Find the answer to your question
GetSellerList is not returning some of my store items, but they were returned a few days ago. Why is this happening?
Store Items that are listed with the ListingDuration of GTC have a rolling EndTime. Hence if you make a call to GetSellerList with the EndTime filter you need to ensure that the EndTime for item is within the range that you specify.
Item did not sell and the seller did not end the item,
hence it got relisted automatically and it now has a new EndTime of 2006-10-03T19:32:24.000Z
Now you need to modify the EndTime filter so that it includes the new EndTime such as:
Using the previous filter of September will not return the item.
