facebook javascript v2.0 -


Facebook Javascript v2.0 app notifies specific user IDs
But what if any old user has a Uninstalled the application and then changed that application after the version of the application?

Will they have the new userid ?

He will get the same ID, so that you can still identify the returning users. I tested it with an app to make sure: Authorize user, call / me, delete the app, authorize user again, call me / me & gt; Same id

EDIT: We have only discussed this in another thread:

It seems that Scoped ID can change if the user has unauthorized your app and long Authorized, but you have to delete the user data anyway, if the user does not use the app for a long time - data privacy and accessories
