Error Handling
When the API detects an error with an API call, the EWA will return non-200 status code in response, e.g., 500(Internal Error), or 400(Bad Request), and others.
Details of the error are defined in an XML data package, error_info which will return to client application. The error_info is described in Web API XML Data Package Definitions section in details. Error information: error_info XML Data.
