Is a developer's account blocked in the play market for payment in the application implemented by external services?

Question

Google Play

I will describe more specifically, there is an application, let's say, competing, it has the ability to turn off advertising for a fee, and this possibility is implemented bypassing the play market payment service. If I'm not mistaken, Google has strict requirements in this regard, so that payment is made only through the Play Market. Or did I not understand something?

Answer 1

depends on the implementation
last year for the client I connected paypal payment in the application
