## 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. 8–160 characters. |
| `name` | string |  | A display name. 1–100 characters; Matches ^[^\u0000-\u001f\u007f]+$. |
| `scopes` | array of enum values |  | What the API key may do. A key can never do more than the person who made it. One of: `accounting:read`, `accounting:write`, `accounting:admin`, `mail:read`, `mail:write`, `mail:security`, `api_keys:manage`, `mailboxes:search`. 1–8 items. |
| `expiresAt` | string (date-time) |  | When this stops working, as an ISO 8601 date and time. |
