Use idempotency keys to avoid duplicate orders
Prevent duplicated orders or actions when n8n or another app retries the same request.
Why it matters
Automation tools may retry if internet or server response is slow. Without idempotency, the same external order could be submitted twice.
How to use it
- Create a unique key from the external system, such as website-order-1001.
- Send it as idempotency_key in JSON or X-BOS-Idempotency-Key in headers.
- If the same key is sent again, BOS returns the earlier response instead of creating a duplicate.
