Overview

This node operation "Send Text From Chatwoot" under the "Message" resource enables sending text messages via the MegaAPI WhatsApp service by extracting message data from a Chatwoot webhook payload. It is designed to automate WhatsApp messaging workflows triggered by Chatwoot events, such as when a new outgoing message is created in Chatwoot.

Typical use cases include:

  • Automatically forwarding Chatwoot outgoing messages to WhatsApp contacts.
  • Integrating Chatwoot conversations with WhatsApp messaging for seamless customer communication.
  • Automating responses or notifications on WhatsApp based on Chatwoot interactions.

For example, when a user sends a message in Chatwoot, this node can extract the recipient's phone number and message content from the Chatwoot event payload and send it as a WhatsApp message through MegaAPI.

Properties

Output

The node outputs JSON data representing the result of the send message operation. This typically includes confirmation details such as message ID, status, or any error information returned by the MegaAPI WhatsApp service.

No binary data output is indicated for this operation.

Dependencies

  • Requires integration with MegaAPI WhatsApp service to send messages.
  • Needs a valid API authentication token or credential configured in n8n to authorize requests to MegaAPI.
  • Expects input data in the form of a Chatwoot webhook payload (message_created event) containing message content and recipient information unless manual override is enabled.

Troubleshooting

  • Common Issues:

    • Missing or malformed Chatwoot payload: Ensure the input JSON matches the expected Chatwoot message_created event structure.
    • Incorrect recipient phone number format: Must follow WhatsApp JID format like 5511999999999@s.whatsapp.net.
    • API authentication errors: Verify that the MegaAPI credentials are correctly set up in n8n.
    • Network or connectivity issues with MegaAPI service.

  • Error Messages:

    • "Unknown message operation: sendText": Indicates the operation name is incorrect or unsupported; verify operation selection.
    • Errors related to missing required parameters like "To" or "Text" usually mean these fields were not provided or extracted properly.
    • API response errors will be included in the output JSON under an error field if the request fails.
