I've set up authorize.net direct post in test mode on my live server.

Trying to make a purchase I get an error. In the exception log I get :

main.CRITICAL: The transaction was declined because the response hash validation failed. {"exception":"[object] (Magento\Framework\Exception\LocalizedException(code: 0): The transaction was declined because the response hash validation failed. at /var/www/html/vendor/magento/module-authorizenet/Model/Directpost.php:539)"} []

Does anyone know why this is occurring?

Any help would be appreciated.

Thanks.

The problem was that payment/authorizenet_directpost/trans_md5 configuration was NULL.

To fix this set an MD5-Hash in the Authorize.net merchant admin under Settings > Security Settings > General Security Settings > MD5-Hash.

Then enter that same value in the Magento Admin under Stores > Configuration > Sales > Payment Methods > Authorize.net Direct Post > Merchant MD5.

Authorize.net will stop supporting MD5 based hash usage on June 28, 2019. This will result in Magento merchants not being able to process payments using Authorize.Net Direct Post. To avoid this, merchants need to apply the patch provided by Magento and replace the existing MD5 hash with a Signature Key (SHA-512) in the Magento Admin configuration settings.

1º Method

You can upgrade to version 2.2.8 or 2.3.1

2º Method

You can apply this patch from Magento below. Don't copy the space in that your Authorize.net panel will show.
