Tasks

•   value

  An industry-standard value that uniquely identifies the product. The valid
  values are dictated by the Type property. Required if Type is specified. Max
  length 13 for ISBN (as of February 2007), 13 for EAN, 12 for UPC, and 4000 for
  ProductID. No max length for ticket keywords (but passing too much data can
  result in “no match found” errors).
  
  
  
  For AddItem and related calls:
  If the primary and secondary categories are both catalog-enabled, the value must
  apply to the primary category. Event tickets listings support a set of keywords
  that uniquely identify the listing. The ticket keywords specify the event name
  (the title shown on the ticket), venue name, and event date and time. See the
  eBay Web Services guide for more information and validation rules. For
  convenience, you can pass an eBay product ID as input (not limited to media
  categories).
  
  
  
  Required for Half.com listing use cases, and this can only be an ISBN, UPC, or
  EAN value.
  
  
  
  For GetSellerPayments output only:
  Also see AlternateValue, which is returned if the catalog defines multiple
  ISBN values (e.g., one for ISBN-13 and one for ISBN-10). Please note that
  some catalogs return ISBN values that are not 10 or 13 characters, and some
  values contain non-alphanumeric symbols (e.g., $).

  property
•   returnSearchResultOnDuplicates

  Applicable for listing use cases only (not buy-side searching).
  Indicates what eBay should do if more than one product matches
  the value passed in Value. Only takes effect when more than one
  match is found. If true, the response should include an error
  and all matching product IDs. If false, the response should include
  an error but should not return the matching product IDs.
  This field is also applicable when listing Half.com items.

  property
•   type

  The kind of identifier being used. The choices are listed
  For requests, required if Value is specified.
  For Half.com listing use cases, only ISBN, UPC, and EAN are supported.

  property
•   alternateValue

  An industry-standard value that provides an alternate identification for
  the product, if any. Currently, this only returns an alternate ISBN
  value. If the catalog defines both an ISBN-13 and ISBN-10,
  then the ISBN-13 is returned in Value and the ISBN-10 is returned in
  AlternateValue. (That is, the ISBN-13 is considered to be the preferred
  identifier.) If the catalog only defines one ISBN, it is returned in
  Value (and AlternateValue is not returned). Please note that some
  catalogs return ISBN values that are not 10 or 13 characters,
  and some values contain non-alphanumeric symbols (e.g., $).
