| HTTP status | 409 |

What happened
A second request arrived with an Idempotency-Key whose first request is still running. The response is HTTP 409.
What it means
The original request will complete and store its response; this one was not processed. Parallel retries with the same key are the usual cause.
What to do next
Wait briefly and retry with the same key. Once the first request finishes, the retry receives its stored response with Idempotency-Replayed: true.
