How to connect Datadog

Step 1: Create an Integration

Go to your organization’s Integrations page.
Click Add Integration and select Datadog.
You’ll receive a unique Webhook URL. Copy it.

Step 2: Add the Webhook in Datadog

In Datadog, open the Webhooks integration tile and add a new webhook.
Name it hookfire and paste your Hookfire webhook URL.
Paste this into Payload:

{
  "transition": "$ALERT_TRANSITION",
  "alert_type": "$ALERT_TYPE",
  "alert_title": "$ALERT_TITLE",
  "event_title": "$EVENT_TITLE",
  "body": "$TEXT_ONLY_MSG",
  "link": "$LINK",
  "monitor_id": "$ALERT_ID",
  "hostname": "$HOSTNAME",
  "priority": "$ALERT_PRIORITY",
  "scope": "$ALERT_SCOPE",
  "date": "$DATE_POSIX",
  "org": "$ORG_NAME"
}

Add the custom header from Step 3, leave Encode as form off and save.
In each monitor you want on your phone, add @webhook-hookfire to the notification message.

Step 3: Signing Secret (custom header)

Datadog does not sign webhooks, so Hookfire checks a secret header instead:

Make up a long random string.
In the tile, create a custom variable HOOKFIRE_SECRET with that string as the value and tick hide from view.
Set the webhook’s Custom Headers to {"X-Hookfire-Secret": "$HOOKFIRE_SECRET"}.
Paste the same string into the Signing Secret field on your Hookfire integration page.

Step 4: Subscribe to Events

On your Hookfire integration page, toggle on the transitions you want to receive push notifications for. Most people take Triggered and Recovered, and mark Triggered high priority.

Step 5: Test

Click the Test button next to an event on your integration page, or use Test Notifications on a monitor that mentions @webhook-hookfire.

Supported Events

Event	Description
`Triggered`	A monitor went into alert
`Re-Triggered`	A monitor is still alerting after renotifying
`Warn`	A monitor passed its warning threshold
`Re-Warn`	A monitor is still warning after renotifying
`No Data`	A monitor stopped receiving data
`Re-No Data`	A monitor still has no data after renotifying
`Recovered`	A monitor recovered
`Renotify`	A reminder for a monitor that is still alerting

The event is Datadog’s $ALERT_TRANSITION, which is why the payload above sends it as transition.
