Control-use an app with another app

I need an app (A) that can control another app (V). There is an app (V): [login to view URL] I want to create an app (A) that listens to see if an push notification happens to this V-app. If a push comes. Then I want A to "click" in a certain way in this V-app. I will give this info later exactly how to click. Speed is extremely important from the moment a push comes, it shouldn't take more that 100ms for this app to start "clicking". I wonder, is this possible? Price?
