in reply to Credit card processing provider and Perl interface

I use PayPal. They allow people to pay with credit card, even if they don't have a paypal account. They have a well documented API, and the Instant Payment Notification system (IPN) helps automate transactions. There are some paypal related modules on CPAN - even if you don't choose to use them 'as is', you can use them as examples when writing your own code.

    Am I right that for using PayPal I need first to subscribe to their "Website Payments Pro" package which is $30/month. Then I can start using it right away, say with Business::PayPal?
    If you could share with me which module you use I would appreciate.
      I'm using "Website Payments Standard" - it's free. And I use a slightly modified version of Business::PayPal. But I would recommend using that as a starting point, and customize only if necessary.
        But Website Payments Standard does not send a confirmation response, it just sends an e-mail as far as I understand. So how to automatically process the payment for the customer? Could you clarify, please.
