It seems that sites like https://130point.com/sales/ is able to get best offer prices on a consistent basis. Haven't been able to figure out how they are doing it, but supposedly it requires authenticating in to eBay. Best offer prices are absolutely crucial, especially in my area (collectibles) as people commonly post items for sale at outrageous prices and accept best offers at 50-80% of the listed price. Representing the listed price as the sales price is practically criminal and can cause inflated listing asking prices. I'd think providing API access to best offer prices (AND prices accepted through eBay messaging) should be a top priority.
@michow3321 what is your email? It would be great to hear about what you are working on, I could possibly help you with this.
I'm also curious about this. GetBestOffers is *documented* as doing this:
"If the user is neither the seller nor a bidder for a listing--The user sees all offer prices and currencies of all bidders IF the listing has ended. Otherwise, the user sees nothing. No email ids are returned."
But it does not actually return the information it claims to return, it returns an entry for each offer but not the actual price offered. I have also not once managed to get it to return an offer with Status "Accepted", even for items which had ludicrous list prices and which I'm almost sure must actually have sold for an offer price.
I'm trying to track sold prices of a specific category of items (Pokemon games) accurately, but it's hard because they are very often sold with offers accepted and I have no idea what those listings really sold for.
