What is Rest API.

A RESTful API is an application program interface (API) that uses HTTP requests to GET, PUT, POST, and DELETE data.

What is the Architecture of API

• HTTP headers used for authorization and generation of token it also has content-type mostly as application/JSON
• HTTP Request  (POST,GET,PUT,DELETE )
• Status Code/ Response Code :2XX,3XX,4XX,5XX
