What do you mean, "Note: Appery.io facebook plugin could not to work in that cases"?

Is this information still current? Appery allows us to add custom parameters to notifications. How do we go about reading those custom parameters from the app?

Where do you place this code? What if the user is on another page that does not have this form load event when the push notification comes in?

Why is this question marked as answered when it is not answered? It's been a few years, and I would assume it be easy to configure a push notification to open a specific page in the app.
