## Fields

| `direction` | enum |  | One of: `push`, `pull`, `both`, `full`. Default `"both"`. |
| `idempotencyKey` | string | Yes | Any unique text you generate once per intended change, so a retried request only happens once. Send it as the Idempotency-Key header instead if you prefer; if you send both they must match. 8–200 characters. |
