In Magento, what's the performance of extending the rest/products api, to retrieve the tags and attributes of the products in the returned list?

Question

The only way I can think of doing it is to retrieve the products, and then in the script call the other APIs to retrieve the information I need, before finally returning the response. I'm still somewhat new to Magento, and this seems to be quite heavy on performance. Is the above solution effective in performance, or is there a better way of retrieving the tags,etc.. from the rest/products api? Essentially, what I'm looking for is something along those lines: The current API returns: ``` { 337: { entity_id: "337" type_id: "simple" sku: "ace000" color: "15" gender: "93" material: "130" jewelry_type: null description: "Gunmetal frame with crystal gradient polycarbonate lenses in grey. " meta_keyword: null short_description: "A timeless accessory staple, the unmistakable teardrop lenses of our Aviator sunglasses appeal to everyone from suits to rock stars to citizens of the world." name: "Aviator Sunglasses" meta_title: null meta_description: null regular_price_with_tax: 319.34 regular_p…

Accepted Answer

You should extend the existing product REST api model and override the method `_prepareProductForResponse` to include tags and other data

Check here overriding rest model http://web.archive.org/web/20130512072025/http://magepim.com/news/Extending-the-Magento-REST-API-part-1_13

Your model definition:

```
Namespace_yourmodule_Model_Catalog_Api2_Product_Rest extends Mage_Catalog_Model_Api2_Product_Rest {

protected function _prepareProductForResponse(Mage_Catalog_Model_Product $product)
{
 // keep the existing code as it is

// now add new code to add tags

$productData['tags'] = Mage::getModel('tag/tag')->getResourceCollection()
    ->addPopularity()
    ->addProductFilter($product->getId());

// in the end 
 $product->addData($productData);
}
```
