# Reaction messages

# Reaction messages

Updated: Nov 3, 2025

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](https://developers.facebook.com/documentation/business-messaging/whatsapp/webhooks/reference/messages/status) (`status` set to `sent`) will be triggered; delivered and read message webhooks will not be triggered.

## Request syntax

Use the [POST /\<WHATSAPP\_BUSINESS\_PHONE\_NUMBER\_ID>/messages](https://developers.facebook.com/documentation/business-messaging/whatsapp/reference/whatsapp-business-phone-number/message-api) endpoint to apply an emoji reaction on a message you have received from a WhatsApp user.

```
curl 'https://graph.facebook.com/&lt;API_VERSION&gt;/&lt;WHATSAPP_BUSINESS_PHONE_NUMBER_ID&gt;/messages' \
-H 'Content-Type: application/json' \
-H 'Authorization: Bearer &lt;ACCESS_TOKEN&gt;' \
-d '

  "reaction": {
    "message_id": "&lt;WHATSAPP_MESSAGE_ID&gt;",
    "emoji": "&lt;EMOJI&gt;"
  }
}'
```
