A unique identifier for a Feedback record. Buying and selling partners leave feedback for one another after the completion of an order. Feedback is left at the order line item level, so a Feedback comment for each order line item in a Combined Payment order is expected from the buyer and seller. A unique FeedbackID is created whenever a buyer leaves feedback for a seller, and vice versa. A FeedbackID is created by eBay when feedback is left through the eBay site, or through the LeaveFeedback call. FeedbackIDs can be retrieved with the GetFeedback call. In the RespondToFeedback call, FeedbackID can be used as an input filter to respond to a specific Feedback comment. Since Feedback is always linked to a unique order line item, an ItemID/TransactionID pair or an OrderLineItemID can also be used to respond to a Feedback comment.
