REST APIs

A REST API, also known as a RESTful API (Representational State Transfer Application Programming Interface), is a set of definitions and protocols for building and integrating application software. It follows the REST standards and uses HTTP requests to GET, PUT, POST, and DELETE data. In geneal, a REST API is a set of remote calls that uses standard methods to request and return data in a specific format between two systems.
