What is JSON/REST?

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write, and easy for machines to parse and generate. It is often used to transmit data between a server and web application, serving as an alternative to XML. REST (Representational State Transfer) is an architectural style for designing networked applications. RESTful applications use HTTP requests to GET, PUT, POST, and DELETE data. REST and JSON are often used together, with JSON being the common format for the data exchanged in RESTful APIs. Thus, 'JSON/REST' typically refers to RESTful APIs that use JSON for request and response bodies.
