Magento – Magento 2.1 braintree credit card error handling

magento2payment-gateway

In Magento 2, I am using brain-tree credit card payment method on live site. Sometimes it shows error,
unable to place an order, please try after sometimes
but I want to know exact error on front end side about that transaction declined. I want error handling for Braintree credit card payment so that it makes easy to know the reason behind failed payment.

As far as I know, Magento 2 use Ajax to handle this task.

We should take a look at file:

vendor/magento/module-checkout/view/frontend/web/js/model/place-order.js

      return storage.post(
            serviceUrl, JSON.stringify(payload)
        ).fail(
            function (response) {
                errorProcessor.process(response, messageContainer);
                fullScreenLoader.stopLoader();
            }
        );

So, we need to override this file or the errorProcessor.process() - vendor/magento/module-checkout/view/frontend/web/js/model/error-processor.js handler. We can alert the error message.

Magento – Authorize.net Direct Post hash validation failed

As defined in app/code/core/Mage/Authorizenet/Model/Directpost.php, this exception is thrown if any portion of the below evaluates as false:

if (!$this->getConfigData('trans_md5') || !$this->getConfigData('login') ||
    !$response->isValidHash($this->getConfigData('trans_md5'), $this->getConfigData('login'))
) {
    Mage::throwException(
        Mage::helper('authorizenet')->__('Response hash validation failed. Transaction declined.')
    );
}

So, it's one of three things:

You have no trans_md5 defined in the config tree payment/authorizenet_directpost/trans_md5
There is no login defined in payment/authorizenet_directpost/login
The method isValidHash is returning false

The method isValidHash returns false because there is an issue with either the generated hash (e.g. your API Login/Key are wrong, generate a new one and re-enter) or the amount of the transaction somehow differs between Authorize and your system.

The latter is less likely, but because generateHash in Mage_Authorizenet_Model_Directpost_Response uses the transaction amount as part of the hash, it's a potential factor here.
