**Python**


```python
from tasksmate import TasksMate

tm = TasksMate()  # reads TASKSMATE_TOKEN
result = tm.milestones.update("<team_id>", "<milestone_id>", {"title": "string", "status": "string"})
print(result)
```

Response 200

```json
{
  "milestone_id": "string",
  "org_id": "string",
  "team_id": "string",
  "title": "string",
  "target_date": "2026-09-25",
  "description": "string",
  "owner_user_id": "string",
  "status": "open",
  "closed_at": "2026-09-25T12:00:00Z",
  "closed_by": "string",
  "created_by": "string",
  "updated_by": "string",
  "created_at": "2026-09-25T12:00:00Z",
  "updated_at": "2026-09-25T12:00:00Z",
  "is_active": true,
  "stop_id": "string",
  "task_count": 0,
  "completed_count": 0
}
```

A true partial. `{status: 'closed'}` closes (writes `closed_at` / `closed_by`), `{status: 'open'}` re-opens (clears them). The milestone’s owner may send `status` alone.

_Milestone Id_

string

**team\_id**

_Team Id_

string

## Request Bodyrequired

application/json

_MilestoneUpdate_

A partial update: fields you leave out are unchanged.

-   `description` / `owner_user_id` sent as null clear them.
-   `status` closes or re-opens the milestone: closing records `closed_at` / `closed_by`, re-opening clears them.
-   The milestone’s owner without team `edit` rights may send `status` only — anything else is a 403.
