Have you tested API through Postman?

Yes, API testing through Postman is a standard practice. In Postman, you can create request collections with different methods (GET, POST, PUT, DELETE), set parameters, headers, and request body. It is also convenient to write scripts in JavaScript to verify responses, such as checking the status code, response content, and response time.

Example of a simple test in Postman:

pm.test("Status code is 200", function () {
    pm.response.to.have.status(200);
});

This allows automating the verification of API correctness and quickly identifying errors.
