DisputeExplanation: An explanation of the dispute that supplements the DisputeReason. The allowed value depends on the value of DisputeReason.
DisputeReason: The top-level reason for the Unpaid Item Dispute. DisputeReasonCodeType has several possible values. However, only BuyerHasNotPaid and TransactionMutuallyCanceled apply to AddDispute--you can only use AddDisputeCall to create Unpaid Item disputes.
ItemID: The eBay ID of the item in dispute, an item which has been sold but not yet paid for.
TransactionID: The eBay ID of a transaction, created when the buyer committed to purchasing the item. A transaction ID is unique to the item but not across the entire eBay site. The transaction ID must be combined with an item ID to uniquely identify an item.
