restful api

A RESTful API (Representational State Transfer API) is a type of web API (Application Programming Interface) that uses HTTP requests to perform operations on data. It is based on REST architecture, which is a set of principles for building scalable and flexible web services.

RESTful APIs provide a standard way for different systems to communicate with each other over the internet. They use standard HTTP methods such as GET, POST, PUT, and DELETE to perform CRUD (Create, Read, Update, Delete) operations on resources.

RESTful APIs are stateless, meaning that the server does not maintain any session information. Instead, each request contains all the necessary information for the server to process it. This makes the API more scalable and easier to maintain.

RESTful APIs use JSON (JavaScript Object Notation) or XML (Extensible Markup Language) to represent data in a structured format. They also use hypermedia links to connect different resources and enable navigation between them.

Overall, RESTful APIs are a popular choice for building modern web applications due to their simplicity, flexibility, and scalability.
