# Build a mobile integration

# Build a checkout screen with Payment Intents API 

Learn how to embed a custom Stripe payment form in your iOS or Android application. The client- and server-side code builds a checkout screen with Stripe’s [Mobile Elements](https://docs.stripe.com/payments/mobile.md) to let you accept payments. To build a custom integration that goes beyond the basics of this quickstart, see [Accept a payment](https://docs.stripe.com/payments/accept-a-payment.md?payment-ui=mobile).

### Create a PaymentIntent

Add an endpoint on your server that creates a [PaymentIntent](https://docs.stripe.com/api/payment_intents.md). A PaymentIntent tracks the customer’s payment lifecycle, keeping track of any failed payment attempts and ensuring the customer is only charged once. Return 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)) in the response to finish the payment on the client.

### Configure payment methods

 Stripe enables cards and other common payment methods by default with [dynamic payment methods](https://docs.stripe.com/payments/payment-methods/dynamic-payment-methods.md). You can update and configure payment methods from the [Dashboard](https://dashboard.stripe.com/settings/payment_methods) with no code required. Stripe filters payment methods based on eligibility and payment method preferences, then orders and displays them by probability based on factors including amount, currency, and customer location.

### Install the SDK

The Stripe iOS SDK is [open source](https://github.com/stripe/stripe-ios), [fully documented](https://stripe.dev/stripe-ios/), and compatible with apps supporting iOS 13 or above. Import the Stripe SDK into your checkout screen’s View Controller.

#### Swift Package Manager

In Xcode, select **File** > **Add Package Dependencies……** and enter `https://github.com/stripe/stripe-ios-spm` as the repository URL. Select the latest version number from our [releases page](https://github.com/stripe/stripe-ios/releases), and add the `StripePaymentSheet` module to your app’s target.

#### CocoaPods

Add this line to your Podfile, and use the .xcworkspace file to open your project in Xcode, instead of the .xcodeproj file, from here on out.

```bash
pod 'StripePaymentSheet'
```

#### Carthage

Add this line to your Cartfile.

```bash
github "stripe/stripe-ios"
```

#### Manual Framework

To include Stripe in your project, download and unzip Stripe.xcframework.zip from a [release on GitHub](https://github.com/stripe/stripe-ios/releases). Drag the required xcframework files to the “Embedded Binaries” settings in your Xcode project. Make sure to select “Copy items if needed”.

### Setup the SDK

Configure the Stripe SDK with your Stripe [publishable API key](https://docs.stripe.com/keys.md#obtain-api-keys). Hardcoding the publishable API key in the SDK is for demonstration only. In a production app, you must retrieve the API key from your server.

### Fetch a PaymentIntent

Make a request to your server for a PaymentIntent as soon as the view loads. Store a reference to 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)) returned by the server; the Payment Sheet uses this secret to complete the payment later.

### Configure and present the Payment Sheet

Create a `PaymentSheet` instance using the client secret retrieved earlier, and present it from your view controller.

Use the `PaymentSheet.Configuration` struct for [customizing](https://stripe.dev/stripe-ios/stripe-paymentsheet/Classes/PaymentSheet/Configuration.html) the Payment Sheet.

### Handle the payment result

Use the completion block for handling the payment result.

If payment fails with an [error](https://docs.stripe.com/error-codes.md), display the appropriate message to your customer so they can take action and try again. If no error has occurred, tell your customer that the payment was successful.

### Make a test payment

#### iOS

To verify that your integration works, make a test payment using [test payment details](https://docs.stripe.com/payments/accept-a-payment.md?payment-ui=mobile&platform=ios#ios-test-the-integration).

#### Android

To verify that your integration works, make a test payment using [test payment details](https://docs.stripe.com/payments/accept-a-payment.md?payment-ui=mobile&platform=android#android-test-the-integration).

### See your payment in the Dashboard

Navigate to the [Stripe Dashboard](https://dashboard.stripe.com/test/payments) to see your test payment.

## Accept payments and enhance your integration

You’re ready to accept payments with Stripe. Continue with the steps below to add more features.

### Automate tax collection

Calculate and collect the right amount of tax on your Stripe transactions. Before using Stripe Tax, you need to activate it in the [Dashboard](https://dashboard.stripe.com/tax). Learn more about [Stripe Tax](https://docs.stripe.com/tax.md) and [how to add it to your Payments integration](https://docs.stripe.com/tax/standalone-tax-api.md).

### Use the Stripe Tax API to calculate tax

Use the [Stripe Tax API](https://docs.stripe.com/api/tax/calculations/create.md) to calculate tax on the transaction. Provide the `currency`, `customer_details`, and the `line_items` of the order in the request body.

Use the `tax_amount_exclusive` attribute of the resulting Tax Calculation to add the exclusive taxes to the order’s total.

### Record a Tax Transaction upon successful Payment

Link the tax calculation to the PaymentIntent using `hooks[inputs][tax][calculation]`.

This records the collected taxes in your Stripe account that you can later export for accounting purposes, and triggers other [Stripe actions](https://docs.stripe.com/tax/payment-intent/simplified.md#automatic-actions).

