I am trying to display the amazon products of a specific category on my website using amazon product advertising api. I am writing code is asp.net. I am being able to successfully retrieve its price, title,image,url.I also want to get its product id that amazon uses.I had a look at its documentation in which they had mentioned something about the UPC(universal product code) and ASIN.But they have explained look up search based on UPC and ASIN. I am too confused as to how to get its product id.

+ "&Sort=relevancerank"
+ "&ResponseGroup=ItemAttributes,Images"
