MS connection with Check MK webhooks

CMK version: Enterprise
OS version: Version: 2.3.0p20

Hi everyone!

This is my first post in the community.

I’ve been assigned to implement the notifications connection between Microsoft teams and Check MK Enterprise.

I have used the following document to implement this Teams Notification

But I’m not seeing any errors, but I’m not receiving the notification in the channel that I set for this purpose.

This is how is set the notification in CMK:

Please note that there seem to be differences between version 2.3 and 2.4.
I haven’t tested it with 2.4 yet, but in 2.3 you still have to enter a contact so that the notification is sent to Teams:

And keep in mind that “Test Notification” does not send a notification to teams, but only checks whether rules apply.
To actually send test notifications via this notification method, you must continue to use Fake check results in Checkmk 2.3.0.

See Docs for 2.3:
