As I am still new to FB App development I was wondering how to implement such Apps: https://www.facebook.com/Texterclub/app/1002447493202906/ and https://www.facebook.com/Minikinder.Lieblingssachen/app/511509218944445/
Basically these Apps display HTML content inside an iframe but according to the actual Page (shop, business etc) that has it embedded. I have already made a Page Tab App however in my scenario it should load different html contents based on the Page it is embedded.
Hence, does anyone have experience or have hints on how to implement such apps? Is it possible to authenticate the user and based on his credentials return a corresponding html content? After making the App live, in which form will the user be able to install it?
