React Native library for Stripe.

Stripe React Native SDK

The Stripe React Native SDK allows you to build delightful payment experiences in your native Android and iOS apps using React Native. We provide powerful and customizable UI screens and elements that can be used out-of-the-box to collect your users' payment details.

Getting started

Get started with our 📚 integration guides and example project, or 📘 browse the SDK reference.

Updating to a newer version of the SDK? See our changelog.

Features

Simplified Security: We make it simple for you to collect sensitive data such as credit card numbers and remain PCI compliant. This means the sensitive data is sent directly to Stripe instead of passing through your server. For more information, see our Integration Security Guide.

Apple Pay: We provide a seamless integration with Apple Pay.

Payment methods: Accepting more payment methods helps your business expand its global reach and improve checkout conversion.

SCA-Ready: The SDK automatically performs native 3D Secure authentication if needed to comply with Strong Customer Authentication regulation in Europe.

Native UI: We provide native screens and elements to securely collect payment details on Android and iOS.

PaymentSheet: Learn how to integrate PaymentSheet, our new pre-built payments UI for mobile apps. PaymentSheet lets you accept cards, Apple Pay, Google Pay, and much more out of the box and also supports saving & reusing payment methods. PaymentSheet currently accepts the following payment methods: Card, Apple Pay, Google Pay, SEPA Debit, Bancontact, iDEAL, EPS, P24, Afterpay/Clearpay, Klarna, Giropay, Sofort, and ACH.

Recommended usage

If you're selling digital products or services within your app, (e.g. subscriptions, in-game currencies, game levels, access to premium content, or unlocking a full version), you must use the app store's in-app purchase APIs. See Apple's and Google's guidelines for more information. For all other scenarios you can use this SDK to process payments via Stripe.

Installation

yarn add @stripe/stripe-react-native
or
npm install @stripe/stripe-react-native

Expo

Find Expo's full documentation here.

Each Expo SDK version requires a specific stripe-react-native version. See the CHANGELOG for a mapping of versions. To install the correct version for your Expo SDK version run:

expo install @stripe/stripe-react-native

Next, add:

{
  "expo": {
    ...
    "plugins": [
      [
        "@stripe/stripe-react-native",
        {
          "merchantIdentifier": string | string [],
          "enableGooglePay": boolean
        }
      ]
    ],
  }
}

to your app.json file, where merchantIdentifier is the Apple merchant ID obtained here. Otherwise, Apple Pay will not work as expected. If you have multiple merchantIdentifiers, you can set them in an array.

Requirements

Android

• Android 5.0 (API level 21) and above
  • Your compileSdkVersion must be 33. See this issue for potential workarounds.
• Android gradle plugin 4.x and above

Components

In order to use CardForm component, you need to install and configure Material Components theme in your app.

1. Add below dependency to your app/build.gradle file with specified version

implementation 'com.google.android.material:material:<version>'

2. Set appropriate style in your styles.xml file

<style name="Theme.MyApp" parent="Theme.MaterialComponents.DayNight">
    <!-- ... -->
</style>

iOS

The Stripe React Native SDK requires Xcode 14.1 or later and is compatible with apps targeting iOS 13 or above. For iOS 12 support, please use @stripe/[email protected].

The SDK uses TypeScript features available in Babel version 7.9.0 and above. Alternatively use the plugin-transform-typescript plugin in your project.

You'll need to run pod install in your ios directory to install the native dependencies.

