PaymentRequestEvent.changePaymentMethod()

Enables payment handlers to get the updated total from the merchant in response to a change in payment instrument selected within the payment handler. This fires the PaymentMethodChangeEvent on the merchant website.

For example, if the user selects a debit card with a billing address in France, the merchant may need to add value added tax to the total.
