Is it possible to connect Google Pay to the app?

Question

Google Play

Hello
I'm interested in the ability to connect Google PAY to an application that is distributed as an apk file and cannot be published in the PLAY Market. Are there any options?
Not a malware, but they don’t take it to the playmarket either)
I would like to connect it natively for android, and not through the web ...
By the way, it doesn’t work through the web view either)

No, you can't, until Google releases your application to the market, it will not give you a working key, and you will only be able to work with the test part of the Google Pay API

it is written what cannot be sold through Google Pay
