JavaScript SDK

The JavaScript SDK enables you to access all of the features of the Graph API via JavaScript, and it provides a rich set of client-side functionality for authentication and sharing. The JavaScript SDK is also necessary to use the XFBML versions of the Social Plugins. Many functions in the JavaScript SDK require an application ID. You can get an app ID by registering your application.
For example usage, check out Facebook for Websites and the Authentication guide. We also have a JS Test Console which allows you to test and debug common JS SDK methods.

Open Graph protocol


The Open Graph protocol enables you to integrate your Web pages into the social graph. It is currently designed for Web pages representing profiles of real-world things — things like movies, sports teams, celebrities, and restaurants. Including Open Graph tags on your Web page, makes your page equivalent to a Facebook Page. This means when a user clicks a Like button on your page, a connection is made between your page and the user. Your page will appear in the "Likes and Interests" section of the user's profile, and you have the ability to publish updates to the user. Your page will show up in same places that Facebook pages show up around the site (e.g. search), and you can target ads to people who like your content. The structured data you provide via the Open Graph Protocol defines how your page will be represented on Facebook.
