HATEOAS
HATEOAS, an abbreviation for Hypermedia As The Engine Of Application State, is a constraint of the RESTful application architecture that distinguishes it from most other network application architectures.
The principle is that a client interacts with a network application entirely through hypermedia provided dynamically by application servers. A REST client needs no prior knowledge about how to interact with any particular application or server beyond a generic understanding of hypermedia.
By contrast, in some service-oriented architectures (SOA), clients and servers interact through a fixed interface shared through documentation or an interface description language (IDL).
The HATEOAS constraint decouples client and server in a way that allows the server functionality to evolve independently.
