Overview
The node provides an interface to interact with the Evolution API, specifically allowing users to react to messages within a chat. The "React to Message" operation lets you add an emoji reaction to a specific message in a chat instance. This is useful for automating responses or acknowledgments in messaging platforms that support reactions, such as confirming receipt of a message or expressing sentiment without sending a new message.
Practical examples include:
- Automatically reacting with a thumbs-up emoji when a task update message is received.
- Adding a custom emoji reaction to highlight important messages in group chats.
- Using reactions as quick feedback mechanisms in customer support chats.
Properties
| Name | Meaning |
|---|---|
| Instance Name | The name of the Evolution API instance to connect to. |
| Chat Number | The identifier (number) of the chat where the target message is located. |
| Message ID | The unique identifier of the message to which the reaction will be added. |
| Own Message | Boolean indicating whether the message is sent by yourself (true) or someone else (false). |
| Reaction Emoji | The emoji character to use as the reaction (e.g., 👍). |
Output
The node outputs a JSON array containing the result of the reaction operation. Typically, this includes confirmation details such as success status or metadata about the reacted message. The exact structure depends on the Evolution API response but generally confirms that the reaction was applied.
No binary data output is indicated.
Dependencies
- Requires an active connection to the Evolution API via an API key or authentication token configured in n8n credentials.
- Network access to
https://doc.evolution-api.com/api-referenceor the actual Evolution API endpoint. - Proper configuration of the node with valid instance name and chat/message identifiers.
Troubleshooting
- Unsupported operation error: If the node throws an error stating the operation is unsupported, verify that the resource is set to "messages-api" and the operation to "send-reaction".
- Invalid message or chat ID: Ensure the provided chat number and message ID are correct and exist in the specified instance.
- Authentication failures: Confirm that the API credentials are correctly set up and have permissions to send reactions.
- Emoji issues: Use standard Unicode emojis; some custom or unsupported emojis might cause errors.
- Network errors: Check connectivity to the Evolution API endpoint and firewall settings.
