A New ActiveMerchant Ebook

ActiveMerchant payment authorization diagram

[Via Ruby Inside] ActiveMerchant is a new PDF-format ebook covering the ActiveMerchant Ruby library for handling payments. It supports a number of payment gateways, including PayPal, Authorize.Net, and TrustCommerce. It’s a brief 74 pages long and sells for a dirt-cheap $9. I’m going to order myself a copy later today.
