Slack Service

On Slack

To enable Slack integration you must create an incoming webhook integration on Slack:

  1. Sign in to Slack
  2. Visit Incoming WebHooks
  3. Choose the channel name you want to send notifications to.
  4. Click Add Incoming WebHooks Integration
  5. Copy the Webhook URL, we'll need this later for GitLab.

On GitLab

After you set up Slack, it's time to set up GitLab.

Go to your project's Settings > Services > Slack and you will see a checkbox with the following events that can be triggered:

  • Push
  • Issue
  • Merge request
  • Note
  • Tag push
  • Build
  • Wiki page

Bellow each of these event checkboxes, you will have an input field to insert which Slack channel you want to send that event message, with #general being the default. Enter your preferred channel without the hash sign (#).

At the end, fill in your Slack details:

Field Description
Webhook The incoming webhook URL which you have to setup on Slack.
Username Optional username which can be on messages sent to slack. Fill this in if you want to change the username of the bot.
Notify only broken builds If you choose to enable the Build event and you want to be only notified about failed builds.

After you are all done, click Save changes for the changes to take effect.

Note: You can set "branch,pushed,Compare changes" as highlight words on your Slack profile settings, so that you can be aware of new commits when somebody pushes them.
