# Accept a payment

Securely accept payments online.

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();`.

Coding agents should install the Stripe CLI (`npm i -g @stripe/cli`) and run the command `stripe sandbox create --help` to provision an anonymous Stripe sandbox with working API keys. No account registration required.

Build a payment form or use a prebuilt checkout page to start accepting online payments.

# In-app integration for React Native

![](https://b.stripecdn.com/docs-statics-srv/assets/ios-overview.9e0d68d009dc005f73a6f5df69e00458.png)

This integration combines all of the steps required to pay, including collecting payment details and confirming the payment, into a single sheet that displays on top of your app.

> #### 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 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 (
    <StripeProvider
      publishableKey={publishableKey}
      merchantIdentifier="merchant.identifier" // required for Apple Pay
      urlScheme="your-url-scheme" // required for 3D Secure and bank redirects
    >
      {/* Your app code here */}
    </StripeProvider>
  );
}
```

> 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

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.

2. (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.

3. (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.
2. Creates a [CustomerSession](https://docs.stripe.com/api/customer_sessions.md) for the `Account` or `Customer`.
3. 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).
4. 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.

```

> 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.

#### Accounts v2

```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_account } = await response.json();

    return {
      paymentIntent,
      ephemeralKey,
      customer_account,
    };
  };

  const initializePaymentSheet = async () => {
    const {
      paymentIntent,
      ephemeralKey,
      customer_account,
    } = await fetchPaymentSheetParams();

    const { error } = await initPaymentSheet({
      merchantDisplayName: "Example, Inc.",
      customerAccountId: customer_account,
      customerEphemeralKeySecret: ephemeralKey,
      paymentIntentClientSecret: paymentIntent,
      // Set `allowsDelayedPaymentMethods` to true if your business accepts 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 (
    <Screen>
      <Button
        variant="primary"
        disabled={!loading}
        title="Checkout"
        onPress={openPaymentSheet}
      />
    </Screen>
  );
}
```

#### Customers v1

```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 (
    <Screen>
      <Button
        variant="primary"
        disabled={!loading}
        title="Checkout"
        onPress={openPaymentSheet}
      />
    </Screen>
  );
}
```

When your customer taps the **Checkout** button, call `presentPaymentSheet()` to open the sheet. After the customer completes the payment, the sheet is dismissed and the promise resolves with an optional `StripeError<PaymentSheetError>`.

```javascript
export default function CheckoutScreen() {
  // continued from above

  const openPaymentSheet = async () => {
    const { error } = await presentPaymentSheet();

    if (error) {
      Alert.alert(`Error code: ${error.code}`, error.message);
    } else {
      Alert.alert('Success', 'Your order is confirmed!');
    }
  };

  return (
    <Screen>
      <Button
        variant="primary"
        disabled={!loading}
        title="Checkout"
        onPress={openPaymentSheet}
      />
    </Screen>
  );
}
```

If there is no error, inform the customer they’re done (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 (iOS only) [Client-side]

When a customer exits your app (for example to authenticate in Safari or their banking app), provide a way for them to automatically return to your app. Many payment method types *require* a return URL. If you don’t provide one, we can’t present payment methods that require a return URL to your users, even if you’ve enabled them.

To provide a return URL:

1. [Register](https://developer.apple.com/documentation/xcode/defining-a-custom-url-scheme-for-your-app#Register-your-URL-scheme) a custom URL. Universal links aren’t supported.
2. [Configure](https://reactnative.dev/docs/linking) your custom URL.
3. Set up your root component to forward the URL to the Stripe SDK as shown below.

> If you’re using Expo, [set your scheme](https://docs.expo.io/guides/linking/#in-a-standalone-app) in the `app.json` file.

```jsx
import { useEffect, useCallback } from 'react';
import { Linking, View } from 'react-native';
import { useStripe } from '@stripe/stripe-react-native';

export default function MyApp() {
  const { handleURLCallback } = useStripe();

  const handleDeepLink = useCallback(
    async (url: string | null) => {
      if (url) {
        const stripeHandled = await handleURLCallback(url);
        if (stripeHandled) {
          // This was a Stripe URL - you can return or add extra handling here as you see fit
        } else {
          // This was NOT a Stripe URL – handle as you normally would
        }
      }
    },
    [handleURLCallback]
  );

  useEffect(() => {
    const getUrlAsync = async () => {
      const initialUrl = await Linking.getInitialURL();
      handleDeepLink(initialUrl);
    };

    getUrlAsync();

    const deepLinkListener = Linking.addEventListener(
      'url',
      (event: { url: string }) => {
        handleDeepLink(event.url);
      }
    );

    return () => deepLinkListener.remove();
  }, [handleDeepLink]);

  return (
    <View>
      <AwesomeAppComponent />
    </View>
  );
}
```

Additionally, set the `returnURL` when you call the `initPaymentSheet` method:

```js
await initPaymentSheet({
  ...
  returnURL: 'your-app://stripe-redirect',
  ...
});
```

For more information on native URL schemes, refer to the [Android](https://developer.android.com/training/app-links/deep-linking) and [iOS](https://developer.apple.com/documentation/xcode/allowing_apps_and_websites_to_link_to_your_content/defining_a_custom_url_scheme_for_your_app) docs.

