REST APIs

What are REST APIs ?

REST stands for REpresentation State Transfer. It is one of the architectural designs for making APIs. This type of design can be easily identified as - When a backend server has REST API and you make client-side requests (from browser/application), then to this API your client is RESTful.

How do they work ?

REST heavily relies on HTTP. It has 4 essential operations: 

• GET - receiving data
• POST - creating new data
• PUT - updating data
• DELETE - deleting data

What are they used for ?

APIs are basically used to simplify programming by exposing elements of the database and fulfilling the actions/queries that the developer or user needs. If designed properly, these APIs can be very efficient and can even be used in the automation, customization and personalisation of applications.
