I have looked all over the internet. Can anyone point me to some resources for adding the "Add to my page" button on my facebook pages tab app. I have seen other pages do it, so i know its possible.
You can add an app to a page via:
Create a link on your site to:
https://www.facebook.com/dialog/pagetab?app_id=YOUR_APP_ID&display=popup&next=URL_TO_REDIRECT_USER_TO_AFTER_ADDING
You can also trigger this using the Facebook Javascript SDK (details on the doc above)
