since v12.12

The extension point RatingReceivedEventListener is a Java interface that can be implemented to perform actions within the novomind iAGENT routing process after a rating for a chat or ticket has been received.

All required information about the chat or ticket and further information about the rating is provided by the ChatRatingReceivedEvent or TicketRatingReceivedEvent parameters, which are passed to the various method calls. If you don't need to distinguish the different rating events you can just override the method with the RatingReceivedEvent parameter. Otherwise override the methods that suit your needs.
