title: Magento 1.6 FedEx No Quotes
body: <p>As you might know, there's FedEx Web Services API in Magento. But I still can't make it work.
  Entered all (password, account id, key and so on) in the admin end of the Magento.
  Still getting </p>
  
  <blockquote>
    <p>This shipping method is currently unavailable. If you would like to ship using this shipping method, please contact us.</p>
  </blockquote>
  
  <p>Tried to catch what's happening in <strong>code/core/Mage/Usa/Model/Shipping/Carrier/Fedex.php</strong>
  Right when the SOAP request is sent, <strong>line ~360</strong>:</p>
  
  <pre><code>    $requestString = serialize($ratesRequest);
      $response = $this-&gt;_getCachedQuotes($requestString);
  </code></pre>
  
  <p>Caught <code>$requestString</code> and <code>$response</code>.
  <code>$response</code> is always empty (print_r gives empty string), also tried to set "Sandbox mode" both Yes and No in the admin-end.
  The <code>$requestString</code> is:</p>
  
  <p>a:4:{s:23:"WebAuthenticationDetail";a:1:{s:14:"UserCredential";a:2:{s:3:"Key";s:16:"<strong>KEY</strong>";s:8:"Password";s:6:"<strong>PASSWD</strong>";}}s:12:"ClientDetail";a:2:{s:13:"AccountNumber";s:9:"<strong>ACCNUMBER</strong>";s:11:"MeterNumber";s:9:"<strong>METER NUMBER</strong>";}s:7:"Version";a:4:{s:9:"ServiceId";s:3:"crs";s:5:"Major";s:1:"9";s:12:"Intermediate";s:1:"0";s:5:"Minor";s:1:"0";}s:17:"RequestedShipment";a:11:{s:11:"DropoffType";s:14:"REGULAR_PICKUP";s:13:"ShipTimestamp";s:25:"2011-12-08T20:33:05+00:00";s:13:"PackagingType";s:14:"YOUR_PACKAGING";s:17:"TotalInsuredValue";a:2:{s:7:"Ammount";d:129.06999999999999317878973670303821563720703125;s:8:"Currency";s:3:"USD";}s:7:"Shipper";a:1:{s:7:"Address";a:2:{s:10:"PostalCode";s:5:"07094";s:11:"CountryCode";s:2:"US";}}s:9:"Recipient";a:1:{s:7:"Address";a:3:{s:10:"PostalCode";s:5:"10033";s:11:"CountryCode";s:2:"US";s:11:"Residential";b:1;}}s:22:"ShippingChargesPayment";a:2:{s:11:"PaymentType";s:6:"SENDER";s:5:"Payor";a:2:{s:13:"AccountNumber";s:9:"368675440";s:11:"CountryCode";s:2:"US";}}s:16:"RateRequestTypes";s:4:"LIST";s:12:"PackageCount";s:1:"1";s:13:"PackageDetail";s:19:"INDIVIDUAL_PACKAGES";s:25:"RequestedPackageLineItems";a:1:{i:0;a:1:{s:6:"Weight";a:2:{s:5:"Value";d:145.3600000000000136424205265939235687255859375;s:5:"Units";s:2:"LB";}}}}}</p>
