Status Codes

When you call any of the REST operations, the response returns one of the standard HTTP status codes defined in the following table.:

HTTP Status Code	Description
200 OK	The request was completed successfully A 200 status is returned for a successful GET or POST method.
400 Bad Request	The request could not be processed because it contains missing or invalid information (such as a validation error on a parameter or a missing required value).
401 Unauthorized	The request is not authorized. The authentication credentials included with this request are missing or invalid.
403 Forbidden	The user can't be authenticated. The user does not have authorization to perform this request.
404 Not Found	The request includes a resource URI that does not exist.
405 Method Not Allowed	The HTTP verb specified in the request (DELETE, GET, POST, PUT) is not supported for this request URI.
415 Unsupported Media Type	The client's Content-Type header is not correct (for example, the client attempts to send the request in XML, but the resource can only accept JSON).
500 Internal Server Error	The server encountered an unexpected condition that prevented it from fulfilling the request.
503 Service Unavailable	The server is unable to handle the request due to temporary overloading or maintenance of the server. The DCS Agent REST service is not currently running.
