Item Description: AuthorizeNet backend for Business::OnlinePayment
I'm really just posting this in response to anyone searching for information on interfacing with Authorize.net. At last look, the only PerlMonks thread on the subject was Interfacing to Authorize.Net, which is basically a collection of makeshift solutions to a pretty common problem.
Anyway, Business::OnlinePayment::AuthorizeNet works really well (for now anyway, lets hope the maintainers keep it up!) and fellow monks should keep it in mind when pitching for an e-commerce job.
