configurable product options are not added to cart using magento soap api

Question

I have tried to add a configurable product in using magento soap api. I am using the following code to add

 $product = array(
             'product_id' => 23,    // simple product id
             'sku' => 'H001-Yellow-22',
             'qty' => '1',

            'super_attribute' => Array( [92] => 10, [134] => 3 )  // color is yellow                                                 and
size is 22        

        );
$client->shoppingCartProductAdd($session,$cartId,array($product),'1');

Instead of superattribute, i gave like this also

'super_attribute' => array(
                0 => array(
                'key' => 92,
                'value' => 10
                ),
                1 => array(
                'key' => 134,
                'value' => 3
                )
            )

but the options are not added to the cart. Why the options are not added to the cart? How the options to be added?

Answer 1

finally my config product has added to cart using magento api

$product = array(
            'product_id' => 19,   // config product id
            'sku' => 'H001',
            'qty' => '1',

           'super_attribute' => array(
                0 => array(
                'key' => 92,        //attribute id
                'value' => 10       //value
                ),
                1 => array(
                'key' => 134,
                'value' => 3
                )
            )
        );  

$client->shoppingCartProductAdd($session,$cartId, array($product));

Answer 2

It didn't work for me the way described in the accepted answer. So I browsed through the code in magento. It actually works just the same way as adding a product to cart works in the browser:

$proxy->call( $sessionId, 'cart_product.add', array( $shoppingCartIncrementId, [ [ 'product_id' => 83, 'qty' => 1, 'super_attribute' => [ '501' => '36', // attributeId => valueId '502' => '41' ] ] ] ) );

The keys of the super_attribute array are the attribute IDs of the configurable attributes (e.g. the color attribute's ID). The values are the the value IDs (e.g. the red value's ID).

This is a minimalistic example, I only used the required attributes for the SOAP call. I'm using SOAP API v1, but you could as well do it with SOAP API v2 using shoppingCartProductAdd.
