Overview

This node integrates with the Wassenger WhatsApp API to manage outbound files related to WhatsApp messaging. Specifically, the "Download File" operation under the "Files" resource allows users to download a file by specifying its unique file ID. This is useful in scenarios where you need to retrieve media or documents previously sent or received via WhatsApp through the Wassenger platform.

Practical examples include:

Downloading an image or document sent to a customer for archival or processing.
Retrieving audio or video files shared in WhatsApp conversations for further analysis.
Automating backup of outbound files from WhatsApp channels.

Properties

Name	Meaning
File ID	The unique identifier of the file to download. This ID is used to fetch the specific file.

Output

The node outputs JSON data representing the downloaded file's content or metadata as returned by the Wassenger API. If the file is binary (e.g., image, audio, video), the node will provide the file data accordingly, typically in a binary format suitable for further processing or saving.

Dependencies

Requires an API key credential for authenticating with the Wassenger WhatsApp API.
The node depends on the Wassenger service being accessible and the API key having permissions to access outbound files.
No additional environment variables are explicitly required beyond the API key credential configuration.

Troubleshooting

Common issues:
- Invalid or expired file ID: The node may fail if the provided file ID does not exist or has been deleted.
- Authentication errors: If the API key is missing, invalid, or lacks proper permissions, the node will throw authentication errors.
- Network or API downtime: Connectivity issues with the Wassenger API can cause request failures.
Error messages and resolutions:
- "File not found": Verify that the File ID is correct and that the file still exists in the Wassenger system.
- "Authentication failed": Check that the API key credential is correctly configured and valid.
- "Request timeout" or similar network errors: Ensure stable internet connection and that the Wassenger API endpoint is reachable.
