## Fields

| Field | Type | Required | Notes |

| `kind` | enum | Yes | Which kind of record or job this is. One of: `block`, `footer`. |

| `body` | string | Yes | 1–20000 characters. |
| `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. |
