How to retrieve wishlist data in magento using REST API

Hello All,

I am writing an REST API in magento to retrieve the wishlist data. I have written the below code, I got an "Invalid auth/bad request (got a 500, expected HTTP/1.1 20X or a redirect)" error message. Please suggest what is the issue.

PHP Code:

---

$customer = Mage::getSingleton('customer/session')->getCustomer();

$wishList = Mage::getSingleton(‘wishlist/wishlist’)->loadByCustomer($customer);
$wishListItemCollection = $wishList->getItemCollection();
if (count($wishListItemCollection)) {
 $productId = array();
 foreach ($wishListItemCollection as $item) {
 $product = $item->getProduct();
 $productId[] = $product->getId();
 }
 }
return $wishListItemCollection; 


---

Thanks

You meet the problem with api authentication but you show here the code for the wishlist retrieve. You need to check auth to get it work success first.
