# 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
**Request Header**:
## Verify an SSL certificate
```plaintext
By default, the SSL certificate of the webhook endpoint is verified based on
X-Gitlab-Event: Subgroup Hook
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",
> [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/20338) in GitLab 11.3.
"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"
}
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
- Your endpoint should send its HTTP response as fast as possible. If the response
X-Gitlab-Event: Subgroup Hook
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",
Relative image references are rewritten to use an absolute URL
"updated_at":"2021-01-20T09:40:12Z",
in the body of a webhook.
"event_name":"subgroup_destroy",
For example, if an image, merge request, comment, or wiki page includes the
"name":"subgroup1",
following image reference:
"path":"subgroup1",
"full_path":"group1/subgroup1",
"group_id":10,
"parent_group_id":7,
"parent_name":"group1",
"parent_path":"group1",
"parent_full_path":"group1"
}
```markdown
```
```
NOTE:
If:
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.
**Request Header**:
- GitLab is installed at `gitlab.example.com`.
- The project is at `example-group/example-project`.
```plaintext
The reference is rewritten in the webhook body as follows:
