Every product recieves a unique ID, shown on the left on the product page screenshot. I do not choose this nunmber, the number is assigned by the system.
Now I am trying to create a pricefeed with XML template and I need to provide unique product ID in the pricefeed, however my own SKU is too long so I want to use Magentos product ID.
What is the actual internal magento 'attribute code' for the magento product ID to the left? I've checked Product Export Attributes Reference where this specific magento product ID isn't listed.
