How Do I Check Whenever A User Get A Badge?

In order to do that, you would need to have some code placed in all places where you are giving the user the badge, as there is no native way to do it (I think).

I would recommend that you utilise a BindableEvent, which is fired any time you fire the award badge function (so add a couple of lines of code near the award badge thing, to fire the event), then you can listen to that event from another location and do what you want from there
