[bop-devel] Need help implementing Authorize.net's Direct Post Method

[Bob McClure Jr]

My client has been using Business::OnlinePayment::AuthorizeNet for
some time to handle Auth.net's AIM process.  Now they want to change
to their Direct Post Method to get out from under some PCI
requirements.

In this process, the form, including a callback URL on your server, is
sent directly to Auth.net.  They process the CC info and return a
response to your server.  Your server then, depending on approval,
returns a redirect URL, e.g. to the thank you page on your server, to
Auth.net, which they send to the user.

Auth.net has no Perl support, AFAIK.  Has anyone invented this wheel
or can give me some tips for using/hacking an existing module to
handle this?

For another client, I've built a plain Perl handler for PayPal's
Instant Payment Notification, but it's an asynchronous process, while
Auth.net is synchronous.  That is to say, the transaction is "thrown
over the wall" and the response is handled independent of the user's
activity.

Hints and clues are welcome.

Cheers,
