I have a facebook Canvas App. Once the User authorizes the app, I am storing the facebook user name.

I want to collect more info about the user. I read the following posts.

Facebook Canvas App – Finding all users who have installed the app

How to get all the user IDs of people who are using your Facebook application

Once I store the username, if I want additional information how do I get it. Like Email, location and so on(assuming the app had extended permissions). Can I get these any time once I have the User name and App Access token?

Answer 1

So long as you have the user’s username or id and a valid access_token for that user with the required permissions, you can query this information at any time.

You should store both the username and the access_token to make this work.

Keep in mind that some of this information is available without an access_token. On the flip side, users can restrict their privacy settings so some of these items will not be visible to your app.
