Notification / ack

[23tony]

I have an app where i need the receiving devices to acknowledge receipt of the notification. This is so the server can take certain actions after all of a user's registered devices have gotten it.

Currently I'm using a simple REST api http call, but I'm wondering if upstream notifications would be a better approach?

What would be the considerations for choosing one over the other?

Personally I'd be inclined to give FCM a try. It provides all the features you need - downstream/upstream message sending. All conveniently handled through nice APIs. There's a video here with a guy talking you through how to send bi-directional messages

He is using PHP on the server side (ugh!), but it's quick and dirty I suppose.
