I have a custom controller where i apply coupon code discount like this:
$this->checkoutSession->getQuote()->setCouponCode($discount) ->collectTotals() ->save();
Now, like magento 2 default does, I want to be able to remove that coupon code discount.
So i created a custom controller and i want to remove here the discount:
the only thing i found to remove the coupon discount is this:
$couponCode = $this->getRequest()->getParam('remove') == 1 ? '' : trim($this->getRequest()->getParam('coupon_code'));
But this dosen't work for me.
Does anyone know what it's the right way to remove this discounts in my controller?
