How to send push notifications to one particular user?
The app will automatically append ?player_id=XXXXX to your website URL. If your website URL is https://www.example.org, Convertify will call https://www.example.org/?player_id=XXXXX instead. Only your FIRST URL request will get that GET variable, so save it in a session or in a cookie to access it on your linked pages.
This code "XXXXX" that you saved is called player id in OneSignal. To send push notifications to a single user follow this tutorial
