Magento product.create websites argument - api

Question

I have a question about the websites argument in the magento api.
Nowhere can I find an explanation of what this variable is.
Does this variable represent a storeview? a store? a website?
Where in the api can I retrieve a list of available options?
If I cannot retrieve a list from the API, where in the backend menu can I find the static variable that I can use?
Do I need the website ID or storeID?
I use soap v1
function call($which,$vars=null)
{
// retourneer de output soap client api call
if($vars !== null)
{
return $this->soapclient->call($this->sessiontoken,$which,$vars);
}
else
{
return $this->soapclient->call($this->sessiontoken,$which);
}
}
function createProduct($productname,
$websites,
$shortdescription,
$description,
$status,
$weight,
$tax_class_id,
$categories,
$price,
$attributesetid,
$producttype,
$sku)
{
$attributeSets = $this->call('product_attribute_set.list');
$set = current($attributeSets);
try
{
$x = $this->call('product.create', array($producttype, $set['set_id'], $sku, array(
'name' => $productname,
// websites - Array of website ids to which you want to assign a new product
'websites' => $websites, // array(1,2,3,...)
'short_description' => $shortdescription,
'description' => $description,
'status' => $status,
'weight' => $weight,
'tax_class_id' => $tax_class_id,
'categories' => $categories, //3 is the category id(array(3))
'price' => $price
);));
}
catch(Exception $e)
{
$x = 0xABED + 0xCAFE + 0xBAD + 0xBED * 0xFACE;// abed went to a cafe... the alcohol went bad.... he stumbled into bed and fell face down...
}
return $x;
}

Looking at Mage_Catalog_Model_Product_Api::create():
public function create($type, $set, $sku, $productData, $store = null)
{
//[...]
$product = Mage::getModel('catalog/product');
$product->setStoreId($this->_getStoreId($store))
->setAttributeSetId($set)
->setTypeId($type)
->setSku($sku);
//[...]
$this->_prepareDataForSave($product, $productData);//this does some processing
Now, looking at Mage_Catalog_Model_Product_Api::_prepareDataForSave():
protected function _prepareDataForSave($product, $productData)
{
if (isset($productData['website_ids']) && is_array($productData['website_ids'])) {
$product->setWebsiteIds($productData['website_ids']);
}
//....
we see that website_ids (numeric array) are expected
