Viewing post in [Help] How to check players own a key of my game?

Sorry for my confusing sentences I usually create most of the time.

https://itch.io/api/1/KEY/game/GAME_ID/download_keys looks like this thing is the best option. Okay, if I own a itch.io game, it will generate a download key for the player. (1) How is it's response if player owns the game?

But now if I send this - https://itch.io/api/1/KEY/game/GAME_ID/download_keys http request from my game, user may always see error:{ invalid } . Because itch.io doesn't knows who is the user, as he/she isn't logged in inside my game. But what I want is now get user logged in my game and than check his name from log in information. And than I want to check if he bought my game by sending http request to itch.io.

Now my problem with this method is how to do a login check with itch.io. So if it's the real itch.io user, than the game continues to check if that user bought the game. If he has the key, than game starts. (2) Is there a login system of itch.io to put it in my C# game ?

(3) Do you think OAuth may be better? I checked it a bit before. But itch.io API would also be easier than OAuth. As I expect player is using itch.io apps. But (4) recommend me your opinion, should I do with the login thing or look for OAuth ...

Also, thanks for your timely previous response, I thought none would answer anything.
