I am trying to implement Google Pay payments into a mobile app. When requesing a google pay payment token, it is necessary to specify a gateway and gateway merchant ID, however Google Pay does not give any guidance in documentation for what should go in those fields when using Authorize.Net as a payment gateway. It does support direct tokenization however, which requires a public encryption key be sent with payment token requests. Is there a payment gateway merchant ID I can use with Google Pay and Authorize.Net, or do I need to use direct tokenization, and if it must be the latter, how do I get a public encryption key from Authorize.Net so that when I use the gateway, they will be able to decrypt it to process the payment?
