Overview

This node integrates with the Wassenger WhatsApp API to perform various operations related to WhatsApp messaging and management. Specifically, for the Chat Messages resource and the Get Message Details operation, it retrieves detailed information about a specific WhatsApp message by its unique message ID from a specified WhatsApp number (device). This is useful in scenarios where you need to fetch metadata or content details of a particular message, such as for auditing, customer support follow-up, or message tracking.

Practical examples include:

Fetching the full details of a customer’s WhatsApp message to display in a CRM.
Retrieving message status or content for compliance or record-keeping.
Debugging or verifying message delivery and content after sending.

Properties

Name	Meaning
WhatsApp Number	The identifier of the WhatsApp number (device) from which the message was sent or received. This is selected from available WhatsApp numbers linked to the account.
Message ID	The unique hexadecimal ID of the WhatsApp message whose details are to be retrieved.

Output

The output JSON contains detailed information about the requested WhatsApp message. This typically includes fields such as message content, sender and receiver info, timestamps, message status, and any metadata provided by the Wassenger API.

If the node supports binary data output (not explicitly shown here), it would represent media attachments or files associated with the message.

Dependencies

Requires an active Wassenger WhatsApp API key credential configured in n8n.
Depends on the Wassenger API service being accessible and the WhatsApp number (device) being valid and linked to the Wassenger account.
The node uses internal methods to load available WhatsApp numbers dynamically.

Troubleshooting

Common issues:
- Invalid or missing WhatsApp number/device ID: Ensure the device ID corresponds to a registered WhatsApp number in your Wassenger account.
- Incorrect or expired message ID: Verify that the message ID is correct and exists in the system.
- API authentication errors: Confirm that the API key credential is correctly set up and has necessary permissions.
- Network or connectivity problems: Check internet connection and Wassenger API availability.
Error messages:
- "error": "Message not found": The specified message ID does not exist for the given WhatsApp number.
- "error": "Unauthorized" or similar: Authentication failed; check API key validity.
- "error": "Device not found": The WhatsApp number/device ID is invalid or not linked.

Resolving these usually involves verifying input parameters, refreshing credentials, and ensuring the Wassenger service is operational.
