As of February 2010, the lowest supported Trading API version is 577. (Version 577 was released in August 2008.) Objects that were deprecated prior to version 577 no longer work, or may stop working at any time without notice. We recommend that you remove deprecated objects from your applications as soon as possible.

Here are examples of objects that were deprecated 18-24 months ago:

• In GetUser: User.CharityAffiliations (use User.SellerInfo.CharityAffiliationsDetails instead)
• In GetAdFormatLeads: AddFormatLead.FirstName, LastName, Phone, Phone2 (use AddFormatLead.Address instead)
• In GetFeedback: SellerAverageRatingDetailArray (use SellerRatingSummaryArray instead)
• In AddItem and related calls: Item.BuyerRequirements (use Item.BuyerRequirementDetails instead)
• In AddItem, GetSearchResults, and related calls: DigitalDeliveryDetails
