I have the Unity Playfab SDK installed. I'm new to it so there is a chance I'm missing lots of things but still my question is how to use InternalTitleData. The first thing I tried is to call
PlayFabServerAPI.GetInternalTitleData() in script but there is no PlayFabServerAPI class. I tried to guess that is calling server API functions is dangerous for security reasons (may be I'm wrong) so I do not understand what should I do and how to use that?
And I want to describe what I want to achieve using InternalTitleData. We want to make our first release quite soon for alpha tests. I wanted to create some keys in InternalTitleData which are used to create new accounts for our game, because we need a limited amount of players for that. So I wanted to add a "KEY" field in registration form. That key is a thing only developers can give.
