Find your Facebook ID

To find your unique Facebook ID, you must first log into your profile to check your privacy settings so that search engines have access to your timeline.
This must be temporarily activated so that the service can find your ID.

Go back to your profile page and copy the URL you have in your browser, for example:
https://www.facebook.com/ola.nordmann.4

Open https://findmyfbid.com/  in your browser and paste the URL, then click the button
"Find numeric ID".

If you get the status "Success" you will see a string of numbers that is your unique Facebook ID.

In the control panel of your online store, navigate to Configuration > General and enter your Facebook ID in the Facebook Administrators field to enable Facebook comments to your online store.
