RESTful API

RESTful API is a way of providing interoperability between computer systems on the internet. REST stands for Representational State Transfer. It is an architectural style for creating web services that rely on a stateless client-server protocol, almost always HTTP.

With RESTful APIs, clients make requests to retrieve or modify resources using a set of predefined operations. Resources are identified in the requests using URLs. The most common operations are GET, POST, PUT, PATCH, and DELETE. For example, a GET request to the URL https://api.example.com/users/123 would retrieve the user resource with ID 123. A POST request to https://api.example.com/users would create a new user. RESTful systems aim to provide performance, scalability, simplicity, modifiability, and reliability. They are commonly used in web and mobile applications to retrieve data from remote systems. A key advantage is that RESTful APIs make the client-server communication stateless. The server does not need to retain client state between requests, reducing load and improving scalability.
