Hi, I'm interested in possibly using E-Junkie for a small business but am not sure if it can handle my needs. What I am looking for is someone to be able to buy "virtual credits" from my site (those credits are used to purchase specific services and are handled on the site). After purchasing, there would need to be some way to automatically notify my site of the purchase and to increase the user's "credits" in the database.
Is it possible with Ejunkie and how hard would it be? I've looked at the Paypal and Google Checkout API but it is pretty confusing. The programming language used is Ruby on Rails.
