# Configure MQTT notifications

Use the MQTT integration in contact points to send alert notifications to your MQTT broker.

## Configure MQTT for a contact point

To create a contact point with MQTT integration, complete the following steps.

1. Navigate to **Alerts & IRM** -> **Alerting** -> **Notification configuration**, then select the **Contact points** tab.
1. Click **+ Add contact point**.
1. Enter a name for the contact point.
1. From the **Integration** list, select **MQTT**.
1. Enter your broker URL in the **Broker URL** field. Supports `tcp`, `ssl`, `mqtt`, `mqtts`, `ws`, `wss` schemes. For example: `tcp://127.0.0.1:1883`.
1. Enter the MQTT topic name in the **Topic** field.
1. (Optional) Configure [additional settings](#optional-settings).
1. Click **Save contact point**.

For more details on contact points, including how to test them and enable notifications, refer to [Configure contact points](ref:configure-contact-points).

{{< admonition type="note" >}}

When using the `json` **Message format**, only the **message** field of the JSON payload is customizable, and its output is formatted as a string.

To customize the full payload in text or JSON format, use the `text` format and define a [custom payload](#custom-payload).

{{< /admonition >}}

### Alert object

The Alert object represents an alert included in the notification group, as provided by the [`alerts` field](#body).

{{< docs/shared lookup="alerts/table-for-json-alert-object.md" source="grafana" version="<GRAFANA_VERSION>" >}}

## Custom payload

When you set the **Message format** option to `text`, you can customize the entire payload of the MQTT message.

In this mode, the **Message** option defines the entire payload. It supports [notification templates](ref:notification-templates) and can generate notification messages in plain text, JSON, or any custom format.

For examples of templates that produce plain text or JSON messages, refer to [notification template examples](ref:notification-template-examples).
