Magento 2.4.6 Braintree Custom Discount not added in Total and customer charged total amount

rahuldambare commented 1 day ago

Summary

I am working on custom discount for Magento using this blog https://meetanshi.com/blog/add-custom-discount-in-magento-2/, but it is not adding that custom discount while sending request to payment Braintree Request not adding custom discount and customer charged full amount .

For Paypal I have made adjustment as per https://github.com/magento/magento2/issues/5735 , which is working fine . module-paypal/Model/Apiu/Nvp.php function callSetExpressCheckout at Line 812 add before "$response = $this->call(self::SET_EXPRESS_CHECKOUT, $request);" this snipped: $request['ITEMAMT'] = $request['AMT'] - $request['TAXAMT'] - $request['SHIPPINGAMT'];

Only facing issue with Braintree payment where custom discount is applied .

Magento version 2.4.6p3 PHP 8

Proposed solution

Custom Discount should add in braintree request or in discount field for Braintree request and final total should be minus of that discount

I have one observer which add this custom amount item in cart, I think that is not working for magento 2.4.6

<event name="payment_cart_collect_items_and_amounts">
            <observer name="paymentfee" instance="MyModule\CoreCredit\Observer\AddCustomAmountItem" />
        </event>


public function execute(Observer $observer)
    {
        /** @var \Magento\Payment\Model\Cart $cart */
        $cart = $observer->getEvent()->getCart();
        $customAmount = -(float)$this->helper->calculateCreditbalance();

        \Magento\Framework\App\ObjectManager::getInstance()->get('Psr\Log\LoggerInterface')->debug('@@@ >>> Payment Check PartSimple\CoreCredit\Plugin >>>  ' .  $customAmount); 

        $cart->addCustomItem(__('Credit Amount'), 1, $customAmount, 'creditamount');
    }
