Push notification
A push notification is a message initiated by a service that can alert someone to new information on their device. Updated card contents alone do not amount to a visible notification.

What this means for your shop
In everyday use, push usually means an alert a customer notices on their phone without first opening your card. That differs from technical communication in the background. A signal to update the pass does not have to become a visible message.
Apple’s archived developer documentation distinguishes fetching a changed pass from showing a change message. Google also documents notifications separately. Which of these options a particular provider uses is up to that provider.
How to recognise it
A message about new opening hours appears in the card details and is seen when someone opens them. The content has arrived, even if no alert appeared outside the card. Plan urgent news with that in mind: not every customer sees a message straight away.
At Treubar
Campaigns are available from Pro. In Google Wallet, Treubar campaign messages currently appear in the card details without a notification banner. Apple Wallet can show an alert, depending on the connection, settings and delivery. Repeating identical message text may produce no new alert, so give each campaign its own wording.
Write the message so its purpose is clear even when someone opens it later. The push feature page explains the product’s scope; the Apple Wallet guide distinguishes card balances from notifications.
