Is is possible for an application to handle the response from a push notification?

Question

Is it possible to get the user's response from a push notification and create a notification reply? i.e. if a user clicks the view button and views the app, can we take that action and let the sender of the notification know that the receiver has viewed / opened the app?

Answer 1

Short answer, Yes.

When the application starts due to a user electing to from a notification (local or remote) the application is started in a special way so that the application can process the notification. At this point it can do whatever you want, like send a message back to your service.

See Handling Local and Remote Notifications for details.
