I'm trying to set up my app for the App Center and have come across an issue on the mobile site preview.
For the main Website preview Facebook is passing the code auth token parameter in the query string as expected. I am using this to login the user and display a personalized experience as they ask for in the guidelines.
However on the Mobile Web site Facebook is not passing this parameter after authentication. The only alternative seems to be to use the Javascript SDK to automatically login the user.
I've also noticed that on the preview page the Website version links directly to my website whereas the Mobile preview links to the m.facebook.com/apps URL, though they should be set up the same.
I also have this problem, but with the very Website option, as I don't use the mobile one. As a matter of fact, I have never seen the code in the query parameters coming directly from the app center, and I have been doing this for quite a while.

I have this desktop windows app written in C#
The user can post an image to his wall from the app. I have already created the Facebook app. In the previous version the win app would upload the image to my web site then the user was directed to https://www.facebook.com/dialog/oauth/ (via Process.Start(…) that would open the default browser) with my Facebook apppid and a redirect_uri and after authentication and obtaining an access_token the post image dialog would open. It all worked fine.
However, my question is if I could do these stages without a web site of my own, directly from c#.
I have seen plenty of examples but most of them refer to aspx, php and javascript but after all this is a few http request so I think it should be possible.
I think the main problem is how to get an access_token if there is no web page that the user is directed to after login.
I have seen an example using the webbrowser control but it wasn't very clear. And also, if possible I rather that the user would login using their default browser where they are most likely already logged in to Facebook and don't need to enter user and password just for this.
Also, is it possible to upload an image to facebook directly from my app without putting it on some public url first.
Any help would be appreciated. Thanks
I have an FB page tab store and currently we are trying to build a mobile optimized site using the same set of code.
m.siteurl is the mobile site URL (both web and mobile shares the same set of code). Everything works fine except Facebook and Pinterest share.
I was able to share in FB two to three time, but most of the time nothing happens. Pinterest didn't work for me in mobile.
As mentioned above m.siteurl is my mobile site URL and if I take the same in desktop every thing works fine, only with the mobile browser I have issue.
We are using FB.ui javascript method with parameters method,link,picture,name,description. Is there any additional parameters or method to take care this.
Please can anyone help.
Thanks in advance.
Even i am stuck with it. The fact Jscript-sdk uses popups for its actions. So share button Fb.Login() methods wont work in mobile. I myself had to change my website with a manual fb login instead of js-sdk.
I have a Facebook app the currently consists of 3 elements - an App on Facebook, Mobile Web, and a Page Tab.
Currently if I use the app URL it detects whether I am on a mobile or not and directs me to either the app on Facebook or the mobile web site.
What I'd like it to do is always show the app in the context of the page tab. Is there anyway to force this?
I tried looking at whether I could use the page tab URL directly and have that redirect to the mobile but depending on how I've linked it either returns a 404 or just takes you to the Facebook page. I appreciate I could do my own mobile detection but I thought I'd check if I'm missing something in Facebook first.
I wrote an explanation of how to do this here: https://stackoverflow.com/questions/14434072/create-facebook-page-tab-and-publish-template-on-it/14455665#14455665
Hope this is what you are after!
we have created a Facebook app, but when opening this on a mobile (via Web or iPhone) the page results in a 4oh4 error. I have setup a Mobile Web URL but still (after 1 hour wait) gives a 404.
Do I need to make specific changes on my app?
Please help.
This is expected as #Igy stated. You will need to have a handler to support redirecting mobile users to your apps.facebook.com/ or you can redirect them out of Facebook to your own URL if you are going to try and link to your page directly with an app embedded as a tab.
i.e. point link to http://yoursite.com/redirector
is mobile goes to http://yoursite.com/myapp or http://apps.facebook.com/
non mobile goes to http://facebook.com//app_
Some things to note:
You won't get any page specific data back from facebook on your page (i.e. Liked or Not Liked).
