# System hooks **(FREE SELF)**

Your GitLab instance can perform HTTP POST requests 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_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` deserve some clarification: `project_update` is fired any time
an attribute of a project is changed (including name, description, and tags)
_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 sign in and is
denied access.

System hooks can be used, for example, for logging or changing information in an
LDAP server.

In addition to these default events, you can enable triggers for other events,
such as push events, and disable the `repository_update` event
when you create a system hook.

NOTE:
We follow the same structure and deprecations as [Webhooks](../user/project/integrations/webhooks.md)
for Push and Tag events, but we never display commits.

## Create a system hook

To create a system hook:

1. On the top bar, select **Menu > Admin**.
1. On the left sidebar, select **System Hooks**.
1. Provide the **URL** and **Secret Token**.
1. Select the checkbox next to each optional **Trigger** you want to enable.
1. Select **Enable SSL verification**, if desired.
1. Click **Add system hook**.

## Hooks request example

       "project_visibility": "internal",
  "old_path_with_namespace": "jsmith/overscore"

Note that `project_rename` is not triggered if the namespace changes.
Please refer to `group_rename` and `user_rename` for that case.

## Local requests in system hooks

[Requests to local network by system hooks](../security/webhooks.md) can be allowed
or blocked by an administrator.

<!-- ## Troubleshooting

Include any troubleshooting steps that you can foresee. If you know beforehand what issues
one might have when setting this up, or when something is changed, or on upgrading, it's
important to describe those, too. Think of things that may go wrong and include them here.
This is important to minimize requests for support, and to avoid doc comments with
questions that you know someone might ask.

Each scenario can be a third-level heading, e.g. `### Getting error message X`.
If you have none to add when creating a doc, leave this section in place
but commented out to help encourage others to add to it in the future. -->
