# System hooks
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.
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. In the top navigation bar, go to **{admin}** **Admin Area**.
1. In the left sidebar, select **System Hooks**.
1. Provide the **URL** and **Secret Token**.
1. Select the check box next to each **Trigger** you want to enable.
1. Select **Enable SSL verification**, if desired.
1. Click **Add system hook**.

```
**Project renamed:**
```json

## 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. -->
