Overview
This node allows you to download a file linked via a specific file link ID. It is useful in scenarios where you need to programmatically retrieve files stored or referenced by an external system using their unique file link identifiers. For example, automating the download of project documents or attachments referenced by file links in a project management or document storage system.
Properties
| Name | Meaning |
|---|---|
| Id | The unique identifier of the file link to download. This is a required numeric value representing the file link's ID. |
Output
The node outputs the downloaded file data. The output includes a json field containing metadata about the file link and the file itself. Additionally, if the file is binary (e.g., images, PDFs), the node outputs the file content in a binary format suitable for further processing or saving.
Dependencies
- Requires an API key credential to authenticate with the external service hosting the file links.
- The node depends on the base URL and authentication credentials configured in n8n to access the file link API endpoint.
Troubleshooting
- Invalid or missing file link ID: Ensure the "Id" property is set correctly and corresponds to an existing file link.
- Authentication errors: Verify that the API key or authentication token is valid and has sufficient permissions to access file links.
- Network issues: Check connectivity to the external service URL.
- File not found or deleted: The file link ID might reference a file that no longer exists or is inaccessible.
Links and References
- Refer to the external service’s API documentation for details on file link management and download endpoints.
- Consult n8n documentation on how to configure API credentials and handle binary data outputs.
