I am tasked right now to figure out a way my company can do a product search by UPC so we can grab the ASIN (Amazon Serial Identification Number). I was hoping someone could lead me in the right direction into what Amazon API I could use to do this. I would think they would have some API that allows a product search.
Also I am looking to implement this in C#/.NET.
Thanks for the help! -Lewis
You're looking for the Product Advertising API, more specifically the ItemLookup API with an IdType of UPC.
Make sure you read the licensing terms of the API though, as they are quite restrictive.
