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Updating to a newer version of the SDK?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.

Pre-built payments UI (beta): Learn how to integrate Payment Sheet, our new pre-built payments UI for mobile apps. Our pre-built UI lets you accept cards, Apple Pay, and Google Pay out of the box, and includes support for saving & reusing cards. We'll be adding support for many more payment method during the beta.

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
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.

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

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

Set appropriate style in your styles.xml file

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

iOS

Compatible with apps targeting iOS 11 or above.

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"
    >
      <PaymentScreen />
    </StripeProvider>
  );
}

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

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

  return (
    <CardField
      postalCodeEnabled={true}
      placeholder={{
        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"
    >
      // Your app code here
    </StripeProvider>
  );
}

or

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

function App() {
  // ...

  useEffect(() => {
    initStripe({
      publishableKey: publishableKey
      merchantIdentifier: 'merchant.identifier',
    });
  }, []);
}

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

Run the example app

Install the dependencies
- yarn bootstrap
Set up env vars
- cp example/.env.example example/.env and set the variable values in your newly created .env file.
Start the example
- Terminal 1: yarn example start:server
- Terminal 2: yarn example start
- Terminal 3: depending on what platform you want to build for run either
  - yarn example ios
  - or
  - yarn example android

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 presentApplePayMock = jest.fn();

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

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) 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.
