I have a Facebook app that users log in to with a mobile app, using a Facebook login button. That user ID, which is app-specific, is how we identify that user.

Is there a way to determine that app-specific user ID from messenger through a Facebook bot? I don't think there is, but if someone can think of a workaround, please let me know.
