I received an email from Facebook with the title “Upgrade Your App to OAuth 2.0 and HTTPS by October 1st.”

In summary, starting October 1, 2011, Facebook will require the use of “HTTPS + OAuth 2.0” for Facebook apps.

Here’s the email from Facebook:

---- Dear Developer of Your App,

Reminder: Upgrade Your App to OAuth 2.0 and HTTPS by October 1st. In May we announced that all apps on Facebook need to support OAuth 2.0 and HTTPS to make the platform more secure.

All apps, including page tab apps, must migrate to OAuth 2.0 for authentication. The old SDKs, including the old JavaScript SDK (FeatureLoader.js) and old iOS SDK (facebook-iphone-sdk) will no longer work. In addition, iframe Canvas and Page Tab apps must support HTTPS and provide a secure canvas or secure page tab URL.

If you haven’t already made these changes, visit the Developer Roadmap before October 1st for more information about how to upgrade your app and avoid having it disabled.

You can also seek support in the Facebook Developer Group: https://www.facebook.com/groups/fbdevelopers/

Thank You, Facebook Developer Relations

　

That’s all from the Gemba.
