n8n workflow pre-production checklist

Before moving an n8n workflow into production, run this quick checklist.

1) Trigger safety

Confirm each trigger has clear boundaries: source, expected payload shape, and duplicate handling.

2) Error handling

Critical branches should define fallback behavior. Silent failures are usually worse than explicit stops.

3) Credential hygiene

No secrets in static fields or plain text notes. Keep credentials in n8n credential storage and environment variables.

4) Cost controls

Place filters before expensive integrations. Avoid running AI or paid API calls on broad, unqualified inputs.

5) Idempotency

If a step retries, can it run twice safely? If not, add safeguards before deployment.

6) Observability

Add enough logging and metadata to understand why a run failed without replaying everything manually.

A short checklist catches issues early and reduces rollback pressure later.
