# Download Document

> Download the binary content of a project document

```
GET /openapi/memorylake/api/v1/projects/{id}/documents/{documentId}/download
```

Downloads the binary content of a project document. The response is either a `303` redirect to the storage download URL, or streamed binary content.

<Note>
  **Permissions required (all of):**

  * [`project:doc_read`](/features/team-collaboration/permission-reference#read-a-single-document) · `instance`
  * [`drive:item_read`](/features/team-collaboration/permission-reference#read-your-files) · `service`

  The server resolves the document to its underlying Library file and forwards to the drive download handler — both permissions are checked on every call.
</Note>
