How can I create a configurable product using the Magento api?
Here's a really good tutorial that walks you through patching the API, so you can use the API directly to create the configurable product, and assign simple products to it as well.
Good luck
This is possible with the magento-improve-api plugin. If you need to control which attributes your configurable product is configurable across, you'll need one of the forks of that plugin in

$proxy = new SoapClient('http://magentohost/api/soap/?wsdl');
$sessionId = $proxy->login('apiUser', 'apiKey');
// default attribute set in my install is 4
$attribute_set_id = 4;
// configurable product to create
$product_sku = 123456789012;
$newProductData = array(
'name' => 'name of product',
// websites - Array of website ids to which you want to assign a new product
'websites' => array(1), // array(1,2,3,...)
'short_description' => 'short description',
'description' => 'description',
'price' => 12.05
);
$proxy->call($sessionId, 'product.create', array(
'configurable',
$attribute_set_id,
$product_sku,
$newProductData
));
The hard part is assigning simple products to your configurables (not supported via the api). Here's a method for assigning simples to configurables directly
