How to retrieve associated products for configurable product with Magento SOAP API2?

Question

I'm trying to get all the associated products for a configurable product using the Magento SOAP API v2. The catalogProductLink call looks close, but doesn't handle configurable types. I don't see any other calls that contain the associated product and configurable type information for a product. How have others solved this issue?

I'm using Magento version 1.6 and the SOAP API V2 with Java.

I looked deeper into this solution and realized that you may need to override the API model (Mage_Catalog_Model_Product_Api) to achieve the results you're looking for.

In the items function (around line 90), you can do something like this:

foreach ($collection as $product) {
    $childProductIds = Mage::getModel('catalog/product_type_configurable')->getChildrenIds($product->getId());
    $result[] = array(
        'product_id' => $product->getId(),
        'sku'        => $product->getSku(),
        'name'       => $product->getName(),
        'set'        => $product->getAttributeSetId(),
        'type'       => $product->getTypeId(),
        'category_ids' => $product->getCategoryIds(),
        'website_ids'  => $product->getWebsiteIds(),
        'children'  => $childProductIds[0],
    );
}
