Overview
This node enables interaction with WhatsApp via the Wappfy API, specifically allowing users to send reactions (emoji responses) to existing WhatsApp messages. It is useful in scenarios where you want to automate or programmatically add emoji reactions to messages within WhatsApp chats, such as acknowledging receipt, expressing emotions, or providing quick feedback without sending a full text reply.
For example, you can use this node to automatically react with a thumbs-up emoji 👍 to a message confirming an order or to mark a message as seen with a reaction emoji in customer support workflows.
Properties
| Name | Meaning |
|---|---|
| Message ID | The unique identifier of the WhatsApp message to which you want to send a reaction. This specifies the target message. |
| Reaction Emoji | The emoji character used to react to the message. For example, 👍 for thumbs up, ❤️ for heart, etc. |
Output
The node outputs the JSON response returned by the Wappfy API after sending the reaction. This typically includes confirmation details about the reaction sent or any relevant metadata from the API. The output is structured as a JSON object under the json field.
No binary data output is produced by this operation.
Dependencies
- Requires a valid Wappfy API credential configured in n8n, including:
- Base URL of the Wappfy API.
- Instance name identifying the WhatsApp session.
- An API key for authentication.
- The node makes HTTP POST requests to the Wappfy API endpoint
/api/sendReaction.
Troubleshooting
Common issues:
- Invalid or missing Message ID: Ensure the message ID corresponds to an existing message in the WhatsApp session.
- Incorrect or unsupported emoji format: Use standard Unicode emoji characters.
- Authentication errors: Verify that the API key and instance name are correctly set in credentials.
- Network or API endpoint errors: Check connectivity to the Wappfy API base URL.
Error messages:
- Errors from the API will be returned in the node's output JSON under an error property if "Continue on Fail" is enabled.
- If not continuing on fail, the node throws an error with the API message.
To resolve errors, verify input parameters, credentials, and network access.
