  * HATEOAS:

    HATEOAS is an acronym for Hypermedia As The Engine Of Application State, it's the concept that when sending information over a RESTful API the document received should contain everything the client needs in order to parse and use the data i.e they don't have to contact any other endpoint not explicitly mentioned within the Document

  * OpenAPI Sepcifications (OAS)

    The OpenAPI Specification (OAS) defines a standard, language-agnostic interface to RESTful APIs which allows both humans and computers to discover and understand the capabilities of the service without access to source code, documentation, or through network traffic inspection. When properly defined, a consumer can understand and interact with the remote service with a minimal amount of implementation logic.

    An OpenAPI definition can then be used by documentation generation tools to display the API, code generation tools to generate servers and clients in various programming languages, testing tools, and many other use cases.
