment_intent.payment_failed) | Sent when a customer attempts a payment, but the payment fails. | If a payment transitions from `processing` to `payment_failed`, offer the customer another attempt to pay. | ## Charge the saved Payment Method later [Server-side] > #### Compliance > > You’re responsible for your compliance with all applicable laws, regulations, and network rules when saving a customer’s payment details. When rendering past payment methods to your end customer for future purchases, make sure you’re listing payment methods where you’ve collected consent from the customer to save the payment method details for this specific future use. To differentiate between payment methods attached to customers that can and can’t be presented to your end customer as a saved payment method for future purchases, use the [allow_redisplay](https://docs.stripe.com/api/payment_methods/object.md#payment_method_object-allow_redisplay) parameter. When you’re ready to charge your customer *off-session* (A payment is described as off-session if it occurs without the direct involvement of the customer, using previously-collected payment information), use the Customer and PaymentMethod IDs to create a PaymentIntent. To find a payment method to charge, list the payment methods associated with your customer. This example lists cards but you can list any supported [type](https://docs.stripe.com/api/payment_methods/object.md#payment_method_object-type). ```curl curl -G https://api.stripe.com/v1/payment_methods \ -u "<>:" \ -d "customer={{CUSTOMER_ID}}" \ -d type=card ``` When you have the Customer and PaymentMethod IDs, create a PaymentIntent with the amount and currency of the payment. Set a few other parameters to make the off-session payment: - Set [off_session](https://docs.stripe.com/api/payment_intents/confirm.md#confirm_payment_intent-off_session) to `true` to indicate that the customer isn’t in your checkout flow during a payment attempt and can’t fulfill an authentication request made by a partner, such as a card issuer, bank, or other payment institution. If, during your checkout flow, a partner requests authentication, Stripe requests exemptions using customer information from a previous *on-session* (A payment is described as on-session if it occurs while the customer is actively in your checkout flow and able to authenticate the payment method) transaction. If the conditions for exemption aren’t met, the PaymentIntent might throw an error. - Set the value of the PaymentIntent’s [confirm](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-confirm) property to `true`, which causes confirmation to occur immediately when the PaymentIntent is created. - Set [payment_method](https://docs.stripe.com/api.md#create_payment_intent-payment_method) to the ID of the PaymentMethod and [customer](https://docs.stripe.com/api.md#create_payment_intent-customer) to the ID of the Customer. #### curl ```bash curl https://api.stripe.com/v1/payment_intents \ -u <>: \ -d amount=1099 \ -d currency=usd \ # In the latest version of the API, specifying the `automatic_payment_methods` parameter is optional because Stripe enables its functionality by default. -d "automatic_payment_methods[enabled]"=true \-d customer="{{CUSTOMER_ID}}" \ -d payment_method="{{PAYMENT_METHOD_ID}}" \ -d return_url="https://example.com/order/123/complete" \ -d off_session=true \ -d confirm=true ``` ## Test the integration #### Cards | Payment method | Scenario | How to test | | -------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------- | | Credit card | The card setup succeeds and doesn’t require *authentication* (Strong Customer Authentication (SCA) is a regulatory requirement in effect as of September 14, 2019, that impacts many European online payments. It requires customers to use two-factor authentication like 3D Secure to verify their purchase). | Fill out the credit card form using the credit card number `4242 4242 4242 4242` with any expiration, CVC, and postal code. | | Credit card | The card requires authentication for the initial setup, then succeeds for subsequent payments. | Fill out the credit card form using the credit card number `4000 0025 0000 3155` with any expiration, CVC, and postal code. | | Credit card | The card requires authentication for the initial setup and also requires authentication for subsequent payments. | Fill out the credit card form using the credit card number `4000 0027 6000 3184` with any expiration, CVC, and postal code. | | Credit card | The card is declined during setup. | Fill out the credit card form using the credit card number `4000 0000 