I thought I would share this nugget of information with the development community.
I tried to register an application with Facebook after their recent changes. The API key was missing… or so I thought. The only mention to an API was the Graph API Explorer, which is not what I was looking for.
I was perplexed. It was there the last last time I setup an app (which admittedly might have been a few weeks ago). What the heck?!?!
So I did what any other developer does when stumped, I Googled it! Turns out that as part of the recent changed they combined the API Key and their App ID. So if you need the API key, use the Facebook App ID.
It would have been nice for them to make that a bit more easier to determine, but I digress.
