# Legacy Alerting API

{{% admonition type="note" %}}
Starting with v9.0, the Legacy Alerting HTTP API is deprecated. It will be removed in a future release.
{{% /admonition %}}

This topic is relevant for the [legacy dashboard alerts](/docs/grafana/v8.5/alerting/old-alerting/) only.

If you are using Grafana Alerting, refer to [Alerting provisioning API]({{< relref "./alerting_provisioning" >}})

You can find Grafana Alerting API specification details [here](https://editor.swagger.io/?url=https://raw.githubusercontent.com/grafana/grafana/main/pkg/services/ngalert/api/tooling/post.json). Also, refer to [Grafana Alerting alerts documentation]({{< relref "../../alerting" >}}) for details on how to create and manage new alerts.

You can use the Alerting API to get information about legacy dashboard alerts and their states but this API cannot be used to modify the alert.
To create new alerts or modify them you need to update the dashboard JSON that contains the alerts.

## Get alerts

`GET /api/alerts/`

**Example Request**:

```http
GET /api/alerts HTTP/1.1
Accept: application/json
Content-Type: application/json
Authorization: Bearer eyJrIjoiT0tTcG1pUlY2RnVKZTFVaDFsNFZXdE9ZWmNrMkZYbk
```

Querystring Parameters:

These parameters are used as querystring parameters. For example:

`/api/alerts?dashboardId=1`

- **dashboardId** – Limit response to alerts in specified dashboard(s). You can specify multiple dashboards, e.g. dashboardId=23&dashboardId=35.
- **panelId** – Limit response to alert for a specified panel on a dashboard.
- **query** - Limit response to alerts having a name like this value.
- **state** - Return alerts with one or more of the following alert states: `ALL`,`no_data`, `paused`, `alerting`, `ok`, `pending`. To specify multiple states use the following format: `?state=paused&state=alerting`
- **limit** - Limit response to _X_ number of alerts.
- **folderId** – Limit response to alerts of dashboards in specified folder(s). You can specify multiple folders, e.g. folderId=23&folderId=35.
- **dashboardQuery** - Limit response to alerts having a dashboard name like this value.
- **dashboardTag** - Limit response to alerts of dashboards with specified tags. To do an "AND" filtering with multiple tags, specify the tags parameter multiple times e.g. dashboardTag=tag1&dashboardTag=tag2.

**Example Response**:

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

```

## Get alert by id

`GET /api/alerts/:id`

**Example Request**:

```http
GET /api/alerts/1 HTTP/1.1
Accept: application/json
Content-Type: application/json
Authorization: Bearer eyJrIjoiT0tTcG1pUlY2RnVKZTFVaDFsNFZXdE9ZWmNrMkZYbk
```

**Example Response**:

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

```

**Important Note**:
"evalMatches" data is cached in the db when and only when the state of the alert changes
(e.g. transitioning from "ok" to "alerting" state).

If data from one server triggers the alert first and, before that server is seen leaving alerting state,
a second server also enters a state that would trigger the alert, the second server will not be visible in "evalMatches" data.

## Pause alert by id

`POST /api/alerts/:id/pause`

**Example Request**:

```http
POST /api/alerts/1/pause HTTP/1.1
Accept: application/json
Content-Type: application/json
Authorization: Bearer eyJrIjoiT0tTcG1pUlY2RnVKZTFVaDFsNFZXdE9ZWmNrMkZYbk

```

The :id query parameter is the id of the alert to be paused or unpaused.

JSON Body Schema:

- **paused** – Can be `true` or `false`. True to pause an alert. False to unpause an alert.

**Example Response**:

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

```

## Pause all alerts

See [Admin API]({{< relref "/docs/grafana/latest/developers/http_api/admin#pause-all-alerts" >}}).
