Sugar Market APIs - Date filtering options for Opportunities

Does the 'Get Opportunities' endpoint from Sugar Market APIs, ref link: SugarMarket RESTFUL API (sugarcrm.com) support filtering records by updated date? When I was testing out the endpoint, 'date_field = created_date' works fine but 'date_field = updated_date' does not. I am able to retrieve newly created records but not newly updated ones. Any solution on how I can retrieve newly upated records as well?
