I try sending push notification, I'm on server-side. Is there a way in WNS, the push service for Windows 8, to send additional parameters, that will not be displayed. On Windows Phone 7, I use the wp:Param as Follow :
<?xml version="1.0" encoding="utf-8"?>
<wp:Notification xmlns:wp="WPNotification">
<wp:Toast>
.....
<wp:Param></wp:Param>
</wp:Toast>
</wp:Notification>
Is there an equivalent for toast for exemple ?
