How can I create two different isntance of connection to Facebook? - facebook

I need to have two different Facebook connection on the same website! So, they points to two different Application Keys.
How can I manage this?

This isn't something Facebook JavaScript SDK supports and this can't be simply achieved by storing FB object in other variable before adding another instance of SDK.
In the code of SDK FB is used directly pretty everywhere, and the response from API will use it too.
BTW, Even if it was possible your users would be needed to Authorize two applications if you want to access their data (transfer of data from one application to another violate platform policies).

As #JuicyScripter wrote, the js sdk itself can not be shared among different apps in the same document, and that's exactly what you can try to play with.
How about adding an iframe per fb app?
You have the main page (the +1) which acts as usual, then you load an iframe inside of it and in it you can load another fb sdk for a different application.
Depending on what exactly you plan on doing, you might need to communicate between iframes, which will only work if they share the same domain.
Another approach is to make all api requests from the server side, but you'll have to have an access token for the user per app.

Facebook connect service for my customers without appid

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.

Creating a Facebook comment box for different sites

I want to add the facebook comment box to several websites for different people. IT asks for an Appid which at first I thought meant their Facebook Business page id. Now im realizing that I need to create a Facebook App for this. My question is this, can I create one app, take the ID and use that for several different comment boxes on various sites that are not related and owned by different clients? Or should I make new Apps for each one?
Thanks
The comment boxes are separated by the URL you define in the HTML attributes, so technically you can use the same App ID for multiple clients since the pages have different URLs.
Still - I would advise you to create a new application for each client. At some point one client might ask you to give them admin access to the Facebook application - and you don't want to give one client access to the application that also serves your other clients...

How to register a Facebook Application dynamically via Graph API like wildfireapp and others doing?

I am trying to create a sweepstakes application.
I am trying to copy wildfire.
But I am unable to create facebook applications dynamically like they are doing.
I checked it they are using graph api to show on front end but there is no method available in graph api to create applications dynamically.
Can anyone please guide me how wildfire is doing dynamic app creation. Is there any alternative available?
In general, they are likely not creating new applications for each client. Unless you can show us evidence of this, it is the same application being installed many times onto their client's Facebook Pages.
The application script can detect the Page ID and change the display logic appropriately. Seen here:
Get Facebook fan page ID
If you really want to create applications for your clients, take a look at this thread:
http://facebook.stackoverflow.com/questions/6264080/create-a-facebook-application-programmatically
EDIT (Not being able to comment is horrible) in response to J's post:
There is not a way to create applications entirely programmatically, but you can get really close creating a user-flow around:
https://www.facebook.com/connect/create_app.php?api_key=[key]&name=app_name
Where [key] is the api_key of the parent application. It isn't documented anywhere so you should have a manual fall back in place. The link above does work to create a new Facebook application tied to the currently logged in user (the parent api_key does not seem to have any effect but it is required).
To determine the api_key of the application created, ask the user for the appropriate permission and query /accounts to retrieve a list of Facebook applications the user owns. Do this before and after the user clicks the above link to determine which one was just created. From there, have the user get a new access_token and get the appropriate permissions to modify application settings. You should then customize the newly created application.
Mike
This has been mentioned several times in the old Facebook forum.
Wildfire, North Social et al, do not create applications dynamically. It's the same application being installed by many clients.
How is this possible? Well, when a Page loads a tab application, Facebook pass you a signed_request parameter. When you decode this signed request with your application's id and secret, you will find inside the page id from where the tab application is being called. You can then use this to work out which of your clients is making the call to your code and therefore what content to deliver to the browser.
There have been changes to the Graph API recently to allow you to manage applications once created but you cannot (and likely will never be able to) create applications programmatically through the Graph API.
The second thread mentioned by Mike mentions child applications but this was deprecated from the Facebook code base some time ago and would not actually allow the creation of applications in the way I assume you want.

Facebook External Widget development with a single app

We're trying to develop a widget that uses Facebook APIs and other websites (e.g different domains) could embed. We do not want every website to create it's on Facebook app but we'd like everyone using this widget to be connected to our Facebook app.
The problem is that Facebook seems to authenticate only a specific domain for an app (Canvas URL).
Ideas?
Guy
Update: I just realized that for Facebook server API as long as I set the redirect_uri to a valid URL (as defined by the site url) then everything is OK. So I can let my widget call the login and set the redirect_uri to some page we hold on our server that will communicate with the origin. So far so good. Now the problem that remains is whether there's a way to do it using the Facebook JS sdk rather then having to invent the wheel. From what I see there I could find a way to make the JS SDK not use the window.location.href. Ideas?
you just need to create the app, then from the profile site of your app there is an link to let users add the app to their page. (this is also possible via a special link (see the docs))
but be aware, one page can only include your app once. so if you like your "customers" to have your app multiple times on the same page you have to create multiple apps but point the canvas and tab url to the same script.
The other way would be to add child applications directly for the user, so you can let your customers even set a customized icon. This is hard to code couse you have to use old apis (newer one doesnt support the functions anymore) and there is none to null documentation for it. (I have such an app running, if you want to see some examples drop me a note)

.NET Web Forms multiple product subscriptions under one account?

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.
