Entering Facebook Username and Page ID
The Facebook Username will appear under the social section of the performer screen. It will link directly to the performer's Facebook page. The link is already formatted with "https://www.facebook.com/" so all you need to add is the page name.
You will also need to include the Facebook Page ID of the same facebook page. Without it, the link will not function properly. To get the Facebook Page ID, login to your facebook account, go to the page you wish to link and go to the About section. The page ID will be at the very bottom of the page under the "More Info" section. Only page admins and editors have access to the Page ID, so you will have to request them if you do not have a role for that page.
