# Import Rules From File Handler

`POST /api/rules/import/file`

Import a rule from an arbitrary file on the backend host.

The file's full contents become the rule body. Reading an arbitrary
path is only safe on a single-user local backend, so it is refused in
multi-tenant cloud mode where the filesystem is shared across clients.

## Request body

- ImportFileRequest
  - `path` string, required
  - `name` string, nullable

## Response `200`
