I am converting my old Trading API code to the new Fulfillment API code for processing our orders. However, I have noticed that the new API does not supply the eBay Unique Code in the second line of the address like the old API does. How can I obtain the eBay Unique Code for an order using the new API? I realise that it is not really necessary, but it seems a shame to lose a feature (if it even actually does anything!).
For those that don't know, the eBay Unique Code looks something like "ebaydhur3fr" and is visible when viewing order details in Seller Hub.
