## Fields

| Field | Type | Required | Notes |
| --- | --- | --- | --- |
| `transactionId` | string (ID) | Yes | The ID of a bank or card transaction, from transactions.list. |
| `categoryId` | string (ID) |  | The ID of a category, from categories.list. |
| `type` | enum |  | One of: `expense`, `income`, `income_refund`, `refund`, `transfer`, `fee`. |
| `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. |
