Introduction

GooglePay is a type of Digital Wallet and acts as a virtual Payment Device, by allowing C9PG access to logged in customers’ payment information, stored in their Google Account.

C9PG uses secure credentials to obtain the payment data, which is then used with the relevant merchant account.

The merchant account is selected normally, with the GMID.

Here is an example of the Google Pay JSON transaction:

 {

                “Medium”“Credit”,
                “CardPresent”“N”,
                “GMID”“2001008149”,
                “GTID”“GT3010023905”,
                “MerchantID”“123456”,
                “MerchantName”“Cloud9”,
                “TransType”“Sale”,
                “MainAmt”“16000”,
                “TipAmt”“0”,
                   “InvoiceNum”:”1233434″
            };

Getting Started with Google Pay

The first step is to register with the Google Pay Business Console and receive a Google merchant ID.  Please, contact us for more info
