Monitor alert
Get a push notification when a Datadog monitor triggers, warns, stops reporting data, or recovers, with priority following the monitor's P1–P5.
Three steps to your first push
STEP 01
Install the recipe
One click in Studio gives you a personal webhook URL.
STEP 02
Paste your URL into Datadog
Add it as a webhook for Monitor alert.
STEP 03
Get a push on your phone
With the text, sound and buttons from the recipe.
How to set up the Datadog monitor alert webhook
- Click Install in Studio and sign in. The recipe is added to your account and you get a personal webhook URL.
- In Datadog, open Integrations > Webhooks and add a new webhook named justpush.
- Paste your webhook URL as the URL and replace the payload with the one from the setup notes below.https://••••••••/•••••••• your personal URL, shown after install
- Add @webhook-justpush to the message of every monitor that should notify you.
- In **Integrations → Webhooks**, add a webhook named **justpush** with the URL above, and replace its payload with this:
- ```json
- {
- "source": "datadog",
- "title": "$EVENT_TITLE",
- "transition": "$ALERT_TRANSITION",
- "priority": "$ALERT_PRIORITY",
- "hostname": "$HOSTNAME",
- "link": "$LINK",
- "snapshot": "$SNAPSHOT",
- "org": "$ORG_NAME"
- }
- ```
- Then add **`@webhook-justpush`** to the message of each monitor that should notify you.
- The template leaves out `$EVENT_MSG` on purpose: a monitor message with quotes or line breaks could produce invalid JSON. Datadog doesn't sign webhook requests, so keep your endpoint URL private.
What runs when the webhook arrives
Studio calls handleRequest(request) with the incoming webhook and sends the message it returns. It's yours after install; change anything.

1// Datadog → monitor alert
2// Fires when a Datadog monitor that mentions @webhook-justpush triggers, warns,
3// has no data, or recovers. Uses the custom payload from INSTALL.md.
4// Docs: https://docs.datadoghq.com/integrations/webhooks/

6// $ALERT_TRANSITION values, how to label them, and the default priority.
7const TRANSITIONS = {

13 "No Data": { emoji: "⚪", priority: 0, suffix: " (no data)" },
14 Recovered: { emoji: "✅", priority: -1 },

17// $ALERT_PRIORITY → push priority for alerts (P1 pages you, P5 barely whispers).
18const PRIORITIES = { P1: 2, P2: 1, P3: 1, P4: 0, P5: -1 }

49 // already in the emoji, so keep just the monitor name and the scope.

The Datadog monitor webhook
This is what Datadog sends to your URL for monitor alert. It is a sample, trimmed to the fields recipes use.
