idempotency_key_in_progress

HTTP status: 409 Conflict. Retrying the same request can succeed.

Why it happens

• A retry arrived while the first attempt was still running, for example after a client timeout.

What to do

Wait for the number of seconds in the Retry-After header, then retry with the same key. You'll get the first request's result.

Example

The response is application/problem+json. Branch on code, never on title or detail. See errors for the format.