0000 9995` with any expiration, CVC, and postal code. | ## Optional: Enable Google Pay ### Set up your integration To use Google Pay, first enable the Google Pay API by adding the following to the `` tag of your **AndroidManifest.xml**: ```xml ... ``` For more details, see Google Pay’s [Set up Google Pay API](https://developers.google.com/pay/api/android/guides/setup) for Android. ### Add Google Pay To add Google Pay to your integration, pass a [PaymentSheet.GooglePayConfiguration](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/-google-pay-configuration/index.html) with your Google Pay environment (production or test) and the [country code of your business](https://dashboard.stripe.com/settings/account) when initializing [PaymentSheet.Configuration](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/-configuration/index.html). #### Kotlin ```kotlin val googlePayConfiguration = PaymentSheet.GooglePayConfiguration( environment = PaymentSheet.GooglePayConfiguration.Environment.Test, countryCode = "US", currencyCode = "USD" // Required for Setup Intents, optional for Payment Intents ) val configuration = PaymentSheet.Configuration.Builder(merchantDisplayName = "My merchant name") .googlePay(googlePayConfiguration) .build() ``` ### Test Google Pay Google allows you to make test payments through their [Test card suite](https://developers.google.com/pay/api/android/guides/resources/test-card-suite). The test suite supports using Stripe [test cards](https://docs.stripe.com/testing.md). You must test Google Pay using a physical Android device instead of a simulated device, in a country where Google Pay is supported. Log in to a Google account on your test device with a real card saved to Google Wallet. ## Optional: Customize the sheet All customization is configured using the [PaymentSheet.Configuration](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/-configuration/index.html) object. ### Appearance Customize colors, fonts, and more to match the look and feel of your app by using the [appearance API](https://docs.stripe.com/elements/appearance-api/mobile.md?platform=android). ### Payment method layout Configure the layout of payment methods in the sheet using [paymentMethodLayout](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/-configuration/-builder/index.html#2123253356%2FFunctions%2F2002900378). You can display them horizontally, vertically, or let Stripe optimize the layout automatically. ![](https://b.stripecdn.com/docs-statics-srv/assets/android-mpe-payment-method-layouts.3bcfe828ceaad1a94e0572a22d91733f.png) #### Kotlin ```kotlin PaymentSheet.Configuration.Builder("Example, Inc.") .paymentMethodLayout(PaymentSheet.PaymentMethodLayout.Automatic) .build() ``` ### Collect users addresses Collect local and international shipping or billing addresses from your customers using the [Address Element](https://docs.stripe.com/elements/address-element.md?platform=android). ### Business display name Specify a customer-facing business name by setting [merchantDisplayName](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/-configuration/index.html#-191101533%2FProperties%2F2002900378). By default, this is your app’s name. #### Kotlin ```kotlin PaymentSheet.Configuration.Builder( merchantDisplayName = "My app, Inc." ).build() ``` ### Dark mode By default, `PaymentSheet` automatically adapts to the user’s system-wide appearance settings (light and dark mode). You can change this by setting light or dark mode on your app: #### Kotlin ```kotlin // force dark AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES) // force light AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_NO) ``` ### Default billing details To set default values for billing details collected in the payment sheet, configure the `defaultBillingDetails` property. The `PaymentSheet` pre-populates its fields with the values that you provide. #### Kotlin ```kotlin val address = PaymentSheet.Address(country = "US") val billingDetails = PaymentSheet.BillingDetails( address = address, email = "foo@bar.com" ) val configuration = PaymentSheet.Configuration.Builder(merchantDisplayName = "Merchant, Inc.") .defaultBillingDetails(billingDetails) .build() ``` ### Configure collection of billing details Use `BillingDetailsCollectionConfiguration` to specify how you want to collect billing details in the PaymentSheet. You can collect your customer’s name, email, phone number, and address. If you want to attach default billing details to the PaymentMethod object even when those fields aren’t collected in the UI, set `billingDetailsCollectionConfiguration.attachDefaultsToPaymentMethod` to `true`. #### Kotlin ```kotlin val billingDetails = PaymentSheet.BillingDetails( email = "foo@bar.com" ) val billingDetailsCollectionConfiguration = BillingDetailsCollectionConfiguration( attachDefaultsToPaymentMethod = true, name = BillingDetailsCollectionConfiguration.CollectionMode.Always, email = BillingDetailsCollectionConfiguration.CollectionMode.Never, address = BillingDetailsCollectionConfiguration.AddressCollectionMode.Full, ) val configuration = PaymentSheet.Configuration.Builder(merchantDisplayName = "Merchant, Inc.") .defaultBillingDetails(billingDetails) .billingDetailsCollectionConfiguration(billingDetailsCollectionConfiguration) .build() ``` > Consult with your legal counsel regarding laws that apply to collecting information. Only collect phone numbers if you need them for the transaction. ## Optional: Complete payment in your UI You can present Payment Sheet to only collect payment method details and complete the payment back in your app’s UI. This is useful if you have a custom buy button or require additional steps after payment details are collected. ![](https://b.stripecdn.com/docs-statics-srv/assets/android-multi-step.84d8a0a44b1baa596bda491322b6d9fd.png) > A sample integration is [available on our GitHub](https://github.com/stripe/stripe-android/blob/master/paymentsheet-example/src/main/java/com/stripe/android/paymentsheet/example/samples/ui/paymentsheet/custom_flow/CustomFlowActivity.kt). 1. First, initialize [PaymentSheet.FlowController](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/-flow-controller/index.html) instead of `PaymentSheet` using one of the [Builder](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/-flow-controller/-builder/index.html) methods. #### Android (Kotlin) ```kotlin class CheckoutActivity : AppCompatActivity() { private lateinit var flowController: PaymentSheet.FlowController override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) val flowController = PaymentSheet.FlowController.Builder( resultCallback = ::onPaymentSheetResult, paymentOptionResultCallback = ::onPaymentOption, ).build(this) } } ``` 1. Next, call `configureWithPaymentIntent` with the Stripe object keys fetched from your backend and update your UI in the callback using [getPaymentOption()](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/-flow-controller/index.html#-2091462043%2FFunctions%2F2002900378). This contains an image and label representing the customer’s currently selected payment method. #### Android (Kotlin) ```kotlin flowController.configureWithPaymentIntent( paymentIntentClientSecret = paymentIntentClientSecret, configuration = PaymentSheet.Configuration.Builder("Example, Inc.") .customer(PaymentSheet.CustomerConfiguration( id = customerId, ephemeralKeySecret = ephemeralKeySecret )) .build() ) { isReady, error -> if (isReady) { // Update your UI using `flowController.getPaymentOption()` } else { // handle FlowController configuration failure } } ``` 1. Next, call [presentPaymentOptions](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/-flow-controller/index.html#449924733%2FFunctions%2F2002900378) to collect payment details. When the customer finishes, the sheet is dismissed and calls the [paymentOptionCallback](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-option-callback/index.html) passed earlier in `create`. Implement this method to update your UI with the returned `paymentOption`. #### Android (Kotlin) ```kotlin // ... flowController.presentPaymentOptions() // ... private fun onPaymentOption(paymentOptionResult: PaymentOptionResult) { val paymentOption = paymentOptionResult.paymentOption if (paymentOption != null) { paymentMethodButton.text = paymentOption.label paymentMethodButton.setCompoundDrawablesRelativeWithIntrinsicBounds( paymentOption.drawableResourceId, 0, 0, 0 ) } else { paymentMethodButton.text = "Select" paymentMethodButton.setCompoundDrawablesRelativeWithIntrinsicBounds( null, null, null, null ) } } ``` 1. Finally, call [confirm](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/-flow-controller/index.html#-479056656%2FFunctions%2F2002900378) to complete the payment. When the customer finishes, the sheet is dismissed and calls the [paymentResultCallback](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet-result-callback/index.html#237248767%2FFunctions%2F2002900378) passed earlier in `create`. #### Android (Kotlin) ```kotlin // ... flowController.confirmPayment() // ... private fun onPaymentSheetResult( paymentSheetResult: PaymentSheetResult ) { when (paymentSheetResult) { is PaymentSheetResult.Canceled -> { // Payment canceled } is PaymentSheetResult.Failed -> { // Payment Failed. See logcat for details or inspect paymentSheetResult.error } is PaymentSheetResult.Completed -> { // Payment Complete } } } ``` Setting `allowsDelayedPaymentMethods` to true allows [delayed notification](https://docs.stripe.com/payments/payment-methods.md#payment-notification) payment methods like US bank accounts. For these payment methods, the final payment status isn’t known when the `PaymentSheet` completes, and instead succeeds or fails later. If you support these types of payment methods, inform the customer their order is confirmed and only fulfill their order (for example, ship their product) when the payment is successful. # React Native > This is a React Native for when platform is react-native and mobile-ui is payment-element. View the full page at https://docs.stripe.com/payments/mobile/save-during-payment?platform=react-native&mobile-ui=payment-element. Use the [Payment Intents API](https://docs.stripe.com/api/payment_intents.md) to save payment details from a purchase. There are several use cases: - Charge a customer for an e-commerce order and store the details for future purchases. - Initiate the first payment of a series of recurring payments. - Charge a deposit and store the details to charge the full amount later. > #### Card-present transactions > > Card-present transactions, such as payments through Stripe Terminal, use a different process for saving the payment method. For details, see [the Terminal documentation](https://docs.stripe.com/terminal/features/saving-payment-details/save-after-payment.md). ## Compliance You’re responsible for your compliance with all applicable laws, regulations, and network rules when saving a customer’s payment details for future use, such as displaying a customer’s payment method to them in the checkout flow for a future purchase or charging them when they’re not actively using your website or app. Before saving or charging a customer’s payment mathod, make sure you: - Add terms to your website or app that state how you plan to save payment method details, such as: - The customer’s agreement allowing you to initiate a payment or a series of payments on their behalf for specified transactions. - The anticipated timing and frequency of payments (for example, if the charges are for scheduled installments, subscription payments, or unscheduled top-ups). - How you determine the payment amount. - Your cancellation policy, if the payment method is for a subscription service. - Use a saved payment method for only the purpose stated in your terms. - Collect explicit consent from the customer for this specific use. For example, include a "Save my payment method for future checkbox. - Keep a record of your customer’s written agreement to your terms. ## Set up Stripe [Server-side] [Client-side] First, you need a Stripe account. [Register now](https://dashboard.stripe.com/register). ### Server-side This integration requires endpoints on your server that talk to the Stripe API. Use the official libraries for access to the Stripe API from your server: #### Ruby ```bash # Available as a gem sudo gem install stripe ``` ```ruby # If you use bundler, you can add this line to your Gemfile gem 'stripe' ``` ### Client-side The [React Native SDK](https://github.com/stripe/stripe-react-native) is open source and fully documented. Internally, it uses the [native iOS](https://github.com/stripe/stripe-ios) and [Android](https://github.com/stripe/stripe-android) SDKs. To install Stripe’s React Native SDK, run one of the following commands in your project’s directory (depending on which package manager you use): #### yarn ```bash yarn add @stripe/stripe-react-native ``` #### npm ```bash npm install @stripe/stripe-react-native ``` Next, install some other necessary dependencies: - For iOS, go to the **ios** directory and run `pod install` to ensure that you also install the required native dependencies. - For Android, there are no more dependencies to install. > We recommend following the [official TypeScript guide](https://reactnative.dev/docs/typescript#adding-typescript-to-an-existing-project) to add TypeScript support. ### Stripe initialization To initialize Stripe in your React Native app, either wrap your payment screen with the `StripeProvider` component, or use the `initStripe` initialization method. Only the API [publishable key](https://docs.stripe.com/keys.md#obtain-api-keys) in `publishableKey` is required. The following example shows how to initialize Stripe using the `StripeProvider` component. ```jsx import { useState, useEffect } from 