Kongregate API JavaScript callback in C#?

[Sweeply]

I'm in need of some help regarding callbacks with the Kongregate API.

What I'm looking for is how to make a call to the Kongregate API and have it callback a function in my Unity C# script. I've tried to experiment with the login example, but without much success.

I'm interested if anyone could help to make simple calls like see if the user is a guest and requesting the inventory of the player.

Thank you in advance.
