What is REST API Java?

What is REST API example?

Examples: a GET request to /user/ returns a list of registered users on a system. a POST request to /user/123 creates a user with the ID 123 using the body data. a PUT request to /user/123 updates user 123 with the body data.

What is swagger API?

This file is essentially a resource listing of your API which adheres to OpenAPI Specification.

What is REST API and how it works?

A REST API works in a similar way. You search for something, and you get a list of results back from the service you’re requesting from. The developer creates the API on the server and allows the client to talk to it. REST determines how the API looks like. It stands for “Representational State Transfer”.

Why is REST API used?
