PaymentRequest event handler onmerchantvalidation is invoked when the merchantvalidation is fired, indicating that the payment handler (e.g., Apple Pay) requires the merchant to validate themselves. This is usually the first event to be fired, and the user won't be able to proceed with a payment until the merchant validate themselves.

This event is not be fired by all payment handlers. In particular, it's used by Apple Pay.

    const merchantServerUrl = window.location.origin +
        '/validation?url=' + encodeURIComponent(ev.validationURL);
    // get validation data, and complete validation;
    return await fetch(merchantServerUrl).then(r => r.text());
  })
};
const response = await request.show();
