Let’s say i have a Facebook page tab (iframe) app that i want to connect to multiple Facebook pages, so users can enter the app through more then 1 Facebook page. Now my question is; is there a way to see if they visited the page tab app through Facebook page A or through Facebook page B?
Thanks in advance.
