How to React to a Message

Acknowledge a message with an emoji reaction.

React to a message

POST /reactions/message/{message_id}

Body:

{ "reaction": "❤️" }

• message_id — the id from the webhook payload (or the id field of the send response).
• reaction — any unicode emoji (e.g. ❤️, ✅, 👍, 🎉), or a curated reaction id. The server normalizes both to the stored emoji.

Remove a reaction

Send the same body to:

DELETE /reactions/message/{message_id}
