Is there a way to acknowledge orders into Veeqo?

Like we currently get the orders using api using since_id or update_date. Date gives all orders at a time if we fetch last one day orders. Since_id is not coming sequential, Some new orders
come later with smaller id then since_id. So suppose last since_id is 82095493
and we receive new order with this id : 82084563. So it gets missed as we always get the orders after last since id. So is there a way to acknowledge the orders and then fetch the orders which are not acknowledged in veeqo.
