UazAPI

Overview

The node integrates with the UazAPI service to automate WhatsApp messaging tasks. Specifically, the React to Message operation allows users to send an emoji reaction to a specific WhatsApp message. This is useful for quickly acknowledging messages without sending a full text reply, enhancing conversational flow and user engagement.

Common scenarios:

• Automatically reacting to customer inquiries or support messages with emojis like 👍 or ❤️.
• Adding quick feedback reactions in group chats or broadcast messages.
• Enhancing chatbot interactions by programmatically reacting to user messages.

Practical example:
You receive a message from a customer and want to acknowledge it with a thumbs-up emoji automatically. Using this node, you specify the recipient's number, the message ID, and the emoji to react with, and the node sends the reaction via WhatsApp.

Properties

Output

The node outputs a JSON object representing the response from the UazAPI after attempting to send the reaction. This typically includes status information about the reaction request, such as success confirmation or error details.

No binary data output is involved in this operation.

Example output structure (simplified):

{
  "success": true,
  "message": "Reaction sent",
  "data": {
    "number": "5511999999999",
    "messageId": "ABCD1234",
    "emoji": "👍"
  }
}

Dependencies

• Requires an active connection to the UazAPI service.
• Needs valid API credentials configured in n8n for authenticating requests to UazAPI.
• The base URL for the UazAPI must be set in the credentials.
• The node uses HTTP POST requests to the /message/react endpoint of the UazAPI.

Troubleshooting

• Common issues:

  • Invalid or missing phone number format: Ensure the number includes the country code and no "+" sign.
  • Incorrect or expired message ID: Verify that the message ID corresponds to a valid message accessible by the instance.
  • Authentication errors: Confirm that the API key credential is correctly configured and has necessary permissions.
  • Network or connectivity problems: Check internet access and UazAPI service availability.

• Error messages:

  • "Unauthorized" or "Authentication failed": Check API credentials.
  • "Message not found": Verify the message ID is correct and the message exists.
  • "Invalid number format": Correct the phone number format as per requirements.
  • "Failed to send reaction": Could indicate temporary service issues; retry or check logs.
