Question: what is fb page id?
Answer: If you have a Facebook page with a URL like this: https://www.facebook.com/smashballoon then the Page ID is just smashballoon. ... If your page URL is structured like this: https://www.facebook.com/pages/smashballoon/123654123654123 then the Page ID is actually the number at the end, so in this case 123654123654123.
