-- Gets all of the variables or the specific variable. This is a paginated
-- API. Providing null @maxSizePerPage@ results in retrieving maximum of
-- 100 records per page. If you provide @maxSizePerPage@ the value must be
-- between 50 and 100. To get the next page result, a provide a pagination
-- token from @GetVariablesResult@ as part of your request. Null pagination
-- token fetches the records from the beginning.
