Address Book API provides an interface to work with phone address book, upload it to server and retrieve already registered ConnectyCube users from your address book.
With conjunction of User authentication via phone number you can easily organize a modern state of the art logic in your App where you can easily start chatting with your phone contacts, without adding them manually as friends - the same what you can see in WhatsApp, Telegram, Facebook Messenger and Viber.

You also can upload more contacts, not just all in one request - they will be added to your address book on the backend. If you want to override the whole address book on the backend - just provide boolean force = true
You also can remove a contact by setting contact.setIsDestroy(true);
