Overview

The "React To Message" operation allows users to add or remove a reaction emoji on a specific message within a messaging platform. This node is useful for automating interactions such as acknowledging messages, expressing emotions, or managing message feedback programmatically. For example, it can be used in customer support workflows to automatically react with a thumbs-up emoji when a message is received, or to clear reactions when certain conditions are met.

Properties

Output

The node outputs JSON data representing the result of the reaction operation. This typically includes confirmation that the reaction was successfully added or removed on the specified message. There is no indication that binary data is output by this node.

Dependencies

• Requires an API key credential for authenticating with the WaAPI service.
• The node communicates with the WaAPI REST API endpoint at https://waapi.app/api/v1.
• Proper configuration of the API authentication credentials in n8n is necessary for successful execution.

Troubleshooting

• Common Issues:

  • Invalid or missing message ID may cause the operation to fail because the target message cannot be found.
  • Using an unsupported or invalid emoji character could result in errors or no visible reaction.
  • Missing or incorrect API credentials will prevent the node from authenticating with the external service.

• Error Messages:

  • Authentication errors usually indicate issues with the API key; verify and update credentials accordingly.
  • "Message not found" errors suggest the provided message ID does not exist or is inaccessible.
  • Validation errors related to the reaction property may occur if the emoji format is incorrect; ensure only a single emoji character or an empty string is used.
