Overview

A REST API (Representational State Transfer) is a popular architectural style for designing APIs and web services. It enables communication between client and server through standard HTTP methods such as GET, POST, PUT, DELETE, and PATCH to transfer data.

REST APIs are stateless, meaning the server does not store any information about the client between requests. This stateless nature makes REST APIs easier to maintain and scale.

HTTP Methods

HTTP Method	Usage
GET /users	Retrieve a list of users.
POST /users	Create a new user.
PUT /users/{id}	Update the information of a specific user.
DELETE /users/{id}	Delete a user.

HTTP Status Codes

HTTP status codes are issued by a server in response to a client’s request made to the server. They provide information about the outcome of the request. Here’s a table of some common HTTP status codes and their descriptions:

Status Code	Description
100	Informational
200	Successful
300	Redirection
400	Client Error
500	Server Error
