Overview

This node integrates with the Wassenger WhatsApp API to perform various operations related to WhatsApp messaging and management. Specifically, for the Chat Files resource with the Download File operation, it allows users to download files that have been shared in WhatsApp chats associated with a particular WhatsApp number.

Typical use cases include:

Automatically retrieving media files (images, videos, documents) sent or received via WhatsApp for archiving or processing.
Integrating WhatsApp file downloads into workflows such as CRM updates, content moderation, or backup systems.
Enabling automated handling of chat attachments without manual intervention.

For example, a user can configure this node to download a specific file by providing the WhatsApp number and the file ID, then save or process the downloaded file further in their workflow.

Properties

Name	Meaning
WhatsApp Number	The ID of the WhatsApp number (device) from which to download the file. This identifies the WhatsApp account involved. Options are dynamically loaded from available devices.
File ID	The ID of the file to download from the specified WhatsApp number. Options are dynamically loaded based on available files for the device.

Output

The node outputs JSON data representing the result of the file download operation. Typically, this includes metadata about the downloaded file and possibly the file content itself.

If the node supports binary data output (common for file downloads), the binary data will represent the actual file content retrieved from WhatsApp. This enables subsequent nodes to handle the file directly, such as saving it to disk, uploading it elsewhere, or processing it further.

Dependencies

Requires an active connection to the Wassenger WhatsApp API.
Needs an API key credential configured in n8n to authenticate requests.
The node depends on dynamic loading methods to fetch available WhatsApp numbers (devices) and files, so proper API access and permissions are necessary.

Troubleshooting

Common issues:
- Invalid or expired API key leading to authentication errors.
- Specifying a WhatsApp number or file ID that does not exist or is inaccessible.
- Network connectivity problems preventing communication with the Wassenger API.
Error messages:
- Authentication failures usually indicate incorrect or missing API credentials; verify and update the API key.
- "File not found" errors suggest the provided file ID is invalid or the file has been deleted; confirm the file ID is correct.
- Rate limiting or quota exceeded errors may occur if too many requests are made; consider adding delays or upgrading API plan.
