The Analytics API provides data and information about a seller and their eBay business. The resources and methods in this API let sellers review information on their listing performance, metrics on their customer service performance, and details on their eBay seller performance rating. The three resources in the Analytics API provide the following data and information: Customer Service Metric – Returns data on a seller's customer service performance as compared to other seller's in the same peer group. Traffic Report – Returns data that shows how buyers are engaging with a seller's listings. Seller Standards Profile – Returns data pertaining to a seller's performance rating. Sellers can use the data and information returned by the various Analytics API methods to determine where they can make improvements to increase sales and how they might improve their seller status as viewed by eBay buyers.

Note: This is a (Limited Release) API available only to select developers approved by business units. The Logistics API resources offer the following capabilities: shipping_quote – Consolidates into a list a set of live shipping rates, or quotes, from which you can select a rate to ship a package. shipment – Creates a "shipment" for the selected shipping rate. Call createShippingQuote to get a list of live shipping rates. The rates returned are all valid for a specific time window and all quoted prices are at eBay-negotiated rates. Select one of the live rates and using its associated rateId, create a "shipment" for the package by calling createFromShippingQuote. Creating a shipment completes an agreement, and the cost of the base service and any added shipping options are summed into the returned totalShippingCost value. This action also generates a shipping label that you can use to ship the package. The total cost of the shipment is incurred when the package is shipped using the supplied shipping label. Important! Sellers must set up a payment method via their eBay account before they can use the methods in this API to create a shipment and the associated shipping label.
