Illustrative example: built from the service description (WSDL) in the same format as a real response, with made-up values. The Request block is shortened.

Errors

All errors come back with HTTP 200: check ResponseState, ErrorCode and Messages. The errors every operation can return (expired or invalid token, API not enabled, HTTPS required, general errors) are listed once in Responses and errors.

Errors specific to this operation:

ResponseState	ErrorCode	Message	What it means	What to do
Invalid	1000	Unable to find any tasks associate with project guid: {projectGuid}	The project loader returned no project.	Send the project GUID.
