“last\_updated” is not a valid Contact ordering property currently.

The list of valid values is available in the documentation: [Keap REST API](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
