shippingOptionChanged callback function to the
callbacks property of the
SqPaymentForm initializing argument. The callback is invoked when a shipping option is changed on the payment sheet. Use the callback to calculate a new shipping cost and other fees. If the calculation results in a line item amount change, update the payment request with the new amounts by calling the
done function in the callback.
For an Apple Pay payment request, avoid a timeout by calling
done within 30 seconds to respond to the shipping option change. Pass in an optional PaymentDetailsUpdate
object to update the payment total or line items.
Google Pay does not timeout the shipping option changed callback.
