GitLab Events

The built-in GitLab Events trigger initiates a flow when it receives a signal from a GitLab webhook.

Add the GitLab Events trigger to the canvas

  1. Go to the Triggers panel in the palette, expand the App Triggers section and drag the trigger onto the canvas.
  2. Double-click the trigger (or click the pencil icon).
  3. Set the authenticating user, and then copy the URL — you'll use this to set up the webhook in GitLab. Alternatively, you can create an integration user to use as the authenticating user.

  4. Click the Flood Control tab to edit the trigger's default flood control settings. For more information about these settings, see Trigger Flood Control.
  5. Click Done.
  6. On the flow canvas, connect the steps you want to run when xMatters receives a request to that URL.

You're now ready to configure GitLab to target the trigger.

Configure GitLab to send requests to the trigger URL

To have GitLab send alerts to the flow trigger, you need to configure a webhook and set it to use the trigger URL.

  1. In GitLab, go to Settings > Webhooks.

  2. On the Webhooks page fill in the following fields: 
    • URL: Paste the trigger URL you copied from Flow Designer.
    • Add the target names of any recipients you want to notify when the alert fires to the end of the URL.
      • For URL authentication, use an ampersand to attach recipients. For example, if you want to notify Emma Pearson and the on-call members in the group responsible for the Antares service, you'd add &recipients=epearson,antares to the URL.
      • For other authentication types, use a question mark to attach recipients. For example, if you want to notify Barry Gull and the on-call members in the group responsible for the Cassiopeia service, you'd add ?recipients=bgull,cassiopeia to the URL.
      • You must URL-encode any special characters or spaces in the target names.
    • Select the type of GitLab events that will send changes to xMatters. The following event types are supported: 
      • Push events
      • Merge request events
      • Job events
      • Pipeline events
      • Deployment events
      • Feature flag events
      • Releases events
    • Leave Enable SSL verification selected.

  3. Click Add webhook.

You're ready to use the webhook to trigger automated flows, including steps such as sending alerts and initiating incidents, though we always recommend testing before putting things into use.

The trigger has the following outputs you can use as inputs to steps further along the flow.
