503 throttling error

This 503 error indicates that your request is being throttled. When you use the client library, the response is parsed and a MarketplacewebService exception with all data included is thrown.

How to troubleshoot

Check the throttling limit in the API documentation for the type of request you are submitting. Set up your retry logic to resend the request when the appropriate amount of time has passed to prevent throttling.
