import { GooglePay } from 'react-native-google-pay';

const allowedCardNetworks = ['VISA', 'MASTERCARD'];
const allowedCardAuthMethods = ['PAN_ONLY', 'CRYPTOGRAM_3DS'];

const requestData = {
  cardPaymentMethod: {
    tokenizationSpecification: {
      type: 'PAYMENT_GATEWAY',
      // stripe (see Example):
      gateway: 'stripe',
      gatewayMerchantId: '',
      stripe: {

    if (ready) {
      // Request payment token
      GooglePay.requestPayment(requestData)
        .then((token: string) => {
