GitLab

System hooks

Your GitLab instance can perform HTTP POST requests on the following events:

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

The triggers for most of these are self-explanatory, but project_update and project_rename deserve some clarification: project_update is fired any time an attribute of a project is changed (name, description, tags, etc.) unless the path attribute is also changed. In that case, a project_rename is triggered instead (so that, for instance, if all you care about is the repository URL, you can just listen for project_rename).

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

System hooks can be used, e.g. for logging or changing information in a LDAP server.

NOTE: Note: We follow the same structure and deprecations as Webhooks for Push and Tag events, but we never display commits.
