What is a Representational State Transfer (REST) API?
A Representational State Transfer (REST) API is one that exposes its functionality and resources through a CRUD (Create, Read, Update and Delete) interface over standard HTTP requests. REST APIs offer their resources at a specified URL, which can include JSON, HTML, images and audio files.
Each REST API defines the HTTP methods that can be acted on it. The most common method is GET, which retrieves a resource from a server much like a web browser retrieves a web page. Almost all REST APIs support the GET method. A REST API can also offer a POST method for creating a new resource on the server and a PUT method for updating a resource. Also possible is a DELETE method, which deletes a resource from a server.
While you can make REST calls directly in a web browser, the APIs are mostly used by applications, which use them to obtain resources that they require.
