Where do I find the Facebook application id for the the fb_social module? I just installed the fb_social module. Now I need to set up the module which requires the Facebook application id. 

Under the field reads: Get the ID of your facebook app or create a new facebook app : here.

But the link drive me to the main page of my facebook account. 

Where is the right place to find it?
Login as FB app admin
Go here: https://developers.facebook.com/apps
Copy the destination for "Edit settings" link for your app
Take app ID from the URL. This is the pattern: https://developers.facebook.com/apps/[your app ID]/summary
