QR Code to Facebook Groups in the FB App

Does anyone know the url or how to create a QR code that leads users to a Facebook group through their mobile app? If there's a way to make them automatically join, even better.

I have found some info in regards to fan pages and auto liking, but not in regards to groups/joining. I tried to adapt what I found about page's but haven't had any luck yet.

There was a method posted here a few months back on how to make custom qr code and earn from it. I tried by searching but couldn't found. Any1 bookmarked it? It may help OP.

Thank you for the response - I searched before I posted but didn't have any luck either. I was able to figure it out. Just in case anyone else is looking for the solution, use the URL:

fb://profile/{group_id}

You can find the "group_id" by looking at the source code of the groups main page then control + f "group_id".

Finally found it. http://www.blackhatworld.com/blackh...deo-tutorial-create-sell-custom-qr-codes.html
