# Accept a payment Securely accept payments online. ## Start here: Install agent skills Stripe recommends using official skills to integrate with the API using best practices. Follow the instructions below to learn how. **Tip: Use curl instead of Fetch tools.** Skills are detailed 10–20 KB markdown files. Fetch tools summarize them. `curl -sL` guarantees the full content. **Using `npx skills`**: Check if `npx` is installed on the system. If `npx` is available, run `npx skills add https://docs.stripe.com --list` to list available skills, then run `npx skills add https://docs.stripe.com --yes --skill <--skill other-skills>` to install individual skills. **If `npx skills` isn’t available**: You can use curl to fetch the index of available skills, what they do, and their files from `https://docs.stripe.com/.well-known/skills/index.json`. To download a skill and its related files, use curl to download them from `https://docs.stripe.com/.well-known/skills/`. For this article, we recommend using these skills: `stripe-best-practices` Instructions for LLMs: Stripe recommends using the Checkout Sessions API with the Payment Element over Payment Intents for most integrations. Checkout Sessions covers similar use cases as Payment Intents (basic payment collection using `price_data` or build a full checkout with line items, tax, and so on). Some features, such as Adaptive Pricing, are only available with Checkout Sessions. Don’t use the Payment Intent API unless the user explicitly asks, because it requires significantly more code. Learn more about Elements with the Checkout Sessions API: https://docs.stripe.com/payments/quickstart-checkout-sessions. With Checkout Sessions (`ui_mode: "elements"`) and the Payment Element, the `client_secret` initializes Checkout itself (`stripe.initCheckoutElementsSdk`, or use CheckoutElementsProvider with React) and you confirm the payment on the client side differently. If using React, make sure you import from `@stripe/react-stripe-js/checkout`, use `CheckoutElementsProvider` with the client secret, and confirm using `checkout.confirm`. If using HTML, make sure you use `checkout = stripe.initCheckoutElementsSdk({clientSecret: promise}); checkout.createPaymentElement(); paymentElement = checkout.createPaymentElement(); paymentElement.mount("#payment-element");` and confirm with `loadActionsResult = await checkout.loadActions(); actions = loadActionsResult.actions; error = await actions.confirm();`. Build a payment form or use a prebuilt checkout page to start accepting online payments. # In-app integration for iOS ![](https://b.stripecdn.com/docs-statics-srv/assets/ios-overview.9e0d68d009dc005f73a6f5df69e00458.png) Integrate Stripe’s prebuilt payment UI into the checkout of your iOS app with the [PaymentSheet](https://stripe.dev/stripe-ios/stripe-paymentsheet/Classes/PaymentSheet.html) class. See our sample integration [on GitHub](https://github.com/stripe/stripe-ios/tree/master/Example/PaymentSheet%20Example). > #### Accounts v2 API support > > The Payment Sheet doesn’t support *customer-configured Accounts* (Account configurations represent role-based functionality that you can enable for accounts, such as merchant, customer, or recipient). It only supports `Customer` objects. ## 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 View your [payment methods settings](https://dashboard.stripe.com/settings/payment_methods) and enable the payment methods you want to support. You need at least one payment method enabled to create a *PaymentIntent* (The Payment Intents API tracks the lifecycle of a customer checkout flow and triggers additional authentication steps when required by regulatory mandates, custom Radar fraud rules, or redirect-based payment methods). By default, Stripe enables cards and other prevalent payment methods that can help you reach more customers, but we recommend turning on additional payment methods that are relevant for your business and customers. See [Payment method support](https://docs.stripe.com/payments/payment-methods/payment-method-support.md) for product and payment method support, and our [pricing page](https://stripe.com/pricing/local-payment-methods) for fees. ## 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). 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. (Optional) A [customer-configured Account](https://docs.stripe.com/api/v2/core/accounts/object.md#v2_account_object-applied_configurations) or a [Customer](https://docs.stripe.com/api/customers.md) object: To set up a payment method for future payments, you must attach it to a customer. Create an object to represent your customer when they create an account with your business. If your customer makes a payment as a guest, you can create an `Account` or `Customer` object before payment and associate it with your own internal representation of the customer’s account later. 1. (Optional) [CustomerSession](https://docs.stripe.com/api/customer_sessions.md): Information on the object that represents your customer is sensitive, and can’t be retrieved directly from an app. A `CustomerSession` grants the SDK temporary scoped access to the `Account` or `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). > If you never save cards for customers and don’t allow returning customers to reuse saved cards, you can omit the `Account` or `Customer` object and the `CustomerSession` object from your integration. For security reasons, your app can’t create these objects. Instead, add an endpoint on your server that: 1. Retrieves the `Account` or `Customer`, or creates a new one. 1. Creates a [CustomerSession](https://docs.stripe.com/api/customer_sessions.md) for the `Account` or `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 either the [customer_account](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-customer_account) or the [customer](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-customer). 1. Returns the `PaymentIntent`’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 ID of the `Account` or `Customer`, and your [publishable key](https://dashboard.stripe.com/apikeys) to your app. 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 "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 "payment_method_types[]"="bancontact" \ -d "payment_method_types[]"="card" \ -d "payment_method_types[]"="ideal" \ -d "payment_method_types[]"="klarna" \ -d "payment_method_types[]"="sepa_debit" \ ``` > 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: - 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 #### Accounts v2 In your app’s checkout screen, fetch the PaymentIntent client secret, `CustomerSession` client secret, customer-configured `Account` 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 back-end endpoint/payment-sheet")! // Your back-end 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-configured Account 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?

