Thank you once again for your patience as we worked to resolve the problems with the API. We apologize for any inconvenience this may have caused you.
The XML was fixed this weekend and we consider the issues resolved and expect no further updates.
We are committed to adding the Prosper calculated ROI values. We will update you with more information regarding the Prosper calculated ROI values as soon as possible.
I’m not holding my breath on the ROI I can do too many cool things with the API bidding to be wait until the ROI is available to kick into action… Thanks for fixing the real issues Prosper.