Usage example

// App.ts
import { StripeProvider } from '@stripe/stripe-react-native';

function App() {
  return (
    <StripeProvider
      publishableKey={publishableKey}
      merchantIdentifier="merchant.identifier" // required for Apple Pay
      urlScheme="your-url-scheme" // required for 3D Secure and bank redirects
    >
      <PaymentScreen />
    </StripeProvider>
  );
}

// PaymentScreen.ts
import { CardField, useStripe } from '@stripe/stripe-react-native';

export default function PaymentScreen() {
  const { confirmPayment } = useStripe();

  return (
    <CardField
      postalCodeEnabled={true}
      placeholders={{
        number: '4242 4242 4242 4242',
      }}
      cardStyle={{
        backgroundColor: '#FFFFFF',
        textColor: '#000000',
      }}
      style={{
        width: '100%',
        height: 50,
        marginVertical: 30,
      }}
      onCardChange={(cardDetails) => {
        console.log('cardDetails', cardDetails);
      }}
      onFocus={(focusedField) => {
        console.log('focusField', focusedField);
      }}
    />
  );
}

Stripe initialization

To initialize Stripe in your React Native app, use the StripeProvider component in the root component of your application, or use the initStripe method.

StripeProvider can accept urlScheme, publishableKey, stripeAccountId, threeDSecureParams and merchantIdentifier as props. Only publishableKey is required.

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>
  );
}

or

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

function App() {
  // ...

  useEffect(() => {
    initStripe({
      publishableKey: publishableKey,
      merchantIdentifier: 'merchant.identifier',
      urlScheme: "your-url-scheme",
    });
  }, []);
}

You can find more details about the StripeProvider component in the API reference.

Additional steps for webhook forwarding

Certain payment methods require a webhook listener to notify you of changes in the status. When developing locally, you can use the Stripe CLI to forward webhook events to your local dev server.

• Install the stripe-cli
• Run stripe listen --forward-to localhost:4242/webhook
• The CLI will print a webhook secret (such as, whsec_***) to the console. Set STRIPE_WEBHOOK_SECRET to this value in your example/.env file.

Testing

This library includes a built in mock file for Jest. In order to use it, add the following code to the Jest setup file:

import mock from '@stripe/stripe-react-native/jest/mock.js';

jest.mock('@stripe/stripe-react-native', () => mock);

To have a more control over the mocks, you can extend and override particular methods e.g.:

const presentNativePayMock = jest.fn();

jest.mock('@stripe/stripe-react-native', () => ({
  ...mock,
  presentNativePay: presentNativePayMock,
}));

Troubleshooting

Undefined symbols for architecture x86_64 on iOS

While building your iOS project, you may see a Undefined symbols for architecture x86_64 error. This is caused by react-native init template configuration that is not fully compatible with Swift 5.1.

Undefined symbols for architecture x86_64:
  "(extension in Foundation):__C.NSScanner.scanUpToString(Swift.String) -> Swift.String?", referenced from:
      static Stripe.STPPhoneNumberValidator.formattedRedactedPhoneNumber(for: Swift.String, forCountryCode: Swift.String?) -> Swift.String in libStripe.a(STPPhoneNumberValidator.o)
  "__swift_FORCE_LOAD_$_swiftUniformTypeIdentifiers", referenced from:
      __swift_FORCE_LOAD_$_swiftUniformTypeIdentifiers_$_Stripe in libStripe.a(PKPaymentAuthorizationViewController+Stripe_Blocks.o)

Follow these steps to resolve this:

• Open your project via Xcode, go to project -> build settings, find library search paths and remove all swift related entries such as: $(TOOLCHAIN_DIR)/usr/lib/swift/$(PLATFORM_NAME) and $(TOOLCHAIN_DIR)/usr/lib/swift-5.0/$(PLATFORM_NAME).
• Create a new Swift file to the project (File > New > File > Swift), give it any name (e.g. Fix.swift), check the appropriate Targets and create a bridging header when prompted by Xcode.

TypeError: null is not an object (evaluating '_NativeStripeSdk.default.initialise') on Android

You might see error this whilst initializing the StripeProvider component with Expo. This is caused by using an older version of Expo before stripe-react-native was officially supported. Updating Expo Go from the stores (or locally on simulators installed with expo install:client:[ios|android]) should fix the problem.

If you're still having troubles, please open an issue or jump in our developer chat.

Apple Pay Is Not Available in "My App Name"

This can occur if you attempt to process an Apple Pay payment on a physical device (even in test mode) without having created and uploaded your Apple Pay Certificate to the Stripe Dashboard. Learn how to do that here.
