## Fields

| Field | Type | Required | Notes |
| --- | --- | --- | --- |
| `selections` | array of objects | Yes | 1–100 items. |
| `selections[].pageId` | string | Yes | 32–36 characters. |
| `selections[].invoiceId` | string (ID) | Yes | The ID of the related record. |
| `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. |
