Where can I find my Facebook application id and secret key?
In my Facebook account, where can I find these application IDs, secret key, all?
Solution 1:
You should use the Developer App.
On the right is a section titled "My Applications" from which you can select an application to see its information.
You can also go straight here as well, which will list your apps on the left.
Solution 2:
From 2018:
Go to Settings -> Basic -> App Secret
(type your password and you're ready to go).
