Google Friend Connect, the tool that allowed web developers to add social networking to any site, has launched API. Here's what site owners and developers can expect:
Plugin developers - Make plugins to integrate with popular content management systems, bulletin boards, or any open framework. To get you started, we have created open source plugin samples for WordPress, Drupal, and phpBB.
Gadget developers - Make OpenSocial applications with greater control over how data flows across servers with signed requests. Use server-side authentication mechanisms so that a site with Friend Connect can act as an OpenSocial container.