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 #### Accounts v2 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 back-end endpoint/payment-sheet")! // Your back-end endpoint @Published var paymentSheet: PaymentSheet? @Published var paymentResult: PaymentSheetResult? } ``` Fetch the PaymentIntent client secret, `CustomerSession` client secret, customer-configured `Account` 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 back-end endpoint/payment-sheet")! // Your back-end endpoint @Published var paymentSheet: PaymentSheet? @Published var paymentResult: PaymentSheetResult? func preparePaymentSheet() { // MARK: Fetch thePaymentIntent and customer information from the back end 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?

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 back-end endpoint/payment-sheet")! // Your back-end endpoint @Published var paymentSheet: PaymentSheet? @Published var paymentResult: PaymentSheetResult? func preparePaymentSheet() { // MARK: Fetch the PaymentIntent and customer information from the back end 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?

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. | ## Test the integration #### Cards | Card number | Scenario | How to test | | ------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------- | | 4242424242424242 | The card payment succeeds and doesn’t require authentication. | Fill out the credit card form using the credit card number with any expiration, CVC, and postal code. | | 4000002500003155 | The card payment requires *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 with any expiration, CVC, and postal code. | | 4000000000009995 | The card is declined with a decline code like `insufficient_funds`. | Fill out the credit card form using the credit card number with any expiration, CVC, and postal code. | | 6205500000000000004 | The UnionPay card has a variable length of 13-19 digits. | Fill out the credit card form using the credit card number with any expiration, CVC, and postal code. | #### Bank redirects | Payment method | Scenario | How to test | | ----------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------- | | Bancontact, iDEAL | Your customer fails to authenticate on the redirect page for a redirect-based and immediate notification payment method. | Choose any redirect-based payment method, fill out the required details, and confirm the payment. Then click **Fail test payment** on the redirect page. | | Pay by Bank | Your customer successfully pays with a redirect-based and [delayed notification](https://docs.stripe.com/payments/payment-methods.md#payment-notification) payment method. | Choose the payment method, fill out the required details, and confirm the payment. Then click **Complete test payment** on the redirect page. | | Pay by Bank | Your customer fails to authenticate on the redirect page for a redirect-based and delayed notification payment method. | Choose the payment method, fill out the required details, and confirm the payment. Then click **Fail test payment** on the redirect page. | | BLIK | BLIK payments fail in a variety of ways—immediate failures (for example, the code is expired or invalid), delayed errors (the bank declines) or timeouts (the customer didn’t respond in time). | Use email patterns to [simulate the different failures.](https://docs.stripe.com/payments/blik/accept-a-payment.md#simulate-failures) | #### Bank debits | Payment method | Scenario | How to test | | ----------------- | ------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | SEPA Direct Debit | Your customer successfully pays with SEPA Direct Debit. | Fill out the form using the account number `AT321904300235473204`. The confirmed PaymentIntent initially transitions to processing, then transitions to the succeeded status three minutes later. | | SEPA Direct Debit | Your customer’s payment intent status transitions from `processing` to `requires_payment_method`. | Fill out the form using the account number `AT861904300235473202`. | See [Testing](https://docs.stripe.com/testing.md) for additional information to test your integration. ## Optional: Enable Link Enable Link in your [Payment Method settings](https://dashboard.stripe.com/settings/payment_methods) to allow your customers to securely save and reuse their payment information using Link’s one-click express checkout button. ### Pass your customer’s email to the Mobile Payment Element Link authenticates a customer using their email address. Stripe recommends prefilling as much information as possible to streamline the checkout process. To prefill the customer’s name, email address, and phone number, supply `defaultBillingDetails` with your customer information after initializing `PaymentSheet.Configuration`. ```swift var configuration = PaymentSheet.Configuration() configuration.defaultBillingDetails.name = "Jenny Rosen" configuration.defaultBillingDetails.email = "jenny.rosen@example.com" configuration.defaultBillingDetails.phone = "888-888-8888" ``` ### Handle user logout `PaymentSheet` stores some information locally to remember whether a user has used Link within an app. To clear the internal state of `PaymentSheet`, call the `PaymentSheet.resetCustomer()` method when your user logs out. ```swift import UIKit import StripePaymentSheet class MyViewController: UIViewController { @objc func didTapLogoutButton() { PaymentSheet.resetCustomer() // Other logout logic required by your app } } ``` ## 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: Enable ACH payments To enable ACH debit payments include `StripeFinancialConnections` as a dependency for your app. 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 **StripeFinancialConnections** 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 'StripeFinancialConnections' ``` 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 StripeFinancialConnections ``` #### 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/StripeFinancialConnections/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 **StripeFinancialConnections.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/StripeFinancialConnections/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. ## 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. ## Optional: Enable CVC recollection on confirmation The following instructions for re-collecting the CVC of a saved card during PaymentIntent confirmation assume that your integration includes the following: - Creation of PaymentIntents before collecting payment details ### Update parameters of the intent creation To re-collect the CVC when confirming payment, include `require_cvc_recollection` during the creation of the PaymentIntent. #### 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 Ephemeral Key for the Customer curl https://api.stripe.com/v1/ephemeral_keys \ -u <>: \ -H "Stripe-Version: 2026-05-27.dahlia" \ -H "Stripe-Account: 2026-05-27.dahlia" \ -X "POST" \ -d "customer"="{{CUSTOMER_ID}}" \ # 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 "payment_method_options[card][require_cvc_recollection]"=true \ -d "automatic_payment_methods[enabled]"=true \ ```
