Magento 2 - After Order Update

Question

Currently I have a plugin which has the following in the di.xml

<type name="Magento\Sales\Api\OrderRepositoryInterface">
    <plugin name="MyModule_OrderAfterSave" type="Company\MyModule\Plugin\OrderAfterSave" sortOrder="10" disabled="false" />
</type>

This enables me to call my custom class when an order is saved. However what I need to do is call my plugin any time an order is updated.

The reason for the question is that I have a payment gateway extension installed and it saves the order before taking payment and then updates the order based upon if payment was successful. So I need to call my plugin after the payment has been success or failed

Answer 1

If you want to call your class only when order payment is succeed or fail then it is not good to use your class on order save. If you will use this method then your class will always (i.e invoice save, shipment save, credit memo and many order save which you can do with order from back-end).

If you want to call your class on payment succeed or fail then you can use event sales_order_place_after event , this event will fire right after your payment.

As you can see \Magento\Sales\Model\Order class

public function place()
    {
        $this->_eventManager->dispatch('sales_order_place_before', ['order' => $this]);
        $this->_placePayment(); // this is the place where magento does the payment operation
        $this->_eventManager->dispatch('sales_order_place_after', ['order' => $this]);
        return $this;
    }

In this event you can get $order object like $order = $observer->getEvent()->getOrder();

Note: If you are using some 3rd party payment module then you need to confirm with this event because I had some experience with that this event is not executing only some 3rd party module
