What is rest API?

Question

What is rest API? i want authentication in api

Answer 1

REST: REpresentative State Transfer.
API: Application Programming Interface.

A REST API is essencially a way for computer programs to talk to each other. For example, when you login to SoloLearn, your web browser sends your email and password over to SoloLearn's servers, and if the two match on its servers then SoloLearn allows you to login and access the platform. This is possible thanks to an API.

One of the most common REST APIs is called HTTP or "Hypertext Transfer Protocol", which sends things over the web; I'm sure you're familiar with the "http" that precedes almost all URLs.

HTTP has several methods, which are ways of interacting with data. The 4 basic ones are:
- POST (creates a new resource to the server, like when you post a new question in SoloLearn)
- GET (reads a resource from the server, like the answers of the sololearners on your question)
- PUT (updates a resource on the server, say you want to edit your question or answer you already sent)
- DELETE (deletes a resource on the server, for example if you delete this question)
