# Dashboard annotations API

> - [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 annotation will be displayed as single event at 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" \
