## Fields

| Field | Type | Required | Notes |
| --- | --- | --- | --- |
| `entryId` | string (ID) | Yes | The ID of an accounting entry, from entries.list or attention.mine. |
| `taxMinor` | string | Yes | An amount in cents (the currency's smallest unit), written as a whole-number string such as "1250" for $12.50. Whole number written as a string. |
| `reason` | string | Yes | A short note saying why, kept in the record's history. 10–2000 characters. |
| `evidenceId` | string (ID) |  | The ID of the related record. |
| `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. |
