The parameter returnkey specifies the field to be returned in the response in order to be able to programmatically identify the resulting object. It is possible to use more return keys separated by semicolon ';'.
Note: It's necessary to use the technical field name (not the alias name specified in the ArcMap document or in the geodatabase). See ‘keyname’ for details. This key is implicitly used by WebOffice map widget and does not need to be passed by the 3rd party application.
