It is possible to send passes via Apple Push Notifications directly? I know about the update function of passes via push. But I need to send the whole pass from a server after the user orders the ticket from an iPhone app.
I don't think you can, because the user should choose to add passes to their passbook, but why not show the pass in a PKAddPassesViewController while the user is still in the app? If the pass is issued well after the user's order is submitted, you could show a push notification saying the pass is ready, and to tap the push notification to show the pass.
