Accept a payment with Revolut Pay

Create a Stripe account to get started.

Server-side

This integration requires endpoints on your server that communicate with the Stripe API. Use the 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, 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.

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 { 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>
  );
}

Server-side

A PaymentIntent is an object that represents your intent to collect payment from a customer and tracks the lifecycle of the payment process through each stage.

To create and confirm a PaymentIntent on your server:

• Specify the amount to collect and the currency.
• Add revolut_pay to the list of payment method types for your PaymentIntent. Make sure Revolut Pay is enabled in the Dashboard.

curl https://api.stripe.com/v1/payment_intents \
  -u "
sk_test_BQokikJOvBiI2HlWgH4olfQ2
:" \
  -d amount=6000 \
  -d currency=gbp \
  -d "payment_method_types[]"=revolut_pay \
  --data-urlencode return_url="payments-example://stripe-redirect"

The returned PaymentIntent includes a client secret, that you’ll use to confirm the PaymentIntent. Send the client secret back to the client so you can use it in the next step.

Client-side

On the client, request a PaymentIntent from your server and store its client secret:

function PaymentScreen() {
  const fetchPaymentIntentClientSecret = async () => {
    const response = await fetch(`${API_URL}/create-payment-intent`, {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({
        currency: 'gbp',
      }),
    });
    const {clientSecret} = await response.json();

    return clientSecret;
  };

  const handlePayPress = async () => {
    // See below
  };

  return (
    <View>
      <Button onPress={handlePayPress} title="Pay" />
    </View>
  );
}

The client secret is different from your API keys that authenticate Stripe API requests. Handle it carefully because it can complete the charge. Don’t log it, embed it in URLs, or expose it to anyone but the customer.

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 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 { 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>
  );
}

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

When a customer taps to pay with Revolut Pay, complete the payment by calling confirmPayment. This presents a webview where the customer can complete the payment with Revolut Pay. Upon completion, the promise resolves with an object containing either a paymentIntent field, or an error field if an error occurred with the payment.

import {useConfirmPayment} from '@stripe/stripe-react-native';

function PaymentScreen() {
  const {confirmPayment, loading} = useConfirmPayment();

  const fetchPaymentIntentClientSecret = async () => {
    // See above
  };

  const handlePayPress = async () => {
    // Fetch the client secret from the backend.
    const clientSecret = await fetchPaymentIntentClientSecret();

    const {error, paymentIntent} = await confirmPayment(clientSecret, {
      paymentMethodType: 'RevolutPay',
    });

    if (error) {
      console.log('Payment confirmation error: ', error);
    } else if (paymentIntent) {
      console.log('Successfully confirmed payment: ', paymentIntent);
    }
  };

  return (
    <View>
      <Button onPress={handlePayPress} title="Pay" disabled={loading} />
    </View>
  );
}

Test your Revolut Pay integration with your test API keys by viewing the redirect page. You can test the successful payment case by authenticating the payment on the redirect page. The PaymentIntent transitions from requires_action to succeeded.

To test the case where the user fails to authenticate, use your test API keys and view the redirect page. On the redirect page, click Fail test payment. The PaymentIntent transitions from requires_action to requires_payment_method.

For manual capture PaymentIntents in testmode, the uncaptured PaymentIntent auto-expires 10 minutes after successful authorization.

As a best practice, test it in live mode with a real Revolut Pay account before releasing it to your customers.