### Allow delayed payment methods

Some payment methods can’t guarantee that you’ll receive funds from your customer at the end of the check out because they take time to settle (for example, most bank debits, such as SEPA or ACH) or require customer action to complete (for example, OXXO, Konbini, Boleto). Use this flag to enable delayed payment methods.

If you enable this feature, make sure your server integration listens to [webhooks](https://docs.stripe.com/payments/payment-methods.md#payment-notification) for notifications on whether payment has succeeded or not.

### Add Apple Pay support

To enable Apple Pay, provide your [Apple Pay Merchant ID](https://support.stripe.com/questions/enable-apple-pay-on-your-stripe-account) and your Stripe account’s [country code](https://dashboard.stripe.com/settings/account).

### Add Google Pay support

To use Google Pay, first enable the Google Pay API in your AndroidManifest.xml.

Enable Google Pay by passing a [PaymentSheet.GooglePayConfiguration](https://stripe.dev/stripe-android/paymentsheet/com.stripe.android.paymentsheet/-payment-sheet/-google-pay-configuration/index.html) object with the 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).

### Customize the primary button color

Consider using a custom color for the primary button that better matches your brand or app’s visual identity.

### Enable card scanning

Card scanning can help increase your conversion rate by removing the friction of manual card entry. To enable card scanning, set `NSCameraUsageDescription` in your application’s `Info.plist`, and provide a reason for accessing the camera (for example, “To scan cards”).

> Card scanning is only supported on devices running iOS 13 or higher.

### Enable card scanning

Card scanning can help increase your conversion rate by removing the friction of manual card entry. To enable card scanning, add `stripecardscan` to the `dependencies` block of your [app/build.gradle](https://developer.android.com/studio/build/dependencies) file:

#### Groovy

```groovy
implementation 'com.stripe:stripecardscan:23.15.0'
```

### Import additional Stripe resources

Import the Stripe PaymentMethod and Customer models. Use these models to store information about your Customer.

### Create a customer

Stripe stores the card on a *Customer* (Customer objects represent customers of your business. They let you reuse payment methods and give you the ability to track multiple payments) object. Create a new Customer before creating a PaymentIntent. You can also store name, email, shipping address, and other details on the Customer.

### Create a customer

Stripe stores the card on an [Account](https://docs.stripe.com/api/v2/core/accounts/object.md) object representing the [customer](https://docs.stripe.com/connect/account-capabilities.md?accounts-namespace=v2#customer). Create a new Account before creating a PaymentIntent. You can also store name, email, shipping address, and other details on the Account.

### Add the customer to the PaymentIntent

Pass the Customer ID to the PaymentIntent and set `setup_future_usage` to `off_session`. `setup_future_usage` tells Stripe how you plan to use the payment method—certain regions, such as Europe and India, have requirements around reusing payment details. [Learn more](https://docs.stripe.com/payments/payment-intents.md#future-usage) about the most effective way to apply `setup_future_usage`. You can also view a [list of supported payment methods](https://docs.stripe.com/payments/payment-methods/payment-method-support.md#additional-api-supportability). After the PaymentIntent succeeds, Stripe automatically [attaches](https://docs.stripe.com/api/payment_methods/attach.md) the payment details (in a *PaymentMethod* (PaymentMethods represent your customer's payment instruments, used with the Payment Intents or Setup Intents APIs) object) to your Customer.

### Add the customer to the PaymentIntent

### Install the SDK

The Stripe Android SDK is [open source](https://github.com/stripe/stripe-android) and [fully documented](https://stripe.dev/stripe-android/) and compatible with devices running Android 5.0 (API level 21) and above.

To install the SDK, add `stripe-android` to the dependencies block of your `build.gradle` file:

#### Groovy

```groovy
implementation 'com.stripe:stripe-android:23.15.0'
```

> For details on the latest SDK release and past versions, see the [Releases page](https://github.com/stripe/stripe-android/releases) on GitHub.

### Setup the SDK

Configure the Stripe SDK with your Stripe [publishable API key](https://docs.stripe.com/keys.md#obtain-api-keys). Hardcoding the publishable API key in the SDK is for demonstration only. In a production app, you must retrieve the API key from your server.

### Fetch a PaymentIntent

Make a request to your server for a PaymentIntent as soon as the view loads. Store a reference to 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)) returned by the server; the Payment Sheet uses this secret to complete the payment later.

### Configure and present the Payment Sheet

Create a `PaymentSheet` instance using the client secret retrieved earlier, and present it from your view controller.

Use the `PaymentSheet.Configuration` struct for [customizing](https://stripe.dev/stripe-ios/stripe-paymentsheet/Classes/PaymentSheet/Configuration.html) the Payment Sheet.

### Handle the payment result

Use the completion block for handling the payment result.

If payment fails with an [error](https://docs.stripe.com/error-codes.md), display the appropriate message to your customer so they can take action and try again. If no error has occurred, tell your customer that the payment was successful.
