Answer 1

Of course. You can send custom parameters as payload with apple push notification. Like Kevin Ballard said the payload will looks like the above. But remember one thing always you are dealing with push notification, As per the apple constraints the push notifications, The maximum size allowed for a notification payload is 256 bytes; Apple Push Notification Service refuses any notification that exceeds this. So please take this too in your consideration when you are going to add more data to notification.
