braintree-web/google-payment

A component to integrate with Google Pay. The majority of the integration uses Google's pay.js JavaScript file. The Braintree component generates the configuration object necessary for Google Pay to initiate the Payment Request and parse the returned data to retrieve the payment method nonce which is used to process the transaction on the server.

Examples

Simple Example 

// include https://payments.developers.google.com/js/apis/pay.js in a script tag
// on your page to load the `google.api.PaymentsClient` global object.

var paymentButton = document.querySelector('#google-pay-button');
var paymentsClient = new google.payments.api.PaymentsClient({
  environment: 'TEST' // or 'PRODUCTION'
});

braintree.client.create({
  authorization: 'tokenization-key-or-client-token'
}).then(function (clientInstance) {
  return braintree.googlePayment.create({
    client: clientInstance
  });
}).then(function (googlePaymentInstance) {
  paymentButton.addEventListener('click', function (event) {
    var paymentDataRequest;

    event.preventDefault();

    paymentDataRequest = googlePaymentInstance.createPaymentDataRequest({
      merchantId: 'your-merchant-id-from-google',
      transactionInfo: {
        currencyCode: 'USD',
        totalPriceStatus: 'FINAL',
        totalPrice: '100.00'
      }
    });

    paymentsClient.loadPaymentData(paymentDataRequest).then(function (paymentData) {
      return googlePaymentInstance.parseResponse(paymentData);
    }).then(function (result) {
      // send result.nonce to your server
    }).catch(function (err) {
      // handle err
    });
  });
});
