List all contact is not working for order=last_updated

List all contact is not working for order=last_updated

“last_updated” is not a valid Contact ordering property currently.

The list of valid values is available in the documentation: https://developer.infusionsoft.com/docs/rest/#!/Contact/listContactsUsingGET

id, date_created, name, email

Thanks Tom, Do you have any idea, how can we get all contacts updated in last one hour using REST Api. Thanks
