How to check transaction is genuine or not? about android-monetizeapp

@aman811 there is no need to put your Base64 public key anywhere in the app. This was handled by Play Billing Library itself. All the Purchase flows are handled in BillingManager. However, if you need to verify the purchase, whether genuine, you can do it on the server side.

@svignesh93 I see.. Thanks for your help.. Do you know a reliable PHP backend code source for this? Because I have been reading ambiguous statements. One says the Base64 key is used when used within the app, and for the server, we need to create refresh_token / access_token which expires every 60 minutes. More on this: https://developers.google.com/android-publisher/authorization

Any help would be appreciated.

@aman811 I'm sorry that I have not done any implementation on the server side, for this app. I focused only on the client side implementation.
