# tags.notion.unlink

Stop syncing a project with Notion, with tagId and idempotencyKey. The project keeps its current name, dates, budget and description; nothing changes in Notion.

`POST /api/v1/accounting/tags.notion.unlink`

Permissions: `accounting:read`, `accounting:write` · Roles: admin, finance · Idempotency key required · Send `expectedRevision` · Reaches outside Oatmilk (email or a provider)

MCP tool: `accounting_tags_notion_unlink`

## Fields

| Field | Type | Required | Notes |
| --- | --- | --- | --- |
| `tagId` | string (ID) | Yes | The ID of a project tag, from tags.list. |
| `expectedRevision` | integer |  | 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. |
