I've built a tiny FB app whose purpose is to get the user's public profile URL. I have used the client-side authentication example provided, and it works just fine. I have also setup an application on Facebook.com so I can provide an APP ID. For this use, I have left App Domains blank, and made the app the type "Website with Facebook Login". And then I supply the "Site URL", the callback.
My trouble is that my web application runs across multiple domains. Individual customers have their own unique subdomain on our main domain. Do I have to create a new application for every single subdomain? It appears that way now, which would lead to hundreds — possibly thousands — of applications just to get a working callback URL for every customer domain.
Is there an easier way to do this?
For this use, I have left App Domains blank
You might want to reconsider that; especially you might want to read the explanation text for “App Domain” parameter that hovering over the [?] shows …

I have more than few clients that would like to add facebook connect to their landing pages (managed by me). They are too many and not enough tech-savvy to manually create ad appid for each of them.
So my only solution is to usa my own appid to add facebook connect to all my clients websites, but as far as I know, Facebook doesn't allow to simply use the same appid on any domain.
How can I solve this? I can't find any documentation to solve my issue. Does anyone have a direction for me?
This has been discussed a couple o’ times before already – but I mostly commented on earlier questions, so let me write the whole thing up as a proper answer, for future reference.
[paraphrased] Multiple-client Facebook login via one single app id
Does anyone have a direction for me?
You probably rather don’t want to do that.
It is not really possible to run one simple app one multiple different domains.
As a workaround for only a few domains, people used to specify different domains for the different platforms – Website, Page Tab or Canvas App, plus Mobile alternative for Canvas – without actually using any of those platforms besides Website, which made the app usable on multiple domains as a website app. But since Facebook introduced their login/permission review process¹, you can’t do that any more – they expect you to present actual functionality on all platforms you have configured in your app.
You can kind-off use one single app for login on multiple domains – if you are willing to use only the server-side login flow, and to redirect users to one “main” domain (that gets specified as the app domain in the app settings) to login, and then from there back to the origin domain.
But this has several drawbacks:
It’s not what you’d call a “white label” solution. If your clients expect it to look as if users where logging in via “their” app, it should stay on their domain. Individual branding, in regard to stuff such as app name, app logo that shows in the login dialog, etc., would also not be possible. Additionally, app attribution – the link that shows up under content shared/posted via the app – would only link users back to the main domain, and not to your customer’s.
You would not be able to use the JS SDK for client-side API requests, or even just to embed it to render any of the FB social plugins that require an app id – the SDK checks what domain it is “running on”, and can not be tricked to accept a domain that is not specified in the app settings.
There could be privacy issues. An over-exaggerated example: Just because I as the app user decided to share my photos or videos I have on Facebook with your customer Our-Holy-Mother-of-Christ-Bakery.com, does not necessarily mean I want to share them with your other customer, amateurs-doing-all-kinds-of-nasty-stuff.xxx as well – but if they shared an app id for login purposes, I automatically would. Have fun writin’ the Privacy Policy (which is mandatory if you use FB login functionality, and FB also automatically checks if your app has got one) for that scenario ;-)
Finally, and most importantly: All your customers would be “sitting in the same boat.” If one of them, or in turn their website users, would publish spam via your app id, so that Facebook blocks it, login would not work any more for all of your customer’s websites. And if you decide only then, that setting up an individual app for each of your customers would be the better way to go, they would not be able to recognize their existing users any more, because of user ids being app-scoped since API v2.0 was introduced – so if users logged into this new app, that app would see a totally different user id. (And to rely on an email address as an identifier is risky, too, because you will not get one from the API for every user; for example if they registered using their mobile device.)
Edit: Plus, app/domain insights, as luschn mentioned in his answer.
¹ Yes, the review process has made it more laborious to set up multiple apps for multiple clients. But for apps that do the same stuff/use the same permissions in the same manner, you can refer to an earlier successfully reviewed app id to speed up the process a little. Also, screenshots of how f.e. posts made via the app look on timeline, and what UI components are used, as well as screencasts that you include in your submission could probably be used with little to no alteration.
Apps are not meant be used on several different domains, you will have to create a new App for each domain, i´m afraid. You can use the different platforms in the App settings to use different domains, but there are only a few so it´s pointless. Just create some screenshots and a tutorial for your clients, that´s how it is usually done.
Btw, it would be weird to authorize an App on a website, and the same App would allow you to be authorized on all other client websites. Also, insights are per App, so your clients may want to see their own insights and not the global insights of all domains together.
Many is not defined but i think for being a smart developer you need to create new app_ids for every project you need to use facebook connect. Just my opinion. It also allows you to monitor alot of stuff.
We have a software platform with Social Logins, and Facebook is one of them. However, we at times whitel-label our domain name to the client. e.g. client.isebox.net becomes isebox.clientdomain.com
The Facebook App settings allow for, what seems, a finite (e.g. ONE) number of Site URLs - however it allows for many APP DOMAINS.
We're trying to achieve using our platform social login across all our clients without creating an appID for each new domain.
For now, I've been able to "hack" the system by adding the clients domain name into "Mobile URL"... since we don't use this field, it has accepted the clients domain name in "App Domains" since we've added it to the Mobile URL field.
This is likely an incorrect approach. In fact, certainly is. But it works. However it will not work for our next client, as there are no more URL fields available. :)
Does anyone have any tips for how our App should work and be configured if we are using our application across various domain names?
