APIs are properties and methods provided by GAM so that applications can interact with it. It allows for communication with the GAM database, which is the one containing users, roles, and so on. 

In this video we will examine and implement two requirements to apply an event: one that allows users to anonymously log into the application and mark favorite sessions; later on, when a user registers, his/her favorite sessions are automatically associated with the logged in user. The second requirement is that only users with event organizer roles can view and run CRUD operations on the speakers' data from the device itself.
