Find the answer to your question
I have a catalog of MPNs and would like to match mine against eBay's so I can list my inventory against catalogs. How do I find if my products have a match in eBay's catalog?
To find if your MPNs have a match in our catalogs, use the FindProducts call. Here is the query to search for products by MPN.
If a match is found, the response will have the following tag : <ProductID type="Reference">115383099</ProductID>
List your item by passing the BrandMPN in the AddFixedPriceItem request.
