Passbook / Wallet: How are notification warnings working

I am currently investigating the features of wallt/passbook and there is one thing I am struggling with: "Notifications".

Is there any way to push messages to the lock screen in real time using passbook? If I check several passes that I have installed (clicking the info icon), it suggests to turn on live updates & notifications.

Live updates is updating the pass itself is one feature that explains itself.

But what about the notifications? Is this working for passbook without having an app in addition? Is it a real push message that looks as if it is coming from an app? I really tried RTFM but did not find a lot.

Yes - you get a real push message, just like with an app.

Maybe you missed this part of the manual Updating a Pass - the section Devices Display Change Messages is describing lock screen messages.

The device compares the latest version of the pass against the version it had before to determine which fields have changed. If the value of a field has changed and the field specifies a change message, the device shows the message to inform the user about the change.

So, by pushing an update to a pass, you will trigger a lock screen message for any field that has changed its value and has a changeMessage set in pass.json.

The only difference between this and an App message, is that you can only set the text of the message (via the changeMessage entry for the value in question). Other rich push message functions like custom alerts and actions are not available.
