How to find the Product Reference ID before listing an item?
Trying to update an application we use that hasn't been touched in a while. Basically, the application automatically lists phones that come into our inventory. With the new product-based system, we're now getting the "you must select a product from the eBay catalog" error. I assume this means we must set the "ProductReferenceID", yes? How should I go about finding the productReferenceID for a specific type of phone within the SDK? For example, if my app can see that I'm attempting to list a black iPhone 7, how can the app find the correct reference ID? We store the UPC of the device, can I search by that? What calls am I looking for here?
