Are multiple SITE URLs for a Facebook app possible?

Question

We have a software platform with Social Logins, and Facebook is one of them. However, from time to time we indicate our domain name to the client. e.g. client.isebox.net becomes isebox.clientdomain.com

The settings of the Facebook application allow, apparently, a finite (for example, ONE) number of website URLs, however, this allows the use of many APP DOMAINS.

We are trying to make use of our social login for all our customers without creating an application for each new domain.

Now I was able to “hack” the system by adding the client’s domain name to the “Mobile URL” ... since we are not using this field, it accepted the client’s domain name in the “Domains Application”, since we added it to the mobile URL field devices.

This is probably the wrong approach. In fact, of course. But it does work. However, this will not work for our next client, since there are no more URL fields available. :)

Does anyone have any tips on how our application should work and be configured if we use our application for different domain names?

Thanks, Community! Salvatore

Unfortunately, on September 30, 2011, the blog post was misleading. The relevant section is "Support for multiple domains in the application for developers." Reading this paragraph, it would seem that there are no restrictions as to which domains can be combined together in one application.

However, when I tried to add a second domain to an existing application, I received an error message stating that the new domain should be obtained from the site URL. One comment on this blog described a similar experience. And this limitation was confirmed by the answer to this comment of someone in the relations of developers on Facebook, explaining that "all application domains must be obtained from the site’s URL".

I believe the confusion is due to the incorrect wording of the entry itself, which says: "The URL of your applications (website and / or URL of the mobile website) must be obtained from one of the domains listed in the field "Domain Application".

* Update: To clarify what types of domains are allowed, let your website URL be "mywebsite.com". You will be allowed to add "mywebsite.co.uk" as an additional application domain, but you will not be allowed to add "myalternatewebsite.com".
