Overview
The node integrates with the UazAPI service to send WhatsApp messages and perform various WhatsApp-related operations. Specifically, for the Message - Send Text operation, it sends a plain text message to a specified phone number via WhatsApp.
This node is useful in scenarios such as:
- Automating customer notifications or alerts via WhatsApp.
- Sending personalized messages triggered by workflows (e.g., order confirmations, reminders).
- Integrating WhatsApp messaging into business processes without manual intervention.
Example use case: Automatically send a welcome message to new users who sign up on a website by triggering this node with their phone number and a custom greeting text.
Properties

Output
The node outputs a JSON object containing the response from the UazAPI after attempting to send the text message. This typically includes information about the success or failure of the message sending request, such as message ID, status, or error details if any.
No binary data output is produced by this operation.
Dependencies
- Requires an active connection to the UazAPI service.
- Needs valid credentials configured in n8n that provide:
- The base URL of the UazAPI instance.
- Authentication tokens required by UazAPI to authorize requests.
- The node uses HTTP requests authenticated via these credentials to communicate with UazAPI endpoints.
Troubleshooting
Common issues:
- Invalid or missing recipient number format (must include country code, no "+").
- Network connectivity problems preventing access to the UazAPI endpoint.
- Incorrect or expired API authentication tokens.
- UazAPI service errors or downtime.
Error messages:
- Errors returned from the UazAPI will appear in the node output under an
errorfield if "Continue On Fail" is enabled. - Typical errors might indicate invalid parameters, unauthorized access, or server errors.
- Errors returned from the UazAPI will appear in the node output under an
Resolutions:
- Verify the phone number format matches the expected pattern.
- Check and update API credentials in n8n.
- Ensure the UazAPI service is reachable and operational.
- Enable "Continue On Fail" to capture errors gracefully and debug.
