# Dashboard annotations API **(FREE)**
> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/29089) in GitLab 12.10 behind a disabled feature flag.
Metrics dashboard annotations allow you to indicate events on your graphs at a single point in time or over a time span.
## Create a new annotation
```plaintext
POST /environments/:id/metrics_dashboard/annotations/
POST /clusters/:id/metrics_dashboard/annotations/
```
Parameters:
| Attribute | Type | Required | Description |
|:---------------|:---------------|:---------|:-----------------------------------------------------------------------------|
| `dashboard_path` | string | yes | ID of the dashboard which needs to be annotated. Treated as a CGI-escaped path, and automatically un-escaped. |
| `starting_at` | string | yes | Date time string, ISO 8601 formatted, such as `2016-03-11T03:45:40Z`. Timestamp marking start point of annotation. |
| `ending_at` | string | no | Date time string, ISO 8601 formatted, such as `2016-03-11T03:45:40Z`. Timestamp marking end point of annotation. When not supplied, an annotation displays as a single event at the start point. |
| `description` | string | yes | Description of the annotation. |
```shell
curl --header "Private-Token: <your_access_token>" "https://gitlab.example.com/api/v4/environments/1/metrics_dashboard/annotations" \
--data-urlencode "dashboard_path=.gitlab/dashboards/custom_metrics.yml" \
--data-urlencode "starting_at=2016-03-11T03:45:40Z" \
--data-urlencode "description=annotation description"
```
Example Response:
```json
{
"id": 4,
"starting_at": "2016-04-08T03:45:40.000Z",
"ending_at": null,
"dashboard_path": ".gitlab/dashboards/custom_metrics.yml",
"description": "annotation description",
"environment_id": 1,
"cluster_id": null
