What is REST API?
A REST API is an application programming interface in which the API follows REST design principles or an architectural style of representational state transfer. The REST API provides developers with a high level of flexibility and freedom, which has become the standard way to connect components and applications in a microservice architecture. The REST API is the browser and programming language independent. REST API clients communicate via HTTP protocol to perform standard CRUD operations within a resource.
What is an API?
An Application Programming Interface (API) is a computational interface that describes how multiple software components interact with each other and allows applications to exchange data between them. The APIs are standard-compliant (REST and HTTP), developer and automation-friendly, and easy to test. APIs are usually well documented to use and suitable for version control.
What is REST?
REpresentational State Transfer is an architectural style that enforces standards compliance between computer systems to make it easier for systems to interact with each other. REST has its own set of rules and constraints, just like other architectural styles.
How to test a REST API?
