What is hypermedia REST API?
Hypermedia REST APIs use links to point to related resources and to possible resource state transitions. This makes REST APIs discoverable and reduces coupling between clients and the server. Clients can interact with links provided by the server instead of constructing URIs on their own.

Should you decouple client and server when implementing a hypermedia API?
While decoupling client and server is a very worthwhile goal, when implementing a hypermedia API you may stumble over a few things. First of all, the decoupling aspect of the hyperlinks gets lost if the client chooses not to evaluate the hyperlinks but instead uses hard-coded URLs to access the API.
