TM1 API CAM Authentification

Hi everyone,
did someone tried to authenticate using integrated mode 5, with CAM?
Any help with some more detailed steps than on IBM pages would be really helpful.
I tried combinations with encoding my username, password and namespace, but all returned 401 unauthorized. Also if someone was trying with CAM passport, any help is welcome. I am using Postman and I tried to follow CAMuri and send CAM Passport that I see in cookies after logging in, but that didn’t help either :confused:
Thanks.