## Handle post-payment events

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                                                                                                                                                                                           |

See [Testing](https://docs.stripe.com/testing.md) for additional information to test your integration.

## Enable card scanning [Client-side]

> Enabling card scanning is required for Apple’s iOS app review process. Card scanning is not required for Android’s app review process, but we recommend enabling it.

### iOS

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) Android

To enable card scanning support, [request production access](https://developers.google.com/pay/api/android/guides/test-and-deploy/request-prod-access) to the Google Pay API from the [Google Pay and Wallet Console](https://pay.google.com/business/console?utm_source=devsite&utm_medium=devsite&utm_campaign=devsite).

- If you’ve enabled Google Pay, the card scanning feature is automatically available in our UI on eligible devices. To learn more about eligible devices, see the [Google Pay API constraints](https://developers.google.com/pay/payment-card-recognition/debit-credit-card-recognition)
- **Important:** The card scanning feature only appears in builds signed with the same signing key registered in the [Google Pay & Wallet Console](https://pay.google.com/business/console). Test or debug builds using different signing keys (for example, builds distributed through Firebase App Tester) won’t show the **Scan card** option. To test card scanning in pre-release builds, you must either:
  - Sign your test builds with your production signing key
  - Add your test signing key fingerprint to the Google Pay and Wallet Console

If your app doesn’t support Google Pay, you can use the Stripe card scanner.

> The Stripe card scanner is in public preview.

To enable card scanning support, 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:23.12.0'
```

## 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 to `initPaymentSheet`.

```javascript
await initPaymentSheet({
  ...
  defaultBillingDetails: {
    name: 'Jenny Rosen',
    email: 'jenny.rosen@example.com',
    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 `resetPaymentSheetCustomer()` method when your user logs out.

```javascript
export default function CheckoutScreen() {
  // continued from above
  const { initPaymentSheet, presentPaymentSheet, resetPaymentSheetCustomer } = useStripe();

  const logout = async () => {
    await resetPaymentSheetCustomer();
  };

  return (
    <Screen>
      <Button
        title="Checkout"
        onPress={openPaymentSheet}
      />
      <Button
        title="Checkout"
        onPress={logout}
      />
    </Screen>
  );
}
```

## Optional: Enable Apple Pay

### 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

Pass your merchant ID when you create `StripeProvider`:

```javascript
import { StripeProvider } from '@stripe/stripe-react-native';

function App() {
  return (
    <StripeProvider
      publishableKey="<<YOUR_PUBLISHABLE_KEY>>"
      merchantIdentifier="MERCHANT_ID"
    >
      {/* Your app code here */}
    </StripeProvider>
  );
}
```

When you call `initPaymentSheet`, pass in your [ApplePayParams](https://stripe.dev/stripe-react-native/api-reference/modules/PaymentSheet.html#ApplePayParams):

```javascript
await initPaymentSheet({
  // ...
  applePay: {
    merchantCountryCode: 'US',
  },
});
```

#### Recurring payments

When you call `initPaymentSheet`, pass in an [ApplePayParams](https://stripe.dev/stripe-react-native/api-reference/modules/PaymentSheet.html#ApplePayParams) with `merchantCountryCode` set to the country code of your business.

In accordance with [Apple’s guidelines](https://developer.apple.com/design/human-interface-guidelines/apple-pay#Supporting-subscriptions) for recurring payments, you must also set a `cardItems` that includes a [RecurringCartSummaryItem](https://stripe.dev/stripe-react-native/api-reference/modules/ApplePay.html#RecurringCartSummaryItem) with the amount you intend to charge (for example, “59.95 USD a month”).

