# Webhook events **(FREE)**
You can configure a [webhook](webhooks.md) in your project that triggers when
an event occurs. The following events are supported.
## Push events
Triggered when you push to the repository except when pushing tags.
NOTE:
When more than 20 commits are pushed at once, the `commits` webhook
attribute only contains the newest 20 for performance reasons. Loading
detailed commit data is expensive. Note that despite only 20 commits being
present in the `commits` attribute, the `total_commits_count` attribute contains the actual total.
NOTE:
If a branch creation push event is generated without new commits being introduced, the
`commits` attribute in the payload is empty.
Also, if a single push includes changes for more than three (by default, depending on

}
```
### Subgroup events **(PREMIUM)**
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/260419) in GitLab 13.9.
Subgroup events are triggered when:
- A [subgroup is created in a group](#subgroup-created-in-a-group)
- A [subgroup is removed from a group](#subgroup-removed-from-a-group)
#### Subgroup created in a group
You can specify a secret token to validate received payloads.
The token is sent with the hook request in the
`X-Gitlab-Token` HTTP header. Your webhook endpoint can check the token to verify
that the request is legitimate.
**Request Header**:
## Verify an SSL certificate
```plaintext
X-Gitlab-Event: Subgroup Hook
```
By default, the SSL certificate of the webhook endpoint is verified based on
an internal list of Certificate Authorities. This means the certificate cannot
be self-signed.
**Payload example**:
You can turn off SSL verification in the [webhook settings](#configure-a-webhook)
in your GitLab projects.
```json
{
## Filter push events by branch
"created_at":"2021-01-20T09:40:12Z",
"updated_at":"2021-01-20T09:40:12Z",
"event_name":"subgroup_create",
"name":"subgroup1",
"path":"subgroup1",
"full_path":"group1/subgroup1",
"group_id":10,
"parent_group_id":7,
"parent_name":"group1",
"parent_path":"group1",
"parent_full_path":"group1"
> [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/20338) in GitLab 11.3.
}
```
Push events can be filtered by branch using a branch name or wildcard pattern
to limit which push events are sent to your webhook endpoint. By default,
all push events are sent to your webhook endpoint. You can configure branch filtering
in the [webhook settings](#configure-a-webhook) in your project.
#### Subgroup removed from a group
## HTTP responses for your endpoint
**Request Header**:
If you are writing your own endpoint (web server) to receive
GitLab webhooks, keep in mind the following:
```plaintext
X-Gitlab-Event: Subgroup Hook
```
- Your endpoint should send its HTTP response as fast as possible. If the response
takes longer than the configured timeout, GitLab assumes the hook failed and retries it.
To customize the timeout, see
[Webhook fails or multiple webhook requests are triggered](#webhook-fails-or-multiple-webhook-requests-are-triggered).
- Your endpoint should ALWAYS return a valid HTTP response. If not,
GitLab assumes the hook failed and retries it.
Most HTTP libraries take care of the response for you automatically but if
you are writing a low-level hook, this is important to remember.
- GitLab ignores the HTTP status code returned by your endpoint.
**Payload example**:
## How image URLs are displayed in the webhook body
```json
{
> Introduced in GitLab 11.2.
"created_at":"2021-01-20T09:40:12Z",
"updated_at":"2021-01-20T09:40:12Z",
"event_name":"subgroup_destroy",
"name":"subgroup1",
"path":"subgroup1",
"full_path":"group1/subgroup1",
"group_id":10,
"parent_group_id":7,
"parent_name":"group1",
"parent_path":"group1",
"parent_full_path":"group1"
Relative image references are rewritten to use an absolute URL
in the body of a webhook.
For example, if an image, merge request, comment, or wiki page includes the
following image reference:
}
```markdown
```
NOTE:
Webhooks for when a [subgroup is removed from a group](#subgroup-removed-from-a-group) are not triggered when a [subgroup is transferred to a new parent group](../../group/index.md#transfer-a-group)
### Feature Flag events
Triggered when a feature flag is turned on or off.
If:
**Request Header**:
- GitLab is installed at `gitlab.example.com`.
- The project is at `example-group/example-project`.
```plaintext
X-Gitlab-Event: Feature Flag Hook
```
The reference is rewritten in the webhook body as follows:
