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 (transaction) level, so a Feedback comment for each 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.

Unique identifier for an eBay item listing. A listing can have multiple order line items (transactions), but only one ItemID. An ItemID can be paired up with a corresponding TransactionID and used as an input filter to respond to a Feedback comment in the RespondToFeedback call. Unless the specific Feedback record is identified by a FeedbackID or an OrderLineItemID in the request, an ItemID/TransactionID pair is required.

OrderLineItemID is a unique identifier for an eBay order line item and is based upon the concatenation of ItemID and TransactionID, with a hyphen in between these two IDs. Since Feedback is always linked to a unique order line item, an OrderLineItemID can be used to respond to a Feedback comment.

Unless an ItemID/TransactionID pair or a FeedbackID is used to identify a Feedback record, the OrderLineItemID must be specified.

Textual comment that the user who is subject of feedback may leave in response or rebuttal to the Feedback comment. Alternatively, when the ResponseType is FollowUp, this value contains the text of the follow-up comment.

Specifies whether the response is a reply or a follow-up to a Feedback comment left by the user identified in the TargetUserID field.

The eBay user ID of the caller's order partner. The caller is either replyting to or following up on this user's Feedback comment.

Unique identifier for an eBay order line item (transaction). A TransactionID can be paired up with its corresponding ItemID and used as an input filter to respond to a Feedback comment in the RespondToFeedback call. Unless the specific Feedback record is identified by a FeedbackID or an OrderLineItemID in the request, an ItemID/TransactionID pair is required.
