Have you had experience working with Swagger tool for API documentation?

Swagger is a tool for documenting REST APIs that allows for automatically generating interactive documentation based on the OpenAPI specification. It is convenient because developers and testers can see available endpoints, request parameters, data types, and response examples.

An example of using Swagger: a specification file (usually in YAML or JSON format) is created in the project, describing all API methods. Then, Swagger UI displays this information in a user-friendly web interface where requests can be tested immediately.

This significantly simplifies communication between teams and speeds up the testing and development process.
