# trips.unlinkEntry

Take a transaction out of a trip with tripId, entryId and an idempotencyKey. Oatmilk never puts it back. Contributors can unlink only transactions they own.

MCP tool: `accounting_trips_unlink_entry`

## Fields

| Field | Type | Required | Notes |
| --- | --- | --- | --- |
| `tripId` | string (ID) | Yes | The ID of the related record. |
| `entryId` | string (ID) | Yes | The ID of an accounting entry, from entries.list or attention.mine. |
| `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. |
