Automation#Error Handling#HTTP#Resilience#Production
Resilient HTTP + Error Handler
Attach an Error Handler node to an HTTP call and Slack-notify your team the moment a request fails.
Resilient HTTP + Error Handler
Production workflows need fallback paths. The Error Handler node fires when any upstream node throws — here it catches HTTP failures and alerts your team before the error silently disappears.
What this workflow does
- Input provides the target URL (or replace with a Cron trigger)
- HTTP makes the request — if it succeeds, the happy path continues to Output
- Error Handler (attached to the HTTP node) intercepts any exception
- Slack sends an error alert with the failure reason
Use cases
- Monitoring critical API integrations
- Webhook delivery receipts with failure alerts
- Teaching defensive workflow design
Notes
Connect the Error Handler node to the HTTP node using the error handle. Attach Slack credentials in Heym — no secrets ship in the template.
