Overview

The "Reagir Mensagem" (React to Message) operation of the "Mensagem" (Message) resource in this custom n8n node allows you to send a reaction (such as an emoji) to a specific message within a chat using the Evolution API. This is particularly useful for automating responses, acknowledging messages, or integrating with workflows that require feedback or interaction in messaging platforms.

Practical examples:

  • Automatically react with a thumbs-up emoji to confirm receipt of important notifications.
  • Use reactions to trigger further automation steps based on user interactions in a chat.
  • Provide visual feedback in group chats when certain keywords or events are detected.

Properties

Below are the supported input properties for this operation:

Display Name Type Meaning
Nome Da Instância String The name of the instance to use for sending the reaction.
Número Do Chat String The chat number where the target message is located.
ID Da Mensagem String The unique identifier of the message to which the reaction will be sent.
Mensagem Própria Boolean Indicates whether the message is your own message.
Emoji Da Reação String The emoji to use as the reaction (e.g., 👍).

Output

The output will be a JSON object (or array of objects) representing the result of the reaction operation. While the exact structure depends on the API response, it typically includes information such as:

{
  "status": "success",
  "messageId": "1234567890",
  "reaction": "👍"
}
  • status: Indicates if the reaction was successfully sent.
  • messageId: The ID of the message that received the reaction.
  • reaction: The emoji used as the reaction.

Note: The actual fields may vary depending on the Evolution API's response.

Dependencies

  • External Service: Requires access to the Evolution API.
  • API Key/Credentials: You must configure valid credentials for the "evolutionApi" in n8n.
  • n8n Configuration: Ensure the node is properly authenticated and has network access to https://doc.evolution-api.com/api-reference.

Troubleshooting

Common Issues:

  • Invalid Credentials: If the API key or credentials are incorrect, authentication errors will occur. Double-check your credential setup in n8n.
  • Unsupported Operation: If the selected operation or resource is not implemented, you may see an error like:
    • "Operação não suportada."
      Resolution: Ensure you have selected a valid combination of resource and operation.
  • Missing Required Fields: If any required property (such as "Nome Da Instância", "Número Do Chat", "ID Da Mensagem", or "Emoji Da Reação") is missing, the node will fail to execute. Fill in all mandatory fields.
