The PaymentRequestUpdateEvent interface is used for events sent to a PaymentRequest instance when changes are made to shipping-related information for a pending PaymentRequest. Those events are:

shippingaddresschange Secure context

Dispatched whenever the user changes their shipping address.

shippingoptionchange Secure context

Dispatched whenever the user changes a shipping option.

PaymentRequestUpdateEvent() Secure context

Creates a new PaymentRequestUpdateEvent object.

Provides only the properties inherited from its parent interface, Event.

In addition to methods inherited from the parent interface, Event, PaymentRequestUpdateEvent offers the following methods:

PaymentRequestUpdateEvent.updateWith() Secure context

If the event handler determines that information included in the payment request needs to be changed, or that new information needs to be added, it calls updateWith() with the information that needs to be replaced or added.
