HATEOAS (Hypertext As The Engine Of Application State), o 2 RESTful , . 3 -> hypermedia controls Hypermedia controlsare the combinations of protocol methods and link relations in an hypermedia format that tells the client what state transitions are available and how to perform them.

Anhypermedia format defines the contract between client and server. It's the hyperlink-enabled data format you are using for a particular representation of a resource in an hypermedia application.The point of hypermedia controls is that they tell us what we can do next, and the URI of the resource we need to manipulate to do it.3