You can also adopt [merchant tokens](https://developer.apple.com/apple-pay/merchant-tokens/) by setting the `request` with its `type` set to `PaymentRequestType.Recurring`

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 (React Native)

```javascript
const initializePaymentSheet = async () => {
  const recurringSummaryItem = {
    label: 'My Subscription',
    amount: '59.99',
    paymentType: 'Recurring',
    intervalCount: 1,
    intervalUnit: 'month',
    // Payment starts today
    startDate: new Date().getTime() / 1000,

    // Payment ends in one year
    endDate: new Date().getTime() / 1000 + 60 * 60 * 24 * 365,
  };

  const {error} = await initPaymentSheet({
    // ...
    applePay: {
      merchantCountryCode: 'US',
      cartItems: [recurringSummaryItem],
      request: {
        type: PaymentRequestType.Recurring,
        description: 'Recurring',
        managementUrl: 'https://my-backend.example.com/customer-portal',
        billing: recurringSummaryItem,
        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.'",
      },
    },
  });
};
```

### 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 a `setOrderTracking` callback function. Stripe calls your implementation after the payment is complete, but before iOS dismisses the Apple Pay sheet.

In your implementation of `setOrderTracking` callback function, fetch the order details from your server for the completed order, and pass the details to the provided `completion` function.

To learn more about order tracking, see [Apple’s Wallet Orders documentation](https://developer.apple.com/documentation/walletorders).

#### iOS (React Native)

```javascript
await initPaymentSheet({
  // ...
  applePay: {
    // ...
    setOrderTracking: async complete => {
      const apiEndpoint =
        Platform.OS === 'ios'
          ? 'http://localhost:4242'
          : 'http://10.0.2.2:4567';
      const response = await fetch(
        `${apiEndpoint}/retrieve-order?orderId=${orderId}`,
        {
          method: 'GET',
          headers: {
            'Content-Type': 'application/json',
          },
        },
      );
      if (response.status === 200) {
        const orderDetails = await response.json();
        // orderDetails should include orderIdentifier, orderTypeIdentifier,
        // authenticationToken and webServiceUrl
        complete(orderDetails);
      }
    },
  },
});
```

## Optional: Enable Google Pay

### Set up your integration

To use Google Pay, first enable the Google Pay API by adding the following to the `<application>` tag of your **AndroidManifest.xml**:

```xml
<application>
  ...
  <meta-data
    android:name="com.google.android.gms.wallet.api.enabled"
    android:value="true" />
</application>
```

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

When you initialize `PaymentSheet`, set `merchantCountryCode` to the country code of your business and set `googlePay` to true.

You can also use the test environment by passing the `testEnv` parameter. You can only test Google Pay on a physical Android device. Follow the [React Native docs](https://reactnative.dev/docs/running-on-device) to test your application on a physical device.

```javascript
const { error, paymentOption } = await initPaymentSheet({
  // ...
  googlePay: {
    merchantCountryCode: 'US',
    testEnv: true, // use test environment
  },
});
```

## Optional: Customize the sheet [Client-side]

All customization is configured using `initPaymentSheet`.

### 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=react-native).

### Merchant display name

Specify a customer-facing business name by setting `merchantDisplayName`. By default, this is your app’s name.

```javascript
await initPaymentSheet({
  // ...
  merchantDisplayName: 'Example Inc.',
});
```

### 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 the `style` property to `alwaysLight` or `alwaysDark` mode on iOS.

```javascript
await initPaymentSheet({
  // ...
  style: 'alwaysDark',
});
```

On Android, set light or dark mode on your app:

```
// force dark
AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES)
// force light
AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_NO)
```

## Optional: Complete payment in your UI

You can present 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 payment details are collected.
![](https://b.stripecdn.com/docs-statics-srv/assets/react-native-multi-step.84d8a0a44b1baa596bda491322b6d9fd.png)

> A sample integration is [available on our GitHub](https://github.com/stripe/stripe-react-native/blob/master/example/src/screens/PaymentsUICustomScreen.tsx).

1. First, call `initPaymentSheet` and pass `customFlow: true`. `initPaymentSheet` resolves with an initial payment option containing an image and label representing the customer’s payment method. Update your UI with these details.

```javascript
const {
  initPaymentSheet,
  presentPaymentSheet,
  confirmPaymentSheetPayment,
} = useStripe()

const { error, paymentOption } = await initPaymentSheet({
  customerId: customer,
  customerEphemeralKeySecret: ephemeralKey,
  paymentIntentClientSecret: paymentIntent,
  customFlow: true,
  merchantDisplayName: 'Example Inc.',
});
// Update your UI with paymentOption
```

1. Use `presentPaymentSheet` to collect payment details. When the customer finishes, the sheet dismisses itself and resolves the promise. Update your UI with the selected payment method details.

```javascript
const { error, paymentOption } = await presentPaymentSheet();
```

1. Use `confirmPaymentSheetPayment` to confirm the payment. This resolves with the result of the payment.

```javascript
const { error } = await confirmPaymentSheetPayment();

if (error) {
  Alert.alert(`Error code: ${error.code}`, error.message);
} else {
  Alert.alert(
    'Success',
    'Your order is confirmed!'
  );
}
```

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.
