Unity Android/IOS/Steam API+SDK Integration (backend)

I have a game that is almost finished, but we are struggling to finish the backend of it

So far we have the server already interacting with the game (to save & load player progression on it, with backup), as well as the Android IAP fully setup using an asset on the unity store.

We need to have the authentication setup for steam/android/IOS, as well as the IAP for steam/IOS

Skills: Unity 3D, iPhone, Android, Mobile App Development, Game Development
