The code below works to mark an order as complete, but does not execute other actions as you describe in the admin

// create a new checkout instance and order id
$checkout = new WC_Checkout();
$this_order_id = $checkout->create_order();

$order = new WC_Order($this_order_id);
$order->update_status('completed');
