Introduction to the REST API

A REST (REpresentational State Transfer) API is an architectural style for an application program interface (API) that uses HTTP requests (GET, PUT, POST, DELETE) and a URI (resource identifier) to access and use data. There is no official standard for REST API however, the OpenAPI specification has become a common standard.
