Publishing to facebook from different websites using one APP ID

Question

Hi,

I'm building a custom CMS for my clients and i've implemented the Facebook API for posting on Page Walls as admin. All works well but I do have one question. Let's say the FB app name is 'CMS FB APP'.

The CMS will reside on my clients' servers, is it possible to use 'CMS FB APP' for all of my clients? Or do I have to create an application for each CMS that I install on every different server?

In the app settings I have to set a Site URL and Site Domain but this is for each client different, I don't seem to find a solution for this problem.

Thanks for your respond

Regards

If you are using authentication, you have to create a separate app for each url where your app will be hosted. You will receive an error when the user tries to log in with facebook. Facebook requires that your 'next' and 'cancel' urls in the authentication return urls be on the same domain as your app's Site Url. One solution would be to setup an app with a base url such as example.com and have each client on their own subdomain like client1.example.com, client2.example.com, etc. Short of that, you are stuck making separate apps.
