Edit file class.cart.api.php

Edit file /includes/classes/class.cart.api.php

Find line public function AddItem( line number 1164 and add in the end of parameters new parameter $productPrivateData=null

It will look like:
public function AddItem($productId, $quantity=1, $variationDetails=null, $configurableOptions=array(), $cartItemId=null, $options=array(), $parentId=null, $reorder=false, $productPrivateData=null)

Next find cartProduct array (line 1319):
        $cartProduct = array(
            'product_id' => $productId,
            'variation_id' => $variation,
            'options' => $variationOptions,
            'quantity' => $quantity,
            'product_name' => $product['prodname'],
            'product_code' => $productCode,
            'product_price' => $productPrice,
            'original_price' => $originalPrice,
            'default_currency' => $defaultCurrency['currencyid'],
            'customer_group' => $customerGroup,
        );

add there 'product_private_data' => $productPrivateData

it will look like:
        $cartProduct = array(
            'product_id' => $productId,
            'variation_id' => $variation,
            'options' => $variationOptions,
            'quantity' => $quantity,
            'product_name' => $product['prodname'],
            'product_code' => $productCode,
            'product_price' => $productPrice,
            'original_price' => $originalPrice,
            'default_currency' => $defaultCurrency['currencyid'],
            'customer_group' => $customerGroup,
            'product_private_data' => $productPrivateData
        );

Edit file class.cart.php

Edit file /includes/classes/class.cart.php

Find line:
$cartItemId = $this->api->AddItem($product_id, $qty, $variation, $configurableFields, null, $options, null, false);

change it like:
$cartItemId = $this->api->AddItem($product_id, $qty, $variation, $configurableFields, null, $options, null, false, $productPrivateData);

And add this before it:
            $productPrivateData = '';
            if(isset($_REQUEST['product-private-data'])) {
                $productPrivateData = $_REQUEST['product-private-data'];
            }

Add sale tracking code into file class.handler.php in googlecheckout method
Edit file /modules/checkout/googlecheckout/class.handler.php

Find this code around line 925:
if (!$completed) {
            $GLOBALS['ISC_CLASS_LOG']->LogSystemError($this->logtype, sprintf(GetLang('GoogleCheckoutCantCompleteOrder'), isc_html_escape($pendingToken), isc_html_escape(var_export($completed, true))));
            return;
        }

add next code right after:

  foreach($cartContent[$vendorId][0] as $cartItemId => $product) {
    $productid = $product['data']['productid'];
    $productPrivateData = $product['product_private_data'];
  }

  if (strlen($productPrivateData) == 40) { 
      $accountId = substr($productPrivateData, 0, 8); 
      $visitorId = substr($productPrivateData, 8, 32);
  } else { 
      $visitorId = $productPrivateData;
      $accountId = 'default1';
  }
  //PAP api tracking code
  include 'PapApi.class.php';
  $saleTracker = new Pap_Api_SaleTracker('http://www.yoursite.com/affiliate/scripts/sale.php');
  $saleTracker->setAccountId($accountId);
  $saleTracker->setCookieValue($visitorId);
  $sale1 = $saleTracker->createSale();
  $sale1->setTotalCost($vendorInfo['itemTotal']);
  $sale1->setOrderID($order['orderid']);
  $sale1->setProductID($productid);
  $saleTracker->register();
  //End PAP api tracking code

Below, you can see an example of how it will look like, if you want to create a transaction for each product:
This tracking method is using PAP API. Therefore you need to have your actual PapApi.class.php file in directory /modules/checkout/googlecheckout/
(You can download it from your merchant panel > start > tools > integration > api integration > Download PAP API).
