Can the shipping cost be changed?

Question

1C-Bitrix

Is it possible to reset the shipping cost in Bitrix by the OnSaleOrderBeforeSaved event?
setDeliveryPrice doesn't work.

Answer 1

You need to change not the shipping cost, but the shipping cost. Something like this:

$eventManager = \Bitrix\Main\EventManager::getInstance();
$eventManager->addEventHandler('sale', 'OnSaleOrderBeforeSaved', ['OrderEvents', 'onBeforeOrderSaveHandler']);

class OrderEvents {
  public static function onBeforeOrderSaveHandler(\Bitrix\Main\Event $event) {
    $order = $event->getParameter('ENTITY');
    $shipmentCollection = $order->getShipmentCollection();
    
    foreach($shipmentCollection as $shipment) {
      if(!$shipment->isSystem())
        $shipment->setBasePriceDelivery(0, false);
    }
  }
}

UPD
About if(!$shipment->isSystem()) I'm not sure, I took it from the sale.order.ajax component. I remember that there, like, two shipments are created - one system, but I don’t remember why.

Answer 2

The price does not change, so I already tried.
