Can't get notifications via Slack webhook to work

Thank you, Simon-Meuller, I read that page you sent, it did have some insight for me, which was good, but I would argue that I am not mixing up the two, in this case. As the article says, “When a host’s condition changes, (e.g. from OK to CRIT ), Checkmk registers an event.” and I feel like I have configured the notifications to notify on such an event, like going from OK to CRIT. Unless I am still missing the point completely, I apologize.

Thank you Andreas-Doehler, I’ve changed the notification log level, and I searched all around for the appropriate log file, but I am having troubles finding it… There is nothing related to webhooks… The mail.log doesn’t reference anything in there either… Is there a specific file I could look for?

Thanks
