Custom GPT - API Auth not working

I’m trying to make a custom gpt that will allow me to easily add notes to a contact/deal/company and add leads, etc.
i’m having problems with authentication - can you please help?
So far i’ve reached “app not found” screen :confused:

Hello @tomasz_00 , welcome to the community!

That depends on many things, can you share more details? On which step of the authentication you are, and what information are you sending on the request?
