Deprecation Notice: Authorize.Net has deprecated the use of MD5 Hash. When configuring, enter a Signature Key using SHA-512. These instructions include the updated step. Payment processing will not complete until you add the correct Signature Key. For details, see Authorize.Net's MD5 Hash End of Life & Signature Key Replacement and What is a Signature Key. To install the patch, see the Magento KB article Update Authorize.Net Direct Post from MD5 to SHA-512.
