n8n workflow automation with retries, logging, and review queues

PURPOSE

Designs and outputs n8n workflow JSON with robust triggers, idempotency, error handling, logging, retries, and human-in-the-loop review queues.

TRIGGERS:
- Build an n8n workflow that runs every Monday and emails the compliance summary.
- Add error handling and retries to this workflow, plus a review queue for failures.
- Create a webhook workflow that logs every run and writes a status row to a tracker.
- Make this n8n flow idempotent so it does not duplicate records when it reruns.
- Instrument this workflow with audit logs and a human approval step.
DO NOT USE WHEN…
- You need code-only automation without n8n (use a scripting/CI skill).
- You need to bypass security controls or hide audit trails.
- You need to purchase or recommend prohibited items/services.
