we are building an inventory app, and our SKUs are related to ebay item IDs.... when an item relists, we use the RelistParentID to maintain this association with our SKU on our end.
However, if an item is copied to create a new item listing, this RelistParentID comes along with the copy, breaking our association of ebay ID to SKU, because now multiple listings carry the same RelistParentID
How can I tell if an item is a copy of another, and therefore not really a "relisted" item? I suppose I could pull the parent item and do some comparison myself, but I figured there should be a way to determine this from the API data, no?
Much appreciated if anyone has a clue about solving this. Personally, I don't see why ebay would even do this - seems like a huge blunder on their part. Sellers copy items just to make listing similar items easier - I can't understand why the parent ID would be passed... it makes no sense.
