domain property
Required if allow_missing_ids is unset or false.
The client-defined scope or source of the service call, which typically is the domain on which the service has been implemented and is currently being run. For example, if the service is being run by client Foo, Inc., on job board www.foo.com and career site www.bar.com, then this field is set to "foo.com" for use on the job board, and "bar.com" for use on the career site. Note that any improvements to the model for a particular tenant site rely on this field being set correctly to a unique domain. The maximum number of allowed characters is 255.
