    Optional idempotency key. If a bulk request with this key already exists for your
    environment, the existing request is returned instead of creating a new one. Several
    mutating operations are additionally idempotent by design (e.g. cancel/retry a bulk
    request re-applies cleanly; create-or-update balance is an upsert).
