Unity - Unlock ingame stuff for patreons


I have a patreon page and I am developing a game in Unity.
I would like to give my patreons cool stuff for free ingame (depending on the tier of subscription if possible).

Unfortunately I have no idea on how to do or approach this.

Basically what I need is a function that returns a boolean if the user is a patreon to my page. (or an integer/string depending on what tier he supports with)

Can someone help me with this?

Thank you very much!

There are various other threads talking about various implementations which you can use in accomplishing this. An example:

Basically you either need to have constant online connectivity, or, have to regularly fetch and save patron info if your game is offline.

Handling credentials is also discussed in the above thread. There should even be a case about handling creators’ tokens en masse.
