# GTIN/ISBN/UPC to Walmart Item ID Lookups

BlueCart API allows you to retrieve Walmart Product Data by GTIN, ISBN or UPC code when making a  `type=product`  query. There is no additional charge for this service.

To lookup Walmart Product Data by GTIN, ISBN or UPC code you simply use the  `gtin`  parameter instead of the  `item_id`  when making a  `type=product`  request.

When the  `gtin`  parameter is supplied BlueCart will attempt to look up the GTIN/ISBN/UPC on Walmart before then retrieving product details for the resultant  `item_id` .

`type=product&gtin=070330682719`
