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

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

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

After logging in 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 in the Authorization tab (I’ve tried ‘No Auth’ and ‘Basic Auth’)?
