I am using RPXnow.com authentication solution for a rails app and am now at the point of wanting to develop Facebook integration features using Facebook Connect and the client api. What I am unclear on from RPXnow docs is the level of integration their solution provides. When a user connects via rpx using their FB creds, are they now using Facebook Connect? Can I make calls to the client api from my app? Do I need to use the RPX api to access the FB client APIs?
Anyone with experience using both who can shed light here, much appreciated.
dnewman,
Great question. Facebook Connect is simply a javascript layer built on top of the Facebook Platform APIs. RPX uses the platform APIs to authenticate the user, and after they have signed in, you may safely use the native Facebook Connect javascript to implement FB specific features on your site like posting activity back to the News Feed. You just need to set your connect URL on the facebook developer site and drop in the Facebook Connect javascript and then start implementing. After authenticating via RPX, the user will already have approved and "connected" to your website, and you'll have access to the breadth of Connect directly.
Also, if you have an RPX Plus/Pro account you can make simple RPX API calls to set a user's status and post activity on Facebook (and Twitter/MySpace).
