This add-on extends XenForo 2 payment profile system to accept payment via Authorize.Net. It is the XF2 version of [bd] Paygate: AUTHORIZE.NET ARB.
Xfrocks has open sourced their Authorize.Net payment provider. As it appears he is leaving the Xenforo community, posting an updated version using an updated fork of the php-sdk from Authorize.net to bring support for PHP 8.2 and 8.3.
