Header Parameters

Idempotency-Key?string

Opaque client-generated key (1-255 chars) that makes a write safe to retry for 24h. A replay of the same key and body returns the original response with Idempotent-Replayed: true. Reusing the key with a different body returns 422 idempotency_key_reuse; an in-flight duplicate returns 409 request_in_flight.
