I will try to explain a bit the context for my problem.
Context:
A while ago I started working on Facebook application. One of the requirements is to be included in a Facebook page as a tab. This application will contain on a page a send button in order to be able to make it more engaging with specific people, users of the application would choose on their own. The reason behind this is because the Facebook page containing the application is related to alcohol, and "liking" the application will get more audition and potential children. Another reason for using send button rather then other similar options from Facebook (like send dialog etc.) is because in Facebook documentation was stated that send button works on mobile devices and other options don't.
Problem:
My problem is related to the send button. What I need is to be able to completely configure the send button: url, image, title, description. I have research the open graph tags in order to be able to do this. Everything works fine if the page I want to be sent with the message is a website OUTSIDE Facebook. Once I started to use the url of a Facebook page (let's call it www.facebook.com/mycustompage), then the crawler takes the images, title, description from facebook.com ignoring the actual page and the produced message is not what I want.
I have searched a lot to better understand this limitation and could not find anything relevant.
The only article I could find as a potential solution was (and even this I had trouble finding):
Send button returning error codes, like button works fine
The above discussion is a workaround which I have already put in place but is not 100% what I want. The described workaround is about putting in the send button:
<div class="fb-send" data-href="http://www.mycustomdomain.com/og"></div>
a page that sniffs the user agent. In case the user agent is Facebook crawler to serve an html empty page just with the open graph tags, otherwise redirect to the desired URL - which in our case is the facebook page www.facebook.com/mycustompage.
The message produced contains:
the title which is a link to www.mycustomdomain.com/og which when
clicked opens a page in a new tab with the address
www.facebook.com/mycustompage - this is relatively ok
under the title I have a "sub-title" readonly text containing the domain of the link: www.mycustomdomain.com - THIS IS NOT OK since I don't want to share where I have hosted the application.
the image and the desired description - this is ok.
Conclusion:
What I want to know if there is a better way to do this rather than this workaround.
If not I would like to know how I can hide for the produced message the "sub-title" so that the hosted domain is not visible.

I have a question about an app page function on Facebook.
https://www.facebook.com/InternationalDelight/app_481604621851046?ref=ts
in the link above there is the blue stick header, followed by a silver or white bar with four items.
An avitar/icon image
A button that allows a direct link to the owner's Facebook page attached to a another drop down button.
Now the last button is the one I am curious about. It allows the splash page (in the content area) to be liked then it redirects the person to the offer.
I have my app in sandbox mode, I am wondering:
Is this is an app that I can add
Is it a custom built function
A standard feature that I have not seen because my page is not live.,
How I can duplicate the functionality of the entire bar?
I have dived into Facebook the API and Facebook graph but I honestly don't know what to look for or what it is called.
On inspection the container div says...'stickeyheader' probably becasue it is sticking itself to the blue header...or timeline and 'timelineStickyHeader' and 'visible'... but how they got it to behave this way is beyond me.
Anyone familiar with this action/event? Let me know if I need to add more details.
Thanks!
Here is the answer (in case anyone bumps into this down the road). There are a few steps to putting your app on Facebook via and iFrame (basically a application that is hosted somewhere else but that requires some Facebook like button interception.
First you build your application. Creating a landing page (this will be tabbed later). In the header of that page look to intercept the user Facebook date to see if they currently like your page. If they don't then set up a function that stops them. If they like the post back/processing of the page on the like button click will set the conditions for the user to pass through to the app. This is like-gating.
Now, to develop the application you have to go to developer.facebook.com and create an account. There are two ways you can intercept the like/user date...
Here was my original code (it is in Coldfusion and Javascript):
<cfscript>
//Decode the signed request
fb_str = listToArray(FORM.signed_request, '.');
//Facebook use strtr
fb_str = replacelist(fb_str[2], "-,_", "+,/");
//For some reason their base64 needs padding out to match a base64 length
pad = repeatstring("=", 4-len(fb_str) mod 4);
//Decode it
result = ToString(BinaryDecode(fb_str & pad, 'base64'));
//JSON-ify it
liked = deserializeJSON(result);
//Clean up and release memory
fb_str = pad = result = '';
</cfscript>
<cfif liked.page.liked eq 'YES'>
<script type="text/javascript">
top.window.location = 'http://apps.facebook.com/parentsavvybook/';
</script>
</cfif>
That goes on your Coldfusion page (or other server-side scripting equivalent).
