This is required. Please let us know if you do not have a Facebook Manager Business ID set up so we can help get this setup. If you do not have a FB manager ID set up please note: you will need to create a FB business manager per their T.O.S. You can do that by going to business.facebook.com
and creating a business manager. There we will need the 15 -20 digit code that can be found in the manager's URL. An example is: https://business.facebook.com/home/accounts?business_id=153859771900000
. Where it says "business_id=" that's the number we need.
