Template fields now support change messages, so an update can announce itself on the lock screen instead of changing silently.
Silent updates keep a pass current. Sometimes, though, you want the holder to notice: the gate moved, the balance changed, their order is ready.

whenever that field's value changes.
PATCH that changes the field's value triggers the notificationOne string turns a data sync into a customer touchpoint.
