# Send PIX button

> Send a message with a PIX key and copy button

## Overview

With this method you can send PIX key messages with a copy button.

<Warning>
  Button sending is currently available, but there are some decisive factors for it to work. For more details check the [Button Status](/en/tips/button-status) topic.
</Warning>

<Info>
  PIX messages received on WhatsApp Web don't change the chat state — they don't mark as unread or move to the top of the list. Messages render normally. This is a WhatsApp Web bug.

#### Example on WhatsApp
