In this integration method you ned to implement a few steps:

Step 01: Setup

To process google pay payments, you will need to be sure that the terminals you want to use are configured for that, so:

• First, register with Google: In order to use the Google Pay API in Production, you must register with Google. To do this, simply navigate to the Google Payment API Support page. You will be asked to register the website you wish to make payments with, and Google will give you a Google Merchant ID which you will use during your Google Pay requests.

• Then, have your Google Pay details configured: Contact our support team and ask for Google Pay to be enabled on the desired terminals and then provide the Google Merchant ID that Google assigned to you.

Step 02: Integrate the Google Pay API to your website

The merchant’s developer team will need to implement the Google Payment API to the merchant website in order to retrieve the customers (encrypted) card details (to be informed as GOOGLEPAYLOAD).

Note that during your Google Pay API Request, you will need to specify the following details:

• merchantId - The Merchant ID given to you by Google
• gateway - “Nuvei” (but all lower case)
• gatewayMerchantId - The Merchant ID given to you by the gateway

Step 03: Send Payment Request

After you’ve retrieved the Google Payload, convert the users Google Pay data to Hexadecimal, place it in the XML Payment Request in the GOOGLEPAYLOAD tag, and send the XML Payment Request to our servers as normal.

Consult the XML Payment Features for details on the URL for the request and other body fields too. Using the example below (change the data inside the tags) shows you how to perform a simple transaction using google pay.
