Now sellers can view the success rates as a percentage of successful API calls for each API group (e.g. Items, Promotions, Orders) with the new Analytics Dashboard.
Sellers can also view insights about error messages generated per API group. You can filter by error type (e.g. 400, 404 or 500), or view all errors, as well as get the API call volume for that API group.
To get to the API Analytics dashboard, log into the developer portal, and select API Analytics in the left pane.
