Finding your Facebook user ID used to be as simple as clicking on your profile picture and copying it out of the URL. Unfortunately this is no longer possible, but it is easy to find your user ID using the open graph API.
To find your user ID you first need to know your profile user name. If you don’t know this you can find it by clicking on ‘my account’ under the settings tab your user name is the second setting under your name.
To find your user ID just attach your user name to the end of the following URL:
https://graph.facebook.com/
EG:
https://graph.facebook.com/robert.went
This will then bring up your information like the image above where the first line gives you your ID. Check our social media management pages.
