What block creates an order in Magento2? Basically I need a plugin or observer to make an api call right after the order is created.
I have made one extension and used below events with order event.
app/code/Magento/Checkout/Controller/Onepage/SaveOrder.php checkout_controller_onepage_saveOrder app/code/Magento/Checkout/Controller/Onepage/Success.php checkout_onepage_controller_success_action
Let me know you are searching for the same or anything else. Good Luck!!
