I’m using the FB Javascript SDK, and handling login via a custom button that calls FB.login. Ideally, I’d like to be able to record some tracking data whenever a user is shown the app approval/permissions dialog so that I can see how many users bomb out at this stage. Unfortunately, I can’t seem to find a reliable way of achieving this.
If the user is already logged in to FB, I can infer whether it will be shown by checking the login status before calling FB.login. If the user is not_authorized, then I know the permissions dialog will be shown. But if the user is not logged in, my information is more limited. I can assume that the user was shown the dialog if they finish the process as not_authorized, but if they end up being connected then I have no way of distinguishing between a user who was already connected and one who just gave approval.
I’d hoped that the auth.prompt event might help, but it doesn’t seem to be fired for the sequence starting from FB.login. Any suggestions?
Look at your app insights, there you’ll see Auth Dialog Conversions.
No need for own tracking for that.
