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.
Due to sudden changes made by Facebook on April 4th, 2018, it is unfortunately no longer possible to display content from a Facebook Group. We apologize for any inconvenience this may have caused.
If you have any trouble figuring out your Page ID then just shoot us a message and we’ll help you out.
