What is RestAPI ?

RestAPI, or Representational State Transfer Application Programming Interface, is a set of rules and conventions for building and interacting with web services. It allows different software applications to communicate with each other over the internet.

RestAPIs are based on the principles of REST, which is an architectural style for designing networked applications. REST relies on a stateless, client-server communication pattern, and uses standard HTTP methods, such as GET, POST, PUT, and DELETE, to perform actions on resources.

One of the key features of RestAPIs is its ability to support multiple data formats, including XML and JSON. This flexibility allows developers to choose the format that best suits their needs when transferring data between the client and the server.

RestAPIs are commonly used in web development, especially in building applications with JavaScript frameworks like React. They are also widely used in mobile app development, and in integrating different web services with each other.

Overall, RestAPIs play a crucial role in enabling the seamless integration of different software applications, and are an essential part of modern web development.
