```

## Usage
```javascript
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: {
        publishableKey: 'pk_test_TYooMQauvdEDq54NiTphI7jx',

  },
  merchantName: 'Example Merchant',
};

// Set the environment before the payment request
GooglePay.setEnvironment(GooglePay.ENVIRONMENT_TEST);

// Check if Google Pay is available
GooglePay.isReadyToPay(allowedCardNetworks, allowedCardAuthMethods)
  .then((ready) => {
    if (ready) {
      // Request payment token
      GooglePay.requestPayment(requestData)
        .then((token: string) => {
