endpoint is 100% correct. Our old integrations run well.

Answer 1

Goto Project Settings > Integrations and scroll down all the way. You will find "Slack Notifications". Use this to send notifications.

Answer 2

This is followed by gitlab-ce issue 41853

I get this error when i try to configure slackhook url within gitlab slack integration as a webhook.

Appears to have stopped working back in February 2018. Before that, everything worked fine.

Note: that same issue also mentions:

We were creating a new webhook. After I had a look at the tutorial again I started to use the Slack Notifications, which works on our projects.