More can be found here: http://www.facebook.com/note.php?note_id=10150169691075844
Then in the developer tools you want to choose web app, then click the button that says create a new app. Fill in the application information, like what the domain is, and the name of the app.
The important stuff is the tab set up.
Add your app URL (where your web app is hosted to point to the page that has the FB script code/redirect stuff.
Once it is created you'll have an app ID and app URL.
The KEY
The key was this little stupid bit of code.
http://www.facebook.com/dialog/pagetab?app_id=YOUR_APP_ID&next=YOUR_URL
Why was this important. Well the Facebook page might be managed by you, but you will not be able to attach it to the page. You'll go crazy for days trying to get it linked up.
Fill in the missing parts above and go to the link.
You'll be prompted with a drop-down that will let you attach it to your page, or a page you manage.
Here is another post that hits the high points.
http://blog.hubspot.com/blog/tabid/6307/bid/26330/How-to-Create-Custom-Tabs-for-Facebook-Business-Pages.aspx
I hope this helps someone who struggled with FB apps and tabs to get the like button and how to interact with it and then finally attach it.
We are developing an app that makes posts on behalf of our users to Facebook. Within those posts, we want to put links to external (non-Facebook) websites.
Looking at the links in the status bar of the browser (usually Chrome), the correct URL is displayed. However, Facebook seems to wrap the actually-clicked link into some extra bells-and-whistles. Usually, this works correctly.
Sometimes, however, this URL wrapping ends up sending the click to a URL like:
http: //spywaresite.info/0/go.php?sid=2
(added space to make it non-browsable!) which generates Chromes severe warning message:
This happens very occasionally on Chrome, but very much more often in the iOS browser on the iPhone.
Does anyone have any pointers as to how to deal with this?
EDIT
For example, the URLs we put in the link is
http://www.example.com/some/full/path/somewhere
but the URL that actually gets clicked is:
http://platform.ak.fbcdn.net/www/app_full_proxy.php?app=374274329267054&v=1&size=z&cksum=fc1c17ed464a92bc53caae79e5413481&src=http%3A%2F%2Fwww.example.com%2Fsome%2Ffull%2Fpath%2Fsomewhere
There seems to be some JavaScript goodness in the page that unscrambles that and usually redirects correctly.
EDIT2
The links above are put on the image and the blue text to the right of the image in the screenshot below.
Mousing over the links (or the image) in the browser shows the correct link. Right-clicking on the link and selecting "Copy Link Address" gets the fbcdn.net link above (or one like it). Actually clicking on the link seems to set off some JavaScript processing of the fbcdn.net link into the right one... but sometimes that processing fails.
I'm not 100% sure what you're asking here, but i'll tell you what I know:- are you referring to this screen on Facebook?
(or rather, the variation of that screen which doesn't allow clickthrough?)
If you manually send a user to facebook.com/l.php?u=something they'll always see that message - it's a measure to prevent an open redirector
if your users are submitting such links, including the l.php link, you'll need to extract the destination URL (in the 'u' parameter)
If you're seeing the l.php URLs come back from the API this is probably a bug.
If links clicked on facebook.com end up on the screen it's because facebook have detected the link as suspicious (e.g. for URL redirector sites - the screen will allow clickthrough but warn the user first) or malicious/spammy (will not allow clickthrough)
In your app you won't be able to post links to the latter (an error will come back saying the URL is blocked), and the former may throw a captcha sometimes (if you're using the Feed dialog, this should be transparent to the app code, the user will enter the captcha and the dialog will return as normal)
If this isn't exactly what you were asking about please clarify and i'll update my answer
Rather than add to the question, I thought I'd put more details here.
It looks like the Facebook mention in the original title was mis-directed, so I've removed it.
We still haven't got to the bottom of the issue.
However, we used both Wireshark and Fiddler to look at the HTTP traffic between the Chrome browser (on the PC) and Facebook. Both showed that Facebook was returning the correct URL refresh.
Here's what Wireshark showed:
What we saw on Fiddler was that our server is issuing a redirect to the spywaresite.info site:
We are working with our ISP to figure out what is happening here.
