## Fields

| Field | Type | Required | Notes |
| --- | --- | --- | --- |
| `id` | string (ID) | Yes | The record's ID. |
| `expectedRevision` | integer | Yes | 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. at most 9007199254740991; greater than 0. |
| `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. |
| `url` | string |  | A full web address, starting with https://. 10–2000 characters. |
| `description` | string |  | A short description. at most 500 characters. |
| `events` | array of strings |  | Event types to receive: exact names such as invoice.paid, a group wildcard such as invoice.*, or * for everything. 1–100 items; each 1–80 characters. |
| `active` | boolean |  | Whether the record is turned on. |
