idempotency_key_mode_conflict

Idempotency-Key used in the other mode

HTTP 409

This Idempotency-Key belongs to the other mode (live or test). Keys are per mode: the same key sent with a live key and a test key makes two records. But a key already held by a record of the other mode can't replay it, and a live key can't send a key that starts with test:, which names a test key's request. Nothing is written; send a new key.

The problem body

Sent as application/problem+json, with the request id in request_id and the X-Request-Id header. Branch on code: the error and detail sentences can change, and some operations add members of their own.
