What is difference between REST API and JSON?

JSON is based on a subset of the JavaScript Programming Language. Representative State Transfer (REST) is a client-server architectural style that uses the HTTP protocol in a simple and effective way. Systems that adhere to REST practices are often referred to as RESTful interfaces.

REST vs RESTful: Architecture The REST API follows all the rules of the REST Architecture . It has a client-server, stateless, cacheable, layer system with a uniform interface, whereas the RESTful web applications have all the features of the REST architecture with unique additional features.

A RESTful API is an architectural style for an application program interface (API) that uses HTTP requests to access and use data . That data can be used to GET, PUT, POST and DELETE data types, which refers to the reading, updating, creating and deleting of operations concerning resources.

One of the key advantages of REST APIs is that they provide a great deal of flexibility . Data is not tied to resources or methods, so REST can handle multiple types of calls, return different data formats and even change structurally with the correct implementation of hypermedia.
