mojoPortal content management system has the re-usable features of ecommerce built into the core so that they don't have to be re-implemented in each commerce enabled feature. The configuration settings in this article apply to all commerce enabled features. Currently mojoPortal supports accepting payments using Authorize.NET, PayPal, and Google Checkout.
Commerce Configuration is set at the site level so it is possible in some cases to have a single installation with more than one commerce enabled site, but there are limitations and this is not recommended. We recommend that if you are going to be doing ecommerce with your site, you make it a single site installation. Its important in most cases to have an SSL certificate installed on your site to do ecommerce though in some cases its possible to accept PayPal without having SSL on your site, it is not recommended.
