title: Apple Pay: How can I get `shippingAddress` before show the order information?
body: <p>I'm using Apple Pay integration with Stripe and I need to get the <code>shippingAddress</code> from Apple Pay before shown the order information because I need to calculate taxes and shipment cost based on the address.</p>
  
  <p>Currently, I can get the shipmentAddress but after show the window with the information.</p>
  
  <p>I'm sending this payload:</p>
  
  <pre><code>    var paymentRequest = {
        requiredShippingContactFields: ['postalAddress','email', 'phone'],
        countryCode: 'US',
        currencyCode: 'USD',
        lineItems: this.buildLineItems(lineItems),
        total: this.buildTotal(lineItems)
      };
  </code></pre>
  
  <p>There's a way to get the shipment information before show the window or update the window based on the information that I get?</p>
