# Add contacts

> Save WhatsApp contacts to the phone's contact list

## Overview

This method is responsible for saving WhatsApp contacts to your phone's contact list.

<Warning>
  **About this feature**

  The method for adding contacts to the WhatsApp list will only work for accounts that have already received the necessary update. Make sure your **WhatsApp** account has received the update before using this feature. Otherwise, the operation will not be completed successfully.

  Additionally, you need to allow WhatsApp to add contacts directly on your phone. To do this, go to your app's privacy settings and adjust the permissions so that WhatsApp can access and modify your contacts.