Based on #1 you won't be able to restrict the non-liking app users from a page.
After trying everything under the sun to get Facebook to redirect to a mobile web URL, here is what I needed to do in order to get the redirection working:
Make sure the Facebook application is a canvas application. This gives you the ability to give the application a namespace.
Give your application a namespace so that you can access it through https://apps.facebook.com/NAMESPACE. From here, Facebook will do the detection for you, and if needed, redirect your users to your specified mobile URL.
Make sure your app is NOT in sandbox mode.
If your app is in Sandbox Mode, Facebook won't redirect you to the mobile version you have specified in your app settings.
Facebook does the redirecting for you, you don't have to. Although their version of what "mobile" is and what you deem "mobile" might be different.
We have a post on a FB wall. It points to http://tinyurl.com/{something}.
When the link is clicked in a non-mobile web browser, it works fine: TinyURL redirects the user to our web site using the appropriate URI including a special querystring.
When the link is clicked in a mobile web browser on my Android, it fails with the error in the title of this question.
When the link is clicked in the FB native app for iPad and in Safari on the iPad, it works fine.
I have tried adding our URL to the Mobile Web setting in the Basic Settings tab of the FB App configuration. That results in all links pointing directly to the root of our web site with a funky set of parameters in a querystring -- in other words, it doesn't follow the TinyURL in that particular case. The funky parameters include "refid", "ref", and "ft".
So primarily my question is: Why, when I specify the URL in the Mobile Web setting as described in the previous paragraph, does it redirect to our main URL instead of the TinyURL link originally called for?
I think this is something Facebook broke very recently (perhaps even today?). When a user clicks on any links to our app from inside the Facebook native iOS app, they get this error "Either this application has not configured its Mobile Web URL or the URL could not be verified as owned by the application. Unable to redirect." We had never set a Mobile Web URL previously, and everything had been fine since we launched the app over a year ago. We sent all mobile clicks to the same URL's as desktop browsers and handled the mobile rendering server-side. We have not changed our application domain inside the App Settings or anything like that.
In the App Settings, can set a Mobile Web URL to our homepage and the link works (and the error message goes away) but that's not the desired behavior at all - it would mean that all links end up at the same Mobile Web URL regardless of what the link was!
Was this change made on purpose by Facebook and if so why? There's been no mention of this whatsoever on the Developer Blog.
Update 3/21 8:10am PST:
I've since found this to be a widespread problem, not just for a few apps. Just by clicking around I've seen this error on posts to weather.com, youtube, msn.com and a dozen others. It happens on both clicks from the Timeline as well as the News Feed (although strangely sometimes the same post works on one, but not the other!), and from the m.facebook.com mobile web app as well as the native iOS app.
I commented on http://developers.facebook.com/bugs/302635863137683 but no word from Facebook yet. I can't believe more people aren't talking about this right now, this is a major bug.
In your app, go to Settings -> Add platform -> Website
Add both, Website URL and Moblie Website (Yes, you need these both), then your app will be able to be opened from facebook native app.
You will also need the FB Canvas.
Same here, I recently noted that all links of items shared with our Adroid or iPhone app are broken. This only happens with the mobile version of Facebook the Desktop web version is still working. What is actually wrong on the mobile version is that the original shared url is replaced with a m.facebook url that ends with "?ref=unknown&refid=0&ft=fbid.332036910178718%3Ainterface.m_touch%3Ac.m" When user click on it Facebook is redirecting the user to the App's "Mobile Web URL" + "?ref=unknown&refid=0&ft=fbid.332036910178718%3Ainterface.m_touch%3Ac.m" instead of the original shared url.
My opinion is that this is an issue of Facebook that is redirecting the url to the wrong location, "Mobile Web URL" instead of the original post url.
Ok not working. What is going on, 1st directed to something about itunes url. I am on an Android not an Iphone. Sad state when an disabled person is unable to gain access the same as others. This is bad for all users.
