title: Laravel Shopify API Wrapper, refused the connection
body: <p>I have a project on building a shopify app through <strong>"embedded SDK"</strong> The app was installed successfully but it does not redirect back to admin where the app should show the API call result. When I try to access the app that I installed the frame will just display <strong>The server refused the connection.</strong> </p>
  
  <p>I used the joshrps/laravel-shopify-API-wrapper for my laravel project. This is my controller where I make a request to install the app <a href="http://pastebin.com/zEn96SWs" rel="nofollow">http://pastebin.com/zEn96SWs</a> , this is my redirect uri when the app is successfully installed:</p>
  
  <pre><code>Route::get('shopify',function(){
      $sh = App::make('ShopifyAPI',[
          'API_KEY'=&gt;'a1568bd534e2e7a88b21d693bdc73afe',
          'API_SECRET'=&gt;'b15f951478db59369da196e77ea23fb7',
          'SHOP_DOMAIN'=&gt;'shinobishop.myshopify.com']);
      $code = Input::get('code');
      try`enter code here`
      {
          $accessToken = $sh-&gt;getAccessToken($code);
      }
      catch (Exception $e)
      {
          echo '&lt;pre&gt;Error: ' . $e-&gt;getMessage() . '&lt;/pre&gt;';
      }
  ));
  </code></pre>
  
  <p>I hope you can help me with this issue. Its my first time using shopify API on projects.</p>
