Hello, I'm having a hard time with figuring out the right way to approach handling in app purchases for users with multiple accounts. I am using Appengine Endpoints to implement my server side API. This API returns some data to my users. As soon as user purchases a certain product API will return additional data. I want to make it more secure by enabling OAuth authentication to my endpoints. So as soon as user purchases something it is verified and remembered on a server. Thus my API endpoint will always know what data to return to a particular user.
But what should I do if a user has more than one account? I couldn't find the way how to obtain account the app uses for IAP (according to documentation it's the account used to download the app). So I either have to blindly pick first account or let user pick an account. But what if they pick another account and all their purchases would go to a different account? This creates a lot of problems. For instance if user has only one account on another device it will either not have server side info available or will not have Google Play recognizing as a buyer. Basically we will end up with two sources of info - Google Play and my server possibly conflicting with each other because of accounts. What makes problem even harder is that I don't want to force users logging in using their account as this really doesn't add much value to app at the moment. But at the same I want to avoid just sending purchased flag to my API based on some my local data (which can be compromised). What is the appropriate strategy for handling this I would say quite common situation? If only there was a way to know for sure which account the app used for purchases, all my problems would be gone.
