MongoDB Atlas sends alert notifications to Warrn via webhook. When an Atlas alert fires (OPEN status), Warrn creates an alert. When the Atlas alert is CLOSED, Warrn auto-resolves the matching alert.

​
Setup

1

Add the integration in Warrn

Open a service or team in Warrn. Go to the Integrations tab, add MongoDB Atlas,. Copy the generated webhook URL.
2

Configure the webhook in Atlas

In MongoDB Atlas, go to Project Settings > Integrations. Click Configure next to Webhook. Paste the webhook URL from Warrn and save.
3

Create alert rules

In Atlas, go to Alerts > Alert Settings. Configure the alert conditions you want routed to Warrn. The webhook integration applies to all alerts in the project.

​
How it works

Atlas sends a flat JSON payload per alert. The status field determines the action:
  • OPEN or INFORMATIONAL: Creates a new alert in Warrn. Deduplicates by Atlas alert id.
  • CLOSED: Auto-resolves the matching Warrn alert.
The alert name is extracted from the humanReadable field, which contains a multi-line summary. Warrn parses the first meaningful line (skipping metadata prefixes like “Project:”, “Organization:”, “Severity:”) and appends the cluster name.
