# How to React to a Message

Acknowledge a message with an emoji reaction.

## React to a message

```
POST /reactions/message/{message_id}
```

Body:

```json
{ "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}
```
