If you want to send json data back from magento end you need to overwrite each function in magento API

For Example catalogProductList() method

Copy file

app/code/core/Mage/Catalog/Model/Product/Api.php

To

app/code/local/Mage/Catalog/Model/Product/Api.php

And modify below function

public function items($filters = null, $store = null)
{
 $collection = Mage::getModel('catalog/product')->getCollection()
 ->addStoreFilter($this->_getStoreId($store))
 ->addAttributeToSelect('name');
 /** @var $apiHelper Mage_Api_Helper_Data */
 $apiHelper = Mage::helper('api');
 $filters = $apiHelper->parseFilters($filters, $this->_filtersMap);
 try {
 foreach ($filters as $field => $value) {
 $collection->addFieldToFilter($field, $value);
 }
 } catch (Mage_Core_Exception $e) {
 $this->_fault('filters_invalid', $e->getMessage());
 }
 $result = array();
 foreach ($collection as $product) {
 $result[] = array(
 'product_id' => $product->getId(),
 'sku' => $product->getSku(),
 'name' => $product->getName(),
 'set' => $product->getAttributeSetId(),
 'type' => $product->getTypeId(),
 'category_ids' => $product->getCategoryIds(),
 'website_ids' => $product->getWebsiteIds()
 );
 }
 return Mage::helper('core')->jsonEncode($result); 
}

• vellai durai: Thanks for the response.. I have added the code but no data is fetched the output i am getting is array(0) { }
• Minesh Patel: You have products in your shop?
• vellai durai: yes.. The output of the default code is array(1429) { [0]=>
• Minesh Patel: Copy original function items () from core file and just replace return statement
• vellai durai: Getting same output

To decode JSON into an array you can use the following code:

$array = Mage::helper('core')->jsonDecode($result);

To encode an array into JSON you can use the following code:

$json = Mage::helper('core')->jsonEncode($result);
