Pass updates are an important way to engage with your users after the pass is created. For example,
by updating the event ticket points on a users card as they redeem their points.
To update the way passes are displayed, such as when the logo changes, you only need to update or
patch the event ticket class or use the Google Pay and Wallet Console.
Google propagates this information to every event ticket object associated to the updated
event ticket class.
This is the case for all fields defined at the event ticket class level.
To update a single pass, such as when the event ticket points balance changes,
you need to update or patch a single event ticket object. This is the case for all fields defined at the
event ticket object level.
