I’m trying to test ‘cookie authorization’ in my .NET 8 Web API with Postman.

I have an API Endpoint authtest that I can sucessfully hit.

When I add the [Authorize] attribute I get a 404 Not Found error.

Ater loggining with a Postman POST (with body) request to the login endpoint I grab the auth cookie:

Auth=CfDJ8Ays_KdJccNKsge90R84fh-gWHlRTEVth-34blhAW4EMO6RnHC . . .

In the Postman request to authtest I select Cookies, add a localhost Domain, and the auth cookie

Auth=CfDJ8Ays_KdJccNKsge90R84fh-gWHlRTEVth-34blhAW4EMO6RnHC . . .; Path=/; Secure; HttpOnly;

What am I missing? What AuthType should I choose under the Authorization tab (I’ve tried ‘No Auth’ and ‘Basic Auth’)?
