To direct users to a specific URL after they log in with Facebook, you can use Facebook's API to add a redirect URI to your app settings.

Follow these steps:

1. Go to the Developer Dashboard and select your app.
2. Click on "Settings" in the left sidebar.
3. In the "Basic" tab, add the URL you want to redirect users to after they log in to the "Valid OAuth Redirect URIs" field.
4. Save your changes.

When a user logs in to your app with Facebook, they will be redirected to the URL you specified in your app settings.
