WEBHOOK RELIABILITY LAB / DEMO
Three deliveries. One intended order.
Retries are normal. Duplicate business actions are avoidable in a carefully designed integration. Replay a fictional order below to see the difference between a raw handler and a handler that remembers an event key.

Event deliveries: 0
No events delivered yet.
Demonstration only. No CRM or payment provider is contacted.
What a production test should include
- Replay the exact same event ID.
- Deliver two different event IDs for the same business order.
- Send simultaneous duplicates.
- Make the downstream API time out after accepting a write.
- Deliver events out of order and verify the final state.
This is a local simulation, not a production connector. Real protection requires durable storage, an atomic uniqueness rule and safe handling of downstream API timeouts. A stored event ID alone does not guarantee exactly-once delivery across two systems.

Getting duplicate orders in n8n?
Send an anonymised event example, the destination system and what is being duplicated. I will review whether one scoped repair is enough.
