问题
Okay, so I created a new account on Facebook but used the link that said 'Create a Page for a celebrity, band or business' I chose Brand or Product and signed up. Now it's absolutely impossible for me to get an API through my new Facebook account, there's no option to be seen to get the API key, in fact I spent half a day trying to figure out. I decided to log into my personal Facebook account and get an API key, managed to do it in 10 seconds flat, so why on earth is it so hard to get an API key if you've set up an account as a brand or product?

You have to use a personal account to create applications on Facebook. You'll also have to verify yourself as a developer using a mobile phone number or credit card.
These measures are in place so that facebook can identify the creator of applications as "real" people.
