# Get the list of users who can follow the file and mark the users who have followed the file

`GET /nd/api/file/user_can_focusfile`

## URL query parameters

| Parameter | Type | Description |
| --- | --- | --- |
| `file_id` | `string` | Required file ID |

## Response

The source does not provide a complete response schema.

Lists eligible followers and marks existing followers. The source PDF provides no response schema; confirm field names and marking behavior rather than assuming they match user_focusfile.

## Calling the Endpoint

Use `Authorization: Bearer <access_token>`. GET parameters belong in the URL query; normal business POST requests use JSON. Check HTTP status and then the business result. Confirm array serialization and ambiguous types with the deployment instead of inventing fields.
