The eBay Feedback API provides developers a means to monitor account-level Feedback data, specifically Detailed Seller Ratings (DSR's). The Feedback Service generates DSR summary reports for sellers based on a variety of criteria, such as time period, listing category, transaction information, or specific shipping details.
The Feedback Service uses an asynchronous programming model. There are "create" calls for specifying the criteria for generating the reports and a single "get" call, getDSRSummary, to retrieve the generated reports, since reports take too much time to generate to return them in the response of the create calls. The XML response for the create calls contains a job ID, which is used as input for the get call to check completion status and/or to retrieve the DSR summary report.
