How do I define a JSONRequests Variable in C++?

I’m building my own gameinstance and I need to add a variable to the C++ class so I can save a JSONRequest variable. In blueprints, it’s listed in the Variable Types as “JSONRequest” but I can’t find anything about this variable type.

Also when I do a find on the whole code base nothing comes back for it. So where is it magically hiding?

I’d really appreciate any information on this so I can keep moving.

Didn’t realize it, but the JSONRequest was a blueprint. Ok, that expains alot.
