idempotency_key_in_progress

HTTP status: 409 Conflict

Another request with the same Idempotency-Key is still being processed.

Common causes

• A client retried a create before the original completed.
• Two concurrent requests reused the same idempotency key.

How to fix

Wait for the original request to finish, then retry. Use a unique key per logical create. See Conventions → Idempotency.
