get Facebook Group Id using identifier or url

Question

I would like to get a facebook group id by using a URL or specific identifier.

For ex: http://www.facebook.com/groups/chennaifoodies/ should give group

Answer 1

I don't think you can get the Group ID from the url you mentioned with the group username.

But, you surely can get the same with the url:

http://graph.facebook.com/search?q=chennaifoodies&type=group&access_token=ACCESS_TOKEN

Yes, you'll be needing an active user access token to query this.

Or, the graph API (the same thing)-

/search?q=chennaifoodies
