RESTful API

REpresentational State Transfer (REST) is an architectural-style Application Programming Interface (API) that centers around manipulating resources. RESTful APIs boil down to a simple request-and-response pattern. Brands interact with a RESTful API by using a program that uses the API to request data from the server. Then, the API returns data from the server, and the client displays the results to the user. These requests are generally made using the Hyper-Text Transfer Protocol (HTTP).

Web applications often use RESTful APIs in development because they’re highly scalable, flexible, and easy to modify or extend.
