so I've been looking to do some adjustments with an observer by listening to the event that is fired after a user successfully places an order, whether in the backend or the frontend. But, I don't know which event I'm looking for. My best guesses are:

  1. checkout_submit_all_after
  2. checkout_controller_onepage_saveOrder I got the above events from This list of Magento 2 events

Can someone help me understand which event I need? and which of the ones I provided, if any,is correct and why? and what's the difference between both?

Below is the sample code of the and event which is trigered when order is placed. events.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
    <event name="sales_order_place_after">
        <observer name="my_event_name" instance="Foo\Bar\Observer\MyObserver" />


namespace Foo\Bar\Observer;

use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;

class MyObserver implements ObserverInterface
    public function execute(Observer $observer)
        /** @var $orderInstance Order */
        $order = $observer->getOrder();
        $orderId = $order->getRealOrderId();

  • I adjusted my question. I noticed that I wasn't being very clear about which event I wanted. And I was confused about only one thing in your code which is "/** \@var $orderInstance Order **/" can you tell me which class I need to import so that I can check its methods.

sales_order_place_after is fire when place() of order object is called and in magento every payment does not call place() when order placed.



Is only called when customer has been redirect to checout/onepage/success. Also this event only called whenever order place from frontend and customer visit checout/onepage/success.

MY suggestion, this two event not proper,We should be use checkout_submit_all_after this event is fire when order place from frontend and backend.

it is fire immediate order place
