Overview

The Google Pay API enables fast, simple checkout within your app/website, and gives you convenient access to hundreds of millions of cards saved to Google Accounts worldwide.

Supported payment card networks

VISA

MASTERCARD

How it works

Android

When a user taps the Google Pay payment button, they see a payment sheet that displays the payment methods saved to their Google Account, as well as optional fields such as a shipping address field. Users can quickly select a payment method, add an optional shipping address, or add new information.

The payment flow is as follows:

  1. The user taps the Google Pay payment button and sees a payment sheet with a list of supported payment methods.
  2. The user selects a payment method and Google Pay securely returns a payment token for that method to your app.
  3. Your app submits the payment token, along with details about the purchase, to its backend.
  4. To execute the payment, the backend processes the purchase and sends the payment token to the payment service provider.

Web

Web mode is compatible with iOS devices, Android devices, and PC browser devices.

Get started

Terms and conditions

By using Google Pay, the merchant needs to review and adhere to Google Pay API Terms of Service and Acceptable Use Policy.

Set up a Google Account

The merchant needs to register on Google Pay and Wallet Console. After registering successfully, Google will generate a Merchant ID.

1. Enter the merchant name

2. Configure Business Profile

3. View the Merchant ID

How to design the UI style?

Once you've integrated the Google Pay API, you need to get approval for all of the places where you display or reference Google Pay within your UI in order to gain production access.

Android

Web

The following guidelines show how to include the Google Pay brand within your websites. Please click here.

Integrate with Google Pay API

Android

Please follow the Android tutorial

About some key parameters, please follow the following descriptions.

Step 2: Request a payment token for your payment provider

private static JSONObject getGatewayTokenizationSpecification() throws JSONException {
    return new JSONObject() {{
      put("type", "PAYMENT_GATEWAY");
      put("parameters", new JSONObject() {{
        put("gateway", "cardinfolink");
        put("gatewayMerchantId", "{sid that is generated by EVONET}");
      }});
    }};
  }

📘

Note

If the acquirer's Google Pay Payment Gateway License is EVO Cloud, then the gateway is set as 'cardinfolink'. If other, then set as the acquirer's gatewayID.

Step 3: Define supported payment card networks

private static JSONArray getAllowedCardNetworks() {
  return new JSONArray()
      .put("MASTERCARD")
      .put("VISA");
}

📘

Note

Now EVONET supported payment card networks are VISA and MASTERCARD. The merchant can configure it according to the payment brands under the Google Pay Payment Brand.

Step 7: Create a PaymentDataRequest object

private static JSONObject getMerchantInfo() throws JSONException {
    return new JSONObject().put("merchantId", "{Merchant ID that is generated by Google}");
  }

Step 9: Handle the response object

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    switch (requestCode) {
      // value passed in AutoResolveHelper
      case LOAD_PAYMENT_DATA_REQUEST_CODE:
        switch (resultCode) {

          case Activity.RESULT_OK:
            PaymentData paymentData = PaymentData.getFromIntent(data);
            handlePaymentSuccess(paymentData);
                   //Make a Payment
            break;

          case Activity.RESULT_CANCELED:
            // The user cancelled the payment attempt
            break;

          case AutoResolveHelper.RESULT_ERROR:
            Status status = AutoResolveHelper.getStatusFromIntent(data);
            handleError(status.getStatusCode());
            break;
        }

        // Re-enables the Google Pay payment button.
        googlePayButton.setClickable(true);
    }
  }

Web

Please follow the web tutorial

About some key parameters, please follow the following descriptions.

Step 2: Request a payment token for your payment provider

const tokenizationSpecification = {
  type: 'PAYMENT_GATEWAY',
  parameters: {
    'gateway': 'cardinfolink',
    'gatewayMerchantId': '{sid that is generated by EVONET}'
  }
};

📘

Note

If the acquirer's Google Pay Payment Gateway License is EVO Cloud, then the gateway is set as 'cardinfolink'. If other, then set as the acquirer's gatewayID.

Step 3: Define supported payment card networks

const allowedCardNetworks = [ "MASTERCARD", "VISA"];

📘

Note

Now EVONET supported payment card networks are VISA and MASTERCARD. The merchant can configure it according to the payment brands under the Google Pay Payment Brand.

Step 8: Create a PaymentDataRequest object

paymentDataRequest.merchantInfo = {
  merchantName: '{Merchant Name}'
  merchantId: '{Merchant ID that is generated by Google}'
};

Step 9: Register an event handler for user gestures

paymentsClient.loadPaymentData(paymentDataRequest).then(function(paymentData){
  // if using gateway tokenization, pass this token without modification
  paymentToken = paymentData.paymentMethodData.tokenizationData.token;
// Make a Payment

}).catch(function(err){
  // show error in developer console for debugging
  console.error(err);
});

Make a Payment

The merchant should call the POST Payment API. Please refer to the following field descriptions.