I've been reading guides and examples for a long time (hours) but I can't manage. I tried to use all html meta tag like title, description, and og:property. Also tried to use the link sharer and also to create a new blank page with just the info I want to share to facebook in order to test. Also I tried to generate an random url in php so to have always a different url variable (the url to share and also the url of the main page containing the script). I also grabbed (url linter) a lot of time the url to clean the cache of facebook. It always give me the title of the site domain as title or the url itself as the shared title and description. I don't know what to do.
The main web site is from joomla. In the code of index of joomla I put a php include if the url has the variable "articolo" id. This incuded php page has regulat head body etc. So maybe I facebook check the main meta of joomla first? So now I tried to open a popup with just the page for sharing. Look here: link
It's possible that the title is locked in, meaning that after X number of likes Facebook doesn't allow you to change it anymore. Can you give us an example URL you're having issues with?
EDIT
Ok, now the link you provided shows some very interesting output. http://modernolatina.it/wjs/index.php?option=com_content&view=article&id=96&Itemid=258&autore=6&articolo=6
First, you webserver, instead of sending back a 200 code, is sending back a 500 code.
Secondly the HTML your webserver is sending back has two HTML tags (Do a view source on the content returned)
Fix up those two issues and I think the linter will be happier with your page.
Test your page here:
http://developers.facebook.com/tools/debug
I'm trying to use Facebook Send Dialog in a WinForms frame with a browser control and direct URI (you can repro just by clicking the links below). It works fine with link=http://www.foo.com, sending the message properly if you enter a message and click "Send":
http://www.facebook.com/dialog/send?app_id=179873125388138&link=http://www.foo.com&redirect_uri=http://jonnewman.com/&display=popup&to=100002395463043
However, this fails with link=http://www.facebook.com or any path under it. Clicking "Send" just gets you "Sorry, something went wrong. We're working on getting this fixed as soon as we can.":
http://www.facebook.com/dialog/send?app_id=179873125388138&link=http://www.facebook.com&redirect_uri=http://jonnewman.com/&display=popup&to=100002395463043
The aim is to write a script to make it easier to send messages asking all users in a particular group to a page (prepopulating the recipient list). Since Facebook has restricted groups larger than 500 members, our organization has to move to a Facebook Page, and I want the Send Dialog to link the new Facebook Page. Why won't this work? Is there a workaround? Are there other criteria for what links Send Dialog will and won't send?
Also, is there a way I can determine whether the send occurred or not, for example an event to catch? Whether you send or cancel, the Navigated event is still redirect_uri/#_=_.
Once I have Send Dialog working, I will add Show-FBSendDialog to Facebook PowerShell Module, which already has numerous capabilities to automate Facebook from PowerShell.
ran some tests and it seems it is blocking any fb domain http://on.fb.me/91S2P8, sometimes this is temporary otherwise need to rethink...
I see your second link isn't working... but if you add your company page id or name to link it should work. following link works for me:
https://www.facebook.com/dialog/send?app_id=179873125388138&link=http://www.facebook.com/Intel&redirect_uri=http%3A%2F%2Fjonnewman.com%2F&display=popup&to=100002395463043
hope this helps
I got solution. I also had same problem. No post helped me. Solving error for 2 days.
There were posibility of two mistakes(that was done by me).
Link Parameter given in url should be working. I have linked to api namespace but not given SSL url. So it was giving problem. You can given your web site address.
And redirect_uri parameter should be working. Try to give redirect_uri to same page most probably.
Maybe this is a stupid question and I did not understand exactly how Facebook applications work but here it goes
I want to implement a small e-shop as a Facebook application and for the products to have like button. The application will be instaled on a business page.
The problem is that the link for the like post on the wall will be to the actual eshop not to the facebook application on the business page.(or is it possible to make it to the application (eg. when you click the browser goes to the business page, selects the eshop tab, opens the product)?)
So actually I need to make a eshop site with 2 templates one for outside view and one for IFrame facebook view.
Is it possible to detect (from code-behind not in javascript) If the request is from the iframe or directly from outside?
Or the solution is more simple.. create a small version of the shop for browsing products only to be viewed in facebook and a full shop for outside view and the only relation between them is that when you click the like post from the first one you go to the second one?
I think I have found a solution...
I have created 2 domains that point to the eshop
shop.domainname & facebook.shop.domainname.
And in code behind I can check the Request.Url.Host if it starts with facebook.
For the facebook app the canvas url will be with facebook.shop.domainname and the links from the like button will be for the shop.domainname.
In this way I should be able to use 2 templates for the site and detect witch one I shoul use....
