# Reaction

Reaction messages are emoji-reactions that you can apply to a previous WhatsApp user message that you have received.

### Limitations

When sending a reaction message, only a sent message webhook (`status` set to `sent`) will be triggered; delivered and read message webhooks will not be triggered.

### Reaction Message Request

<mark style="color:orange;">`POST`</mark> `https://waba-v2.360dialog.io/messages`

Use the messages endpoint to send a reaction message to a WhatsApp user.
