Online payments

You can accept payments through Google Pay™ via Checkout (Hosted Payments Page - HPP) or via eComm API.

Follow the integration steps below to process transactions via Verifone ecomm API.

Required fields

A Google Pay web integration consists of implementing both client-side and server-side components. You will need to implement the following:

• Configure the Verifone payment gateway ID and your merchant ID to initialize the Google pay client.

• Use the Google Pay token to make a wallet transaction API call and complete the session based on the response

Code sample

// Specify verifone as the gateway and define your wallet contract
const tokenizationSpecification = {
  type: 'PAYMENT_GATEWAY',
  parameters: {
    'gateway': 'verifone',
    'gatewayMerchantId': 'YOUR_WALLET_CONTRACT'
  }
};

// Specify your google pay merchant ID and name when setting up your paymentDataRequest
  paymentDataRequest.merchantInfo = {
    // @todo a merchant ID is available for a production environment after approval by Google
    // See {@link https://developers.google.com/pay/api/web/guides/test-and-deploy/integration-checklist|Integration checklist}
    merchantId: 'YOUR_MERCHANT_ID',
    merchantName: 'YOUR_MERCHANT_NAME'
  };

// Pass the google pay token to your server to make the wallet transaction API call
function onGooglePaymentButtonClicked() {
  const paymentDataRequest = getGooglePaymentDataRequest();
  paymentDataRequest.transactionInfo = getGoogleTransactionInfo();

  const paymentsClient = getGooglePaymentsClient();
  paymentsClient.loadPaymentData(paymentDataRequest)
      .then(function(paymentData) {
        // handle the response
  paymentToken = paymentData.paymentMethodData.tokenizationData.token;
      fetch("YOUR_SERVER", {
      method: "POST",
        headers: {"Content-Type": "application/json"},
        body: getPayload(JSON.parse(paymentToken)),
      }).then((res) => res.json())
        .then((res) => {
// handle wallet transaction response
          if (res.status.includes('AUTHORIZED')) {
          alert('Payment Successful');
          }
      })
         .catch((err) => console.log(err));
      })
      .catch(function(err) {
        // show error in developer console for debugging
        console.error(err);
      });
}
