Overview
This node integrates with the Go WhatsApp Web MultiDevice API, enabling users to interact programmatically with WhatsApp messaging features. Specifically, the "React to Message" operation under the "Message" resource allows adding an emoji reaction to a specific WhatsApp message in either a private chat or group chat.
Common scenarios for this node include:
- Automatically reacting to incoming messages based on certain triggers or conditions.
- Enhancing chatbot interactions by providing emoji feedback.
- Managing message reactions in bulk or as part of workflow automations.
For example, a user could set up a workflow that reacts with a thumbs-up emoji ("👍") whenever a customer sends a positive feedback message.
Properties
| Name | Meaning |
|---|---|
| Phone Number or Group ID | The phone number (for private chats) or the Group ID (for group chats) where the message is located. |
| Message ID | The unique identifier of the message to which the emoji reaction will be added. |
| Emoji | The emoji character to use as the reaction. Defaults to "👍". |
Output
The node outputs JSON data representing the result of the reaction operation. This typically includes confirmation details such as success status or updated message metadata reflecting the added reaction.
No binary data output is involved in this operation.
Dependencies
- Requires an active connection to the Go WhatsApp Web MultiDevice API.
- Needs an API authentication credential configured in n8n to authorize requests.

Troubleshooting
Common issues:
- Invalid or missing phone number/group ID or message ID can cause failures.
- Using an unsupported or invalid emoji may result in errors.
- Network or authentication problems with the Go WhatsApp API can prevent successful reactions.
Error messages and resolutions:
- "Unknown resource" — indicates an incorrect resource parameter; ensure "message" is selected.
- API authentication errors — verify that the API key or token is correctly configured in credentials.
- Message not found — confirm the message ID exists in the specified chat or group.
