## Inbound Reactions

When a lead reacts to a message:

* The reaction is detected and stored (not shown as a text message)
* No AI call is triggered — reactions are not treated as replies
* No notification is sent to the contact owner
* Tuco can also emit a `message.reaction` webhook for integrations that want to track reactions in real time

## Outbound Reactions

React to lead messages from the Unibox — hover over a message to see the reaction picker.

You can also send reactions through the API using `POST /api/messages/react`.
See the [Send Reaction API reference](/api-reference/endpoint/send-reaction).

If you want to sync inbound reactions into your CRM or automation layer, see [Message Webhooks](/api-reference/message-webhooks).

## How Reactions Appear

Reactions are displayed as emoji overlays on the original message bubble in Unibox, matching the native iMessage experience.
