Quick Introduction: I'm new to the Partners API which is using Graphiql. Till now I was using the REST API (with PHP) for building applications. This is my first time with Graphiql and from the docs, I do not understand how to work with it.
Description: I have made a quick function in PHP to access the Partners API via curl and everything is working fine, but when I start building queries I do not know how to retrieve the data I want. I have tested the functionality and it works fine with basic information - retrieving the API Key from Application with ID.