Thanks, Community!

I have a Facebook app. This app is a "Website with Facebook Login". However, I need to use it across several URLs. One for development, one for testing, and one for production. My urls looks like this:
Dev - http://localhost:[dynamicPortNumber]
Test - http://mysite.azurewebsites.net
Prod - http://www.mysite.com
Unfortunately, I cannot figure out how to allow multiple URLs to be associated with this app so that I can do end-to-end testing. Can someone please explain to me how to do this?
If you are using multiple top-level domains, the only way to handle this would be to create new App IDs for each instance (dev / test / prod).
However, if you have the freedom, using multiple subdomains in the same top-level domain will get you the result you are looking for. For example:
Dev: dev.mysite.com
Test: test.mysite.com
Prod: www.mysite.com
This will allow you to use the same Facebook App ID across all domains, as long as you use "mysite.com" as the App Domain.
Don't forget to add your site's URL in the "Site URL" box in the "website with facebook login" section!
NOTE: I have, in the past, had to add each individual subdomain in the app domain box in an app for it to function properly, but usually it's because I've made an error somewhere else.
Sadly there is no way to deal with the issue of different URLs for development, testing and production using a single Facebook App ID, you will have to create 3 different App IDs for each of the cases and use them at different places.
You can also check out Getting Started with Your Facebook App on Heroku that does the same.
We have a browser based game which uses Facebook Connect through an AppID that we used to run the same game in a canvas until Fb Credits were introduced and we were forced to shut it down. Now, we only use the App the same way as a product page with the FbConnect integration on our own site.
Today's mail states for our case:
If your Connect app is accessing user connections or asking for additional permissions beyond age, email, and our Publishing Permissions, please remove these requests.
(This refers to this policy change: https://developers.facebook.com/blog/post/2012/09/05/platform-updates--operation-developer-love/)
We are using oauth FbConnect with scope=email,user_birthday. This is exactly what was specified in an earlier mail so it should be ok.
Once the user is authenticated, we simply call
https://graph.facebook.com/me?access_token=...
and read what comes there.
Is it possible, that we are not allowed to call the GraphAPI's me anymore? It contains info like gender, location and locale...
The Oauth data contains the fbuid, first/lastname and the email, but it does not contain the age, what we are supposed to be allowed to ask?
Do I have to call https://graph.facebook.com/me?fields=birthday explicitly?
Did anyone actually succeed in getting an "desktop web game hosted primarily off Facebook" to comply with their new policy without creating a new AppID?
Note: There have been a couple of questions about the "Sep 5th policy change" like Facebook: Notice of Violation this one and many previous closed as duplicates, but none I found so far contains questions or answers on a technical level.
Maybe you could skip the "Website with Facebook Login" part in developer settings and only provide your game directly via canvas. (eg. apps.facebook.com/logogame). that's what "on facebook.com" is all about, I guess.
Background:
I am working on a legacy ASP.NET 3.5 Web Forms applications. The application allows users to buy a subscription to a 'white-label' website which is generated for them and they can customize it further. It uses forms authentication.
A typical use-case is that the user creates an account on our system, purchases a website, and then proceeds to customize their website. The URL they will use to edit their purchased website is something like this: https://www.example.com/EditWebsite.aspx. There are many other pages also within our website editing toolbox with other URLs.
Problem:
My team has now been tasked with allowing people to use one account to access multiple website subscriptions. This means that one authenticated user could be trying to access one of many websites to edit if they use the URL mentioned above. Our system can be made aware of multiple subscriptionIds per User but the website editor web app only has support for one subscription.
To clarify with a simpler example: this would be like if Google all of a sudden allowed you to view two different inboxes with one GMail account. How would the system know which one you were trying to access if the URLs were the same for both?
We originally wanted to change the application to use URLs like: https://www.example.com/[subID]/EditWebsite.aspx which would give us all the information we need to send the user to the correct website. We looked into URL Routing to accomplish this but it seems that we would have to change all of the web app's internal links to use the route config to generate the correct URLs. Maybe we have the wrong idea here but it seems like too much work for a legacy application.
Another potential solution we came up with was simply using our systems' control panel web app (where they click links to edit any of their websites) to set a session cookie which our edit website web app can read to know which website to bring up. This has the disadvantage that the pages would not be bookmark-able and you could not look at multiple websites at once in different tabs of the same browser.
Question(s):
Is there any other options we have not investigated or thought of? Is there any other web sites which allow for this kind of behavior; how do they handle it? Is URL Routing the right way to do this and we just need to take the plunge?
Any input is appreciated!
The solution we ended up using was adding a URL parameter to the link which specifies which website you are trying to edit.
https://www.example.com/EditWebsite.aspx?subID=123
This parameter is included in the links to 'Edit Website' from the page which lists all of a user's websites.
When present, this sets a session cookie for the user. If the request parameter is not present, the app looks for the cookie being set; this handles all the internal links within the application. if a cookie doesn't exist and the request parameter was not set, we just pick the authenticated user's first subscription from the list.
This isn't perfect but it has worked without issue so far. The only consequence it has caused is that a user cannot edit multiple websites in the same browser session, e.g. using multiple tabs. This hasn't resulted in any support issues yet though so it is pretty much a non-issue.
