I try to take the final product list after the checkout, so I create an observer for that. I found a list of all dispatched events in Magento 2.1 which looks like this:
I tried a lot of events, which is work properly, but nothing seems to work for the final checkout button.
I also tried
checkout_cart_save_after but this event is before the final checkout button, and
checkout_type_onepage_save_order_afterbut this event is not working.
Does anyone know how to solve this problem? Or which event is responsible for this?
