Three weeks ago, we launched the OAuth API as, "The easiest way to make authenticated calls to the Twitter and Salesforce REST APIs."
We've always believed that APIs are better together, so today, we're rolling out support for Facebook, Flickr, and Foursquare. Not only is it now easy to get started with one API, supporting multiple services in your application is practically trivial.
Now you can make an authenticated request in a matter of minutes starting from developer.apigee.com, without writing a single line of code, for example:
Want to build apps for iPhones, iPods, iPads, or Macs? We've also added a new client library in Objective C to make working with the OAuth API on iOS and OSX even easier!
