WassengerInstall

Overview

The "Get File" operation under the "Files" resource in this node allows users to retrieve a specific outbound file by its unique identifier. This is useful when you need to access or download files that have been previously sent or managed through the Wassenger WhatsApp API integration.

Common scenarios include:

• Downloading media files (images, documents, videos) that were sent out via WhatsApp.
• Previewing or processing files linked to outbound messages for auditing or record-keeping.
• Integrating with other systems where file retrieval from WhatsApp conversations is necessary.

For example, a user might want to fetch a PDF invoice sent to a customer or retrieve an image shared during a support chat.

Properties

Output

The node outputs JSON data representing the details and content of the requested file. The exact structure depends on the API response but typically includes metadata about the file such as its name, type, size, and possibly a URL or binary data reference for downloading or previewing the file.

If the node supports binary output (not explicitly shown here), it would provide the actual file content in binary form, enabling direct file downloads or further processing within n8n workflows.

Dependencies

• Requires an active connection to the Wassenger WhatsApp API using a valid API key credential.
• The node depends on the external Wassenger service to fetch outbound files.
• Proper configuration of the API key credential in n8n is necessary for authentication.

Troubleshooting

• File Not Found: If the provided File ID does not exist or is incorrect, the node may throw an error indicating the file could not be found. Verify the File ID is correct and corresponds to an existing outbound file.
• Authentication Errors: Missing or invalid API credentials will cause authentication failures. Ensure the API key credential is correctly set up and has sufficient permissions.
• Network Issues: Connectivity problems with the Wassenger API endpoint can result in timeouts or failed requests. Check network settings and API availability.
• Permission Denied: If the API key lacks rights to access outbound files, permission errors may occur. Confirm the API key's scope includes file retrieval.

When errors occur, if the node is configured to continue on failure, it will output an error message in the JSON field instead of stopping the workflow.