'react'; import { StripeProvider } from '@stripe/stripe-react-native'; function App() { const [publishableKey, setPublishableKey] = useState(''); const fetchPublishableKey = async () => { const key = await fetchKey(); // fetch key from your server here setPublishableKey(key); }; useEffect(() => { fetchPublishableKey(); }, []); return ( {/* Your app code here */} ); } ``` > Use your API [test keys](https://docs.stripe.com/keys.md#obtain-api-keys) while you test and develop, and your [live mode](https://docs.stripe.com/keys.md#test-live-modes) keys when you publish your app. ## Enable payment methods Card payments are enabled by default. View your [payment methods settings](https://dashboard.stripe.com/settings/payment_methods) to enable more payment methods you want to support. ## Add an endpoint [Server-side] > #### Note > > To display the PaymentSheet before you create a PaymentIntent, see [Collect payment details before creating an Intent](https://docs.stripe.com/payments/accept-a-payment-deferred.md?type=payment). If your Connect platform uses [customer-configured Accounts](https://docs.stripe.com/api/v2/core/accounts/create.md#v2_create_accounts-configuration-customer), use our [guide](https://docs.stripe.com/connect/use-accounts-as-customers.md) to replace `Customer` and event references in your code with the equivalent Accounts v2 API references. This integration uses three Stripe API objects: 1. [PaymentIntent](https://docs.stripe.com/api/payment_intents.md): Stripe uses this to represent your intent to collect payment from a customer, tracking your charge attempts and payment state changes throughout the process. 1. [Customer](https://docs.stripe.com/api/customers.md): To set up a payment method for future payments, you must attach it to a *Customer* (Customer objects represent customers of your business. They let you reuse payment methods and give you the ability to track multiple payments). Create a Customer object when your customer creates an account with your business. If your customer is making a payment as a guest, you can create a Customer object before payment and associate it with your own internal representation of the customer’s account later. 1. [CustomerSession](https://docs.stripe.com/api/customer_sessions.md): Information on the Customer object is sensitive, and can’t be retrieved directly from an app. A CustomerSession grants the SDK temporary scoped access to the Customer and provides additional configuration options. See a complete list of [configuration options](https://docs.stripe.com/api/customer_sessions/create.md#create_customer_session-components). For security reasons, your app can’t create these objects. Instead, add an endpoint on your server that: 1. Retrieves the Customer, or creates a new one. 1. Creates a [CustomerSession](https://docs.stripe.com/api/customer_sessions.md) for the Customer. 1. Creates a PaymentIntent with the [amount](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-amount), [currency](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-currency), and [customer](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-customer), [setup_future_usage](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-setup_future_usage) . 1. Returns the Payment Intent’s *client secret* (The client secret is a unique key returned from Stripe as part of a PaymentIntent. This key lets the client access important fields from the PaymentIntent (status, amount, currency) while hiding sensitive ones (metadata, customer)), the CustomerSession’s `client_secret`, the Customer’s [id](https://docs.stripe.com/api/customers/object.md#customer_object-id), and your [publishable key](https://dashboard.stripe.com/apikeys) to your app. > The mobile Payment Element only supports `setup_future_usage` with cards and US bank accounts. The payment methods shown to customers during the checkout process are also included on the PaymentIntent. You can let Stripe pull payment methods from your Dashboard settings or you can list them manually. Regardless of the option you choose, know that the currency passed in the PaymentIntent filters the payment methods shown to the customer. For example, if you pass `eur` on the PaymentIntent and have OXXO enabled in the Dashboard, OXXO won’t be shown to the customer because OXXO doesn’t support `eur` payments. Unless your integration requires a code-based option for offering payment methods, Stripe recommends the automated option. This is because Stripe evaluates the currency, payment method restrictions, and other parameters to determine the list of supported payment methods. Payment