At Facebook's core is the social graph; people and the connections they have to everything they care about. Historically, Facebook has managed this graph and has expanded it over time as we launch new products (photos, places, etc.). In 2010, we extended the social graph, via the Open Graph protocol, to include websites and pages that people liked throughout the web. We are now extending the Open Graph to include other actions and objects created by apps and enabling these apps to integrate deeply into the Facebook experience. This “How-To” video walks you through our tutorial showing you step-by-step how to build an Open Graph app that allows users to publish stories about cooking recipes.

We are hosting our fourth f8 conference today in San Francisco, where we’re introducing the the next evolution of Facebook Platform and the Open Graph.

Today we are launching a redesign of Platform Status to make it easier for you to see the current status, issue history, and API health of our Platform.

Subscribing to threads in Comment Box; Like Story Dashboard; API access to Send button metrics; Reference Documentation.

One of the most frequently asked for "How-To" requests from developers is how to handle invalid access tokens. Access tokens for users can become invalid due to various reasons. In most cases, they can expire if it’s past the time specified by ‘expires’ field (by default access token have a 2 hour lifetime). What many developers do not realize is that an access token can also expire if a user changes her password, logs out or if she de-authorizes the app via the App Dashboard. It is very important that your apps handle such situations. If your access token expires, you need to reacquire a valid access token.

Earlier this week, we updated our Developer Roadmap to require the use of OAuth 2.0 and HTTPS. These updates are part of a continual process to make our Platform more secure for developers and users. Over the past few days, we received several questions from developers about these updates. We wanted to provide more context around why we are requiring these changes and how we can work together to provide a safer online experience.

As part of our continuing series of “how tos,” we thought it’d be interesting to show how you can easily upload photos to a user’s profile.
