Service health monitoring with double-verification & Slack alerts

How it works

This workflow checks the health of your web services or APIs on a schedule, prevents false alerts with a second verification, and sends confirmed failure alerts directly to Slack.

• Performs scheduled HTTP health checks
• Waits and retries before confirming failure
• Sends alerts only if the service fails twice in a row
• Reduces false positives and avoids alert fatigue

Setup steps

1. Add your service URL(s) in the HTTP Request nodes
2. Configure your Slack Bot Token in n8n
3. Deploy the workflow
4. Get real-time Slack alerts when services go down 🚨

Use case

Perfect for IT teams, DevOps engineers, and developers who need reliable uptime monitoring without noise.
