Accept in-app payments

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:

# Available as a gem
sudo gem install stripe

# If you use bundler, you can add this line to your Gemfile
gem 'stripe'

Client-side

The React Native SDK is open source and fully documented. Internally, it uses the native iOS and 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 add @stripe/stripe-react-native

Next, install some other necessary dependencies:

• For iOS, navigate 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.

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 in publishableKey is required. The following example shows how to initialize Stripe using the StripeProvider component.

import React, { 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>
  );
}

View your payment methods settings and enable the payment methods you want to support. You need at least one payment method enabled to create a SetupIntent.

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 for product and payment method support, and our pricing page for fees.

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 afterward. Many payment method types require a return URL, so if you fail to provide it, we can’t present those payment methods to your user, even if you’ve enabled them.

To provide a return URL:

1. Register a custom URL. Universal links aren’t supported.
2. Configure your custom URL.
3. Set up your root component to forward the URL to the Stripe SDK as shown below.

import React, { useEffect, useCallback } from 'react';
import { Linking } 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:

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

For more information on native URL schemes, refer to the Android and iOS docs.

To set up a payment method for future payments, you must attach it to a Customer. Create a Customer object when your customer creates an account with your business. Customer objects allow for reusing payment methods and tracking across multiple payments.

curl -X POST https://api.stripe.com/v1/customers \

The integration can use the default payment flow or a custom flow.

Default	Custom flow
Displays a sheet to collect payment details and complete the setup. The button in the sheet says Set up and sets up the payment method.	Displays a sheet to collect payment details only. The button in the sheet says Continue and returns the customer to your app, where your own button completes the setup.

import { useStripe, useEffect } from '@stripe/stripe-react-native';
import {View, Button} from 'react-native';

export default function CheckoutScreen() {
  const { initPaymentSheet, presentPaymentSheet } = useStripe();

  const initializePaymentSheet = async () => {
    const { error } = await initPaymentSheet({
      merchantDisplayName: "Example, Inc.",
      intentConfiguration: {
        mode: {
          currencyCode: 'USD',
        },
        confirmHandler: confirmHandler
      }
    });
    if (error) {
      // handle error
    }
  };

  useEffect(() => {
    initializePaymentSheet();
  }, []);

  const confirmHandler = async (
    paymentMethod: PaymentMethod.Result,
    shouldSavePaymentMethod: boolean,
    intentCreationCallback: (params: IntentCreationCallbackParams) => void
  ) => {
    // explained later
  }

  const didTapCheckoutButton = async () => {
    // implement later
  }
  return (
    <View>
      <Button
        title="Checkout"
        onPress={didTapCheckoutButton}
      />
    </View>
  );
}

export default function CheckoutScreen() {
  // ...
  const didTapCheckoutButton = async () => {
    const { error } = await presentPaymentSheet();

    if (error) {
      if (error.code === PaymentSheetError.Canceled) {
        // Customer canceled - you should probably do nothing.
      } else {
        // PaymentSheet encountered an unrecoverable error. You can display the error to the user, log it, etc.
      }
    } else {
      // Setup completed - show a confirmation screen.
    }
  }
  // ...
}

export default function CheckoutScreen() {
  // ...

  const confirmHandler = async (
    paymentMethod: PaymentMethod.Result,
    shouldSavePaymentMethod: boolean,
    intentCreationCallback: (params: IntentCreationCallbackParams) => void
  ) => {
    // Make a request to your own server.
    const response = await fetch(`${API_URL}/create-intent`, {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
    }});
    // Call the `intentCreationCallback` with your server response's client secret or error
    const { client_secret, error } = await response.json();
    if (client_secret) {
      intentCreationCallback({clientSecret: client_secret});
    } else {
      intentCreationCallback({error});
    }
  }
  // ...
}

On your server, create a SetupIntent. You can manage payment methods from the Dashboard. Stripe evaluates payment method restrictions and other parameters to determine the list of supported payment methods.

If the call succeeds, return the SetupIntent client secret. If the call fails, handle the error and return an error message with a brief explanation for your customer.

require 'stripe'
Stripe.api_key = 
'sk_test_BQokikJOvBiI2HlWgH4olfQ2'

post '/create-intent' do
  data = JSON.parse request.body.read
  params = {
    customer: ..., # The Customer ID you previously created
    # In the latest version of the API, specifying the `automatic_payment_methods` parameter is optional because Stripe enables its functionality by default.
    automatic_payment_methods: {enabled: true},
  }
  begin
    intent = Stripe::SetupIntent.create(params)
    {client_secret: intent.client_secret}.to_json
  rescue Stripe::StripeError => e
    {error: e.error.message}.to_json
  end
end

When you’re ready to charge your customer off-session, use the Customer and PaymentMethod IDs to create a PaymentIntent. To find a payment method to charge, list the payment methods associated with your customer. This example lists cards but you can list any supported type.

curl -G https://api.stripe.com/v1/payment_methods \
  -u "
sk_test_BQokikJOvBiI2HlWgH4olfQ2
:" \
  -d customer=
{{CUSTOMER_ID}} \
  -d type=card

When you have the Customer and PaymentMethod IDs, create a PaymentIntent with the amount and currency of the payment. Set a few other parameters to make the off-session payment:

• Set off_session to true to indicate that the customer isn’t in your checkout flow during a payment attempt and can’t fulfill an authentication request made by a partner, such as a card issuer, bank, or other payment institution. If, during your checkout flow, a partner requests authentication, Stripe requests exemptions using customer information from a previous on-session transaction. If the conditions for exemption aren’t met, the PaymentIntent might throw an error.
• Set the value of the PaymentIntent’s confirm property to true, which causes confirmation to occur immediately when the PaymentIntent is created.
• Set payment_method to the ID of the PaymentMethod and customer to the ID of the Customer.

curl https://api.stripe.com/v1/payment_intents \
  -u 
sk_test_BQokikJOvBiI2HlWgH4olfQ2
: \
  -d amount=1099 \
  -d currency=usd \
  # In the latest version of the API, specifying the `automatic_payment_methods` parameter is optional because Stripe enables its functionality by default.
  -d "automatic_payment_methods[enabled]"=true \
  -d customer="{{CUSTOMER_ID}}" \
  -d payment_method="{{PAYMENT_METHOD_ID}}" \
  -d return_url="https://example.com/order/123/complete" \
  -d off_session=true \
  -d confirm=true
