System hooks

DETAILS: Tier: Free, Premium, Ultimate Offering: Self-managed

System hooks (not to be confused with server hooks or file hooks) perform HTTP POST requests and are triggered on the following events:

• group_create
• group_destroy
• group_rename
• key_create
• key_destroy
• project_create
• project_destroy
• project_rename
• project_transfer
• project_update
• repository_update
• user_access_request_revoked_for_group
• user_access_request_revoked_for_project
• user_access_request_to_group
• user_access_request_to_project
• user_add_to_group
• user_add_to_team
• user_create
• user_destroy
• user_failed_login
• user_remove_from_group
• user_remove_from_team
• user_rename
• user_update_for_group
• user_update_for_team

The triggers for most of these are self-explanatory, but project_update and project_rename require clarification:

• project_update triggers when an attribute of a project is changed (including name, description, and tags) except when the path attribute is also changed.
• project_rename triggers when an attribute of a project (including path) is changed. If you only care about the repository URL, just listen for project_rename.

user_failed_login is sent whenever a blocked user attempts to sign in and is denied access.

As an example, use system hooks for logging or changing information in an LDAP server.

You can also enable triggers for other events, such as push events, and disable the repository_update event when you create a system hook.

NOTE: For push and tag events, the same structure and deprecations are followed as project and group webhooks. However, commits are never displayed.

Create a system hook

• Name and Description introduced in GitLab 16.9.

To create a system hook:

1. On the left sidebar, at the bottom, select Admin.

2. Select System hooks.

3. Select Add new webhook.

4. In URL, enter the URL of the webhook endpoint. The URL must be percent-encoded if it contains one or more special characters.

5. Optional. In Name, enter the name of the webhook.

6. Optional. In Description, enter the description of the webhook.

7. Optional. In Secret token, enter the secret token to validate requests.

   The token is sent with the webhook request in the X-Gitlab-Token HTTP header. Your webhook endpoint can check the token to verify the request is legitimate.

8. In the Trigger section, select the checkbox for each GitLab event you want to trigger the webhook.

9. Optional. Clear the Enable SSL verification checkbox to disable SSL verification.

10. Select Add system hook.
