title: Paypal Checkout Express doesn't show the order details
body: <p>I'm using the lib <a href="https://github.com/paypal/PayPal-PHP-SDK" rel="nofollow noreferrer">PayPal-PHP-SDK</a> on Laravel 4</p>
  
  <p>and I have a problem with showing the order details.
  I followed the steps from <a href="https://developer.paypal.com/docs/integration/web/web-checkout/" rel="nofollow noreferrer">Paypal Web Checkout</a>
  and it doesn't showing me the order details.</p>
  
  <p>it says "You'll be able to see your order details before you pay."

  <p>This is the method when I get the link to the payment:</p>
  
  <pre><code>public function checkout()
  {
      $apiContext = new ApiContext($this-&gt;cred, 'Request' . time());
      $apiContext-&gt;setConfig($this-&gt;sdkConfig);
  
      $payer = new Payer();
      $payer-&gt;setPaymentMethod("paypal");
  
      $amount = new Amount();
      $amount-&gt;setCurrency("EUR");
      $amount-&gt;setTotal("10");
  
      $transaction = new Transaction();
      $transaction-&gt;setDescription("Example");
      $transaction-&gt;setCustom('abv');
      $transaction-&gt;setAmount($amount);
  
      $redirectUrls = new RedirectUrls();
      $redirectUrls-&gt;setReturnUrl(URL::to('/') . '/payment/success/');
      $redirectUrls-&gt;setCancelUrl(URL::to('/') . '/payment/cancel/');
  
  
      $payment = new Payment();
      $payment-&gt;setIntent("sale");
      $payment-&gt;setPayer($payer);
      $payment-&gt;setRedirectUrls($redirectUrls);
      $payment-&gt;setTransactions(array($transaction));
  
      $payment-&gt;create($apiContext);
  
      print $payment-&gt;getApprovalLink();
  
  }
  </code></pre>
