Have you used Postman or Swagger UI for API testing?

Yes, Postman and Swagger UI are popular tools for testing and documenting APIs.

• Postman allows creating and executing HTTP requests with various methods, configuring headers, request body, parameters, and also saving request collections for reuse. This is convenient for manual API testing, debugging, and automation.

• Swagger UI is an interactive documentation generated based on the OpenAPI specification. It enables viewing endpoint descriptions, parameters, data models, and executing requests directly from the browser.

Using these tools helps to find errors faster, verify API correctness, and facilitates communication between developers and analysts.
