API via curl not populating fields

When I create a ticket with the curl command curl -X POST http://<DOMAIN>/sdpapi/request --data OPERATION_NAME=ADD_REQUEST --data TECHNICIAN_KEY=<TECH_KEY> --data-urlencode INPUT_DATA@new_request.xml the request ticket is created but the only field that is populated is the Technician. None of the other fields are being populated. Is there a problem with the XML?
