Responses form the JSON API web service contain a list of results corresponding to each of the command that was submitted. Each result may contain either a "result" : { } pair that lists the command return values (if any), or the "errors" : [ ] pair that lists the errors returned by the command.

If an error occurs during processing a request having multiple commands, the service stops execution of further commands and sends a response object with the results of preceding commands and the error description for the current command.
