Common Parameters (Description of WebInfo and Message Fields)

Note:
WebInfo and Message are both optional fields, but at least one must be provided.
If only WebInfo is included, the push notification is delivered exclusively via the browser notification bar.
If only Message is included, push notifications will be delivered to users only when the web page is open.
If both WebInfo and Message are included, online users receive the Message push notification, while offline users receive the WebInfo push notification in the browser notification bar.
