Q: Can I leave 'follow-up' feedback with the eBay API A: The eBay API does not currently support leaving 'follow-up' feedback. This also implies that the eBay SDK for Java and eBay SDK for Windows do no support this functionality. Feedback can be left for a seller and for a buyer via the API. Rebuttal feedback is not currently supported in the eBay API.
The LeaveFeedback function does not support leaving responses (rebuttals) and follow-up comments. Buyers and sellers can use the eBay Web site to respond to feedback left by others.
