The Authorize.net payment plugin has been updated by its developers to work on Phoca Cart 4 and Phoca 5.
It is a native written extension using new Joomla architecture which makes the plugin compatible with Joomla 4/5 and even further v.6.
It works fine with both Phoca Cart 4+ (Joomla 4) and Phoca Cart 5 (Joomla 5) and needs PHP ver.8.1 as a mininum requirement.
Authorize.net is a payment gateway service provider that allows businesses to accept and process a wide range of online payment methods.
As long as your business is based in the United States, Canada, Europe or Australia, you can accept international payments for anywhere in the world.
Here is the short video overview and you also can test how the plugin works on the demo site.
