One Facebook app for each domain and request_uri

Question

I'm developing a facebook-integration wrapper on top of Facebook PHP SDK. My app is kinda a backend for a product store. Many backends on different domains of course.

Since the initial request for access token require the request_uri param (that should match that in the app setting) should i create one facebook app for each backend?

request_uri = http://mydomain.com/admin/social/facebook_thanks.php

(this is the same as defined in application setting). If i add another domain (say: "anotherdomain.com") should request_uri be changed to this?

request_uri = http://anotherdomain.com/admin/social/facebook_thanks.php

Answer 1

Facebook will only redirect users to the domain set in your application settings, no matter what you change the request_uri to.
