REST API (Representational State Transfer Application Programming Interface) is a structured set of rules and protocols that allow you to interact with web servers and exchange data over the Internet. The REST API is based on the principle of “resources” which means that each application component (for example, a database object) is represented as a unique URL (resource), and interaction with these resources is carried out using standard HTTP requests such as GET, POST, PUT, and DELETE.
The REST API facilitates the creation of applications that can exchange data with other applications regardless of their programming language or platform. This makes it a popular tool for developing websites, mobile applications, and other applications that require external access to data or functionality from other systems over the Internet.
