Magento_SalesRule there are two events,
<event name="sales_order_place_after"> <observer name="salesrule" instance="Magento\SalesRule\Observer\SalesOrderAfterPlaceObserver" /> </event> <event name="sales_model_service_quote_submit_before"> <observer name="salesrule" instance="Magento\SalesRule\Observer\AddSalesRuleNameToOrderObserver" /> </event>
but none looks like the one i need. I needed the same for when adding a coupon but i managed to do something if "pluggin in" the
canProcessRule method of
Magento\SalesRule\Model\Utility but i cant find something similar for when the coupon is removed
Theese operations like add and remove a coupon are made only in JS? There is a controller that process this?
checkout_index_index.xml layout it pass an item argument
Magento_SalesRule/js/view/payment/discount which then loads theese two js
That by the name itself looks pretty straightforward, one to add and one to remove the coupon
In the cancel-coupon JS doing a console.log to url return:
This is using rest web services? (Kind of same url for when adding a coupon)
There is a way to know when a coupon is removed from the quote/cart?
