Magento Cart API not showing prices

Question

I am attempting to use the Magento Enterprise 1.10 XML-RPC API to handle cart/catalog functions outside of the Magento installation. The issue that I am having is when I add to cart. I can connect just fine to the API endpoint, login, and retrieve data. The following is the code that I am using to discover the workings of the Magento API.

<?php    
   require $_SERVER['DOCUMENT_ROOT'].'/Zend/XmlRpc/Client.php';

   $url = 'http://mymagento.com/api/xmlrpc';
   $user = 'apiuser';
   $pass = 'apipass';

   $proxy = new Zend_XmlRpc_Client( $url );
   $sess = $proxy->call( 'login', array( $user, $pass ) );
   $cartId = $proxy->call( 'call', array( $sess, 'cart.create', array( 1 ) ) );

   $pList = $proxy->call( 'call', array( $sess, 'product.list', array() ) );
   $cList = $proxy->call( 'call', array( $sess, 'customer.list', array() ) );

   $cList[0]['mode'] = 'customer';

   $setCart = $proxy->call( 'call', array( $sess,
      'cart_customer.set',
      array( $cartId, $cList[0] ) ) );

   foreach( $pList as $prod)
   {
      if( $prod['product_id'] == 5 )
      {
          $prod['qty'] = 5;
          $addCart = $proxy->call( 'call', array( $sess, 
              'cart_product.add',
              array( $cartId, $pAdd ) ) );
      }
   }

   $cList = $proxy->call( 'call', array( $sess, 'cart.info', array( $cartId ) ) );
   print_r( $cList );

Outputs:

            [discount_amount] => 0.0000
            [base_discount_amount] => 0.0000

However, I am to just call the following using the same above session

<?php
    $pInfo = $proxy->call( 'call', array( $sess, 'catalog_product.info', '5' ) );
    print_r( $pInfo );

I get the following information about the product:

[product_id] => 5
[sku] => product1
[set] => 9
[type] => virtual
[categories] => Array
    (
    )

[websites] => Array
    (
        [0] => 1
    )

[type_id] => virtual
[name] => product
[description] => Test
[short_description] => Test
[news_from_date] => 
[old_id] => 
[news_to_date] => 
[status] => 1
[visibility] => 4
...
[created_at] => 2011-05-25 15:11:34
[updated_at] => 2011-05-25 15:11:34
...
[price] => 10.0000

In the end, the API sees that the price of the item is in fact $10.00, but when added to the cart via API the prices are not properly reflected.

Answer 1

Just so it can be an officially answered question, here is the solution found, http://magentocommerce.com/boards/viewthread/227044 I spent two days searching for this, and today come up with an obscure search term to try and find the solution

Answer 2

I've been looking at this issue for a couple days now. It didn't make sense to me that if you add a product to your cart through the normal web interface [ie Mage_Checkout_CartController::addAction() ]. It knows the price without you providing an address. I finally found the difference between the two. In addAction() they create an instance of Mage_Checkout_Model_Cart, add the product to that, and save it. In the api they use Mage_Sales_Model_Quote instead. If you look at Mage_Checkout_Model_Cart::save() you will see these two lines:

$this->getQuote()->getBillingAddress();
$this->getQuote()->getShippingAddress();

These two lines actually create empty Mage_Sales_Model_Quote_Address objects that get saved into the db.

If you are willing/able to modify magento's code, you can modify Mage_Checkout_Model_Cart_Api::create() and add a call to these two methods before $quote->save() and the api and the web interface will work the same way.

I have only tested this a little bit, but I really think this is a bug and not a feature. I'll see about getting this in front of actual magento devs and maybe they'll include it in the next release.
