## Fields

| Field | Type | Required | Notes |
| --- | --- | --- | --- |
| `id` | string (ID) |  | The record's ID. |
| `expectedRevision` | integer |  | The record's current revision, from the last time you read it. If someone changed the record since, the request is refused with a conflict so you can reload and check before trying again. 0 to 9007199254740991. |
| `title` | string | Yes | A short title. 1–120 characters. |
| `content` | string | Yes | 1–2000 characters. |
| `active` | boolean |  | Whether the record is turned on. Default `true`. |
| `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. |
