facebook login for asp.net

Question

In one of the website I need login with facebook account. I am using following code on face book login button.

string callbackUrl = "https://www.facebook.com/connect/login_success.html";
        Response.Redirect(string.Format("https://graph.facebook.com/oauth/" +
          "authorize?client_id={0}&redirect_uri={1}&scope=offline_access," +
          "publish_stream,read_stream,publish_actions,manage_pages",
          1448xxxxxx781763, callbackUrl));

it shows 'Success' with access token url for a brief moment and then a security message appears and the access token is lost. How can I capture the access token? Thanks

Answer 1

Use your own domain for the callbackURL, not facebook.com.

That being said, you are better off by using the JavaScript SDK for login: https://developers.facebook.com/docs/reference/javascript/FB.login/v2.0

That way you don´t have to worry about the Access Token at all.