methods that increase conversion and that are most relevant to the currency and customer’s location are prioritized. #### Manage payment methods from the Dashboard You can manage payment methods from the [Dashboard](https://dashboard.stripe.com/settings/payment_methods). Stripe handles the return of eligible payment methods based on factors such as the transaction’s amount, currency, and payment flow. The PaymentIntent is created using the payment methods you configured in the Dashboard. If you don’t want to use the Dashboard or if you want to specify payment methods manually, you can list them using the `payment_method_types` attribute. #### curl ```bash # Create a Customer (use an existing Customer ID if this is a returning customer) curl https://api.stripe.com/v1/customers \ -u <>: \ -X "POST" \ -H "Stripe-Account: {{CONNECTED_ACCOUNT_ID}}" # Create an CustomerSession for the Customer curl https://api.stripe.com/v1/customer_sessions \ -u <>: \ -X "POST" \ -d "customer"="{{CUSTOMER_ID}}" \ -d "components[mobile_payment_element][enabled]"=true \ -d "components[mobile_payment_element][features][payment_method_save]"=enabled \ -d "components[mobile_payment_element][features][payment_method_redisplay]"=enabled \ -d "components[mobile_payment_element][features][payment_method_remove]"=enabled # Create a PaymentIntent curl https://api.stripe.com/v1/payment_intents \ -u <>: \ -X "POST" \ -d "customer"="{{CUSTOMER_ID}}" \ -d "amount"=1099 \ -d "currency"="eur" \ -d "setup_future_usage"="off_session" \ # In the latest version of the API, specifying the `automatic_payment_methods` parameter # is optional because Stripe enables its functionality by default. -d "automatic_payment_methods[enabled]"=true \ ``` #### Listing payment methods manually #### curl ```bash # Create a Customer (use an existing Customer ID if this is a returning customer) curl https://api.stripe.com/v1/customers \ -u <>: \ -X "POST" \ -H "Stripe-Account: {{CONNECTED_ACCOUNT_ID}}" # Create an CustomerSession for the Customer curl https://api.stripe.com/v1/customer_sessions \ -u <>: \ -X "POST" \ -d "customer"="{{CUSTOMER_ID}}" \ -d "components[mobile_payment_element][enabled]"=true \ -d "components[mobile_payment_element][features][payment_method_save]"=enabled \ -d "components[mobile_payment_element][features][payment_method_redisplay]"=enabled \ -d "components[mobile_payment_element][features][payment_method_remove]"=enabled # Create a PaymentIntent curl https://api.stripe.com/v1/payment_intents \ -u <>: \ -X "POST" \ -d "customer"="{{CUSTOMER_ID}}" \ -d "amount"=1099 \ -d "currency"="eur" \ -d "setup_future_usage"="off_session" \ -d "payment_method_types[]"="card" \ ``` > Each payment method needs to support the currency passed in the PaymentIntent and your business needs to be based in one of the countries each payment method supports. See the [Payment method integration options](https://docs.stripe.com/payments/payment-methods/integration-options.md) page for more details about what’s supported. ## Collect payment details [Client-side] Before displaying the mobile Payment Element, your checkout page should: - Show the products being purchased and the total amount - Collect any required shipping information - Include a checkout button to present Stripe’s UI In the checkout of your app, make a network request to the backend endpoint you created in the previous step and call `initPaymentSheet` from the `useStripe` hook. ```javascript export default function CheckoutScreen() { const { initPaymentSheet, presentPaymentSheet } = useStripe(); const [loading, setLoading] = useState(false); const fetchPaymentSheetParams = async () => { const response = await fetch(`${API_URL}/payment-sheet`, { method: 'POST', headers: { 'Content-Type': 'application/json', }, }); const { paymentIntent, ephemeralKey, customer } = await response.json(); return { paymentIntent, ephemeralKey, customer, }; }; const initializePaymentSheet = async () => { const { paymentIntent, ephemeralKey, customer, } = await fetchPaymentSheetParams(); const { error } = await initPaymentSheet({ merchantDisplayName: "Example, Inc.", customerId: customer, customerEphemeralKeySecret: ephemeralKey, paymentIntentClientSecret: paymentIntent, // Set `allowsDelayedPaymentMethods` to true if your business can handle payment //methods that complete payment after a delay, like SEPA Debit and Sofort. allowsDelayedPaymentMethods: true, defaultBillingDetails: { name: 'Jane Doe', } }); if (!error) { setLoading(true); } }; const openPaymentSheet = async () => { // see below }; useEffect(() => { initializePaymentSheet(); }, []); return (
