# Draft head + who moved it

`GET /dashboards/{dashboard_id}/head`

## Request

- Base URL: `https://app.mammoth.io/api/v2`
- URL: `https://app.mammoth.io/api/v2/dashboards/{dashboard_id}/head`
- Auth: one of:
  - HTTP bearer
  - API key in header `X-API-KEY` and API key in header `X-API-SECRET` and API key in header `X-WORKSPACE-ID`

The draft head's sequence and the versions written since `since` (who, when, and the timeline's label for each, newest first). The editor polls this so a colleague's change is announced before its own next save runs into the base_sequence guard. Reads no canvas. Without `since` it describes the head version alone. `limit` (1-50, default 10) caps the listed moves; `count` is the total.

## Path parameters

- `dashboard_id` integer, required

## Query parameters

- `since` integer, nullable
- `limit` integer

## Response `200`

The draft head and the attributed versions since `since`

    - `sequence` integer, required: The version this write produced
    - `user_id` integer, nullable: Who wrote it
    - `user_name` string: Their display name

    - `kind` 'edit' | 'assistant' | 'sync', required: A manual/server edit, an assistant turn, or a data sync
    - `label` string, nullable: The timeline's own words for the change, if any
