@google/react-native-make-payment

react-native-make-payment

Adds native payments using the W3C Payment Request API to your React Native app. Currently supports Google Pay on Android, with support planned for other platforms in the future.

Installation

npm install @google/react-native-make-payment

You can also try out the example by running the following command from the example directory:

npx react-native run-android

Configuration

To enable Google Pay in your app, you need to add the following Google Pay API meta-data element to the <application> element of your project's AndroidManifest.xml file (typically android/app/src/main/AndroidManifest.xml):

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

For production, you will also need to define the GOOGLE_PAY_ENVIRONMENT property in your project's gradle.properties file (typically android/gradle.properties):

GOOGLE_PAY_ENVIRONMENT=PRODUCTION

Usage

Following is a minimal example. A complete example can be found in example/src/App.tsx.

import { PaymentRequest } from '@google/react-native-make-payment';

const paymentDetails = {
  total: {
    amount: {
      currency: 'USD',
      value: '14.95',
    },
  },
};

const googlePayRequest = {
  // Google Pay API JSON request object, see:
  // https://developers.google.com/pay/api/android/reference/request-objects
};

const paymentMethods = [
  {
    supportedMethods: 'google_pay',
    data: googlePayRequest,
  },
];

const paymentRequest = new PaymentRequest(paymentMethods, paymentDetails);

paymentRequest.canMakePayment().then((canMakePayment) => {
  if (canMakePayment) {
    paymentRequest.show().then((response) => {
      // Handle PSP response
    });
  } else {
    // Google Pay unavailable
  }
});

Google Pay Button

Example of adding a native Google Pay button:

<GooglePayButton
  style={styles.googlepaybutton}
  onPress={checkCanMakePayment}
  allowedPaymentMethods={googlePayRequest.allowedPaymentMethods}
  theme={GooglePayButtonConstants.Themes.Dark}
  type={GooglePayButtonConstants.Types.Buy}
  radius={4}        
/>
