# Annotations API

Annotations are saved in the Grafana database (sqlite, mysql or postgres). Annotations can be organization annotations that can be shown on any dashboard by configuring an annotation data source - they are filtered by tags. Or they can be tied to a panel on a dashboard and are then only shown on that panel.

> If you are running Grafana Enterprise, for some endpoints you'll need to have specific permissions. Refer to [Role-based access control permissions]({{< relref "/docs/grafana/latest/administration/roles-and-permissions/access-control/custom-role-actions-scopes" >}}) for more information.

## Find Annotations

`GET /api/annotations?from=1506676478816&to=1507281278816&tags=tag1&tags=tag2&limit=100`

**Required permissions**

See note in the [introduction]({{< ref "#annotations-api" >}}) for an explanation.

| Action           | Scope                   |
| ---------------- | ----------------------- |
| annotations:read | annotations:type:<type> |

**Example Request**:

```http
GET /api/annotations?from=1506676478816&to=1507281278816&tags=tag1&tags=tag2&limit=100 HTTP/1.1
Accept: application/json
Content-Type: application/json
Authorization: Basic YWRtaW46YWRtaW4=
```

Query Parameters:

- `from`: epoch datetime in milliseconds. Optional.
- `to`: epoch datetime in milliseconds. Optional.
- `limit`: number. Optional - default is 100. Max limit for results returned.
- `alertId`: number. Optional. Find annotations for a specified alert.
- `dashboardId`: number. Optional. Find annotations that are scoped to a specific dashboard
- `dashboardUID`: string. Optional. Find annotations that are scoped to a specific dashboard, when dashboardUID presents, dashboardId would be ignored.
- `panelId`: number. Optional. Find annotations that are scoped to a specific panel
- `userId`: number. Optional. Find annotations created by a specific user
- `type`: string. Optional. `alert`|`annotation` Return alerts or user created annotations
- `tags`: string. Optional. Use this to filter organization annotations. Organization annotations are annotations from an annotation data source that are not connected specifically to a dashboard or panel. To do an "AND" filtering with multiple tags, specify the tags parameter multiple times e.g. `tags=tag1&tags=tag2`.

**Example Response**:

```http
HTTP/1.1 200
Content-Type: application/json
[
```

> Starting in Grafana v6.4 regions annotations are now returned in one entity that now includes the timeEnd property.

## Create Annotation

Creates an annotation in the Grafana database. The `dashboardId` and `panelId` fields are optional.
If they are not specified then an organization annotation is created and can be queried in any dashboard that adds
the Grafana annotations data source. When creating a region annotation include the timeEnd property.

The format for `time` and `timeEnd` should be epoch numbers in millisecond resolution.

`POST /api/annotations`

**Required permissions**

See note in the [introduction]({{< ref "#annotations-api" >}}) for an explanation.

| Action             | Scope                   |
| ------------------ | ----------------------- |
| annotations:create | annotations:type:<type> |

**Required JSON Body Fields**

- `text`: description of the annotation.

**Example Request**:

```http
POST /api/annotations HTTP/1.1
Accept: application/json
Content-Type: application/json

```

**Example Response**:

```http
HTTP/1.1 200
Content-Type: application/json

```

> The response for this HTTP request is slightly different in versions prior to v6.4. In prior versions you would
> also get an endId if you where creating a region. But in 6.4 regions are represented using a single event with time and
> timeEnd properties.

## Create Annotation in Graphite format

Creates an annotation by using Graphite-compatible event format. The `when` and `data` fields are optional. If `when` is not specified then the current time will be used as annotation's timestamp. The `tags` field can also be in prior to Graphite `0.10.0`
format (string with multiple tags being separated by a space).
