react-native-make-payment

Adds native payments using the W3C Payment Request API to your React Native app. Currently supports Google Pay on Android.

Installation

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

You can also try out the example by running the following command from the root of this repo:

yarn && yarn example

Configuration

For production, you will 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}        
/>
