409 idempotency_key_reused

Idempotency key reused. You sent an Idempotency-Key again within 24 hours with a different body. The same key with the same body is never a conflict: it replays the first answer with Idempotent-Replayed: true, even while the first request is still running.

What to do

Use one key per logical attempt. Generate a new key when the body changes.

Note

Retrying the same request gives the same answer. Change the request first.
