Creating real-time popup alerts using HTTP requests

I'd like to be able to trigger popups from remote servers in response to events.  For example, an emergency notice should be able to overlay the default content for a defined period, including audio message.  This would of course use the same authentication, e.g. OAuth token/JWT.  Ideally, the system should be able to accept popups from multiple sources, each of which will overlay the previous one, or optionally tile, or even join a scrolling queue. 

The advantage of this is obvious -- emergency real-time communication in a crisis situation.

We do support alerts using Common Alert Protocol version 1.2 (services like E2Campus or Rave).

Sadly, that just doesn't seem to work -- and you removed documentation from your web site covering that.  We don't want to pay for services like E2Campus or Rave -- we just want basic popups.

At this time we only support alerts via the Common Alert Protocol and that service is functioning as designed right now. As of right now we don't support pop-ups via any other messaging format, but, this doesn't eliminate anyone from creating this. If you have content that you create that is an HTML page you can setup whatever service you like using socks.js,, etc. to maintain a connection with that page and direct it to show whatever you would like when an alert / pop up situation occurs. You can schedule and deliver that page to Displays and once there that real time connection should work just fine. But, this will require development on your part, which I completely understand may not be an option. Thanks
