I have created an ASP.NET Web API and applied Authorize attribute to the API controller. Now, I want to test it using Postman but I am getting Authorization error.
In addition to the answer posted by Mathieu, I had to install interceptor extension for postman (https://www.getpostman.com/docs/interceptor_cookies, https://www.getpostman.com/docs/capture) to capture the cookies. After that it worked.
