I’m building a website that makes use of Facebook connect. I’m authenticating users client-side with the javascript SDK and calling an AJAX method on my server every time a user logs in to check if the user is known to my app, and if the user is new to store their FBID in my database to register them as a new user.

My question is: Can the access token returned by Facebook to the Javascript SDK be used server-side (with the PHP SDK for example)? Can I send the access token string to the server via an AJAX call, store it in my database (along with a timestamp so I know how long it’s valid for) and then use it to make calls to the graph API server-side? Is this even a logical thing to do?

    Yes, this should work. Look at this question: How to properly handle session and access token with Facebook PHP SDK 3.0?

    This is a workaround for the old JS and new PHP SDK. In my app I send the access token generated by the JS SDK via a form to my PHP. I have no doubts that this also works by sending the access token via ajax!
