Zammad integration

Hi There,

I’m trying to plug Check MK into Zammad.
The goal is to create ticket on Zammad when an incident comes on one of my server monitored by check mk.
I followed the official documentation to do this. They recommend to create an API on checkmk server, then to create notifications rules with those API . That’s what I have done.

But, and that’s the problem, once everything done, no tickets are opened on Zammad.
I am looking for logs on my CheckMK server but I dont know where that kind of events should be logged.
I seems that there is traffic between both servers

I’ve never been comfortable with the notifications mechanism and even less with the APIs.
So I guess I made something wrong in my notification setup.
But I don’t see where.
Has anyone tried this integration between Zammad and CheckMK and could help me?

Thanks
