To start processing Google Pay payments, you must first integrate directly with Google. Once integration is complete, you can add the Google Pay button to your checkout page and start requesting your customers' encrypted payment information.
Google Pay integration and payments can be simplified into following steps:
Step 1: Integrate with Google Pay
Before going live, you are required to register with Google Pay and select Solid as your payment processor. You will also need to whitelist your domain here. Note that you must be logged in as a Google Developer to do this. If not, you will be redirected to Google Pay's support page.
When you submit a payment data request to the Google API, be sure to include the following parameters:
'gatewayMerchantId': '<replace with key from SOLID>'
