I need verification on an error to see if it is just me or a FB bug.
The preview image link of posted links doesnot seems to be working, either by Graph or FQL.
Try this one :
https://www.facebook.com/coca-cola/posts/168694756574160
With the graph explorer, go to
https://graph.facebook.com/168694756574160
and click on the "picture" link. Does the preview image appears ? I have a blank screen.
I see this behaviour on every posted links I could try.
Thanks for trying this on your side. If it is a FB bug, I will create a bug report!
The /picture connection of most objects returns a HTTP 301 redirect to the image's URL on the CDN. This will not work with the Graph API Explorer as it hasn't been coded to respond to the redirect.
The redirect allows you to put (for example) https://graph.facebook.com/USER_ID/picture into an <img> tag directly
If you want to retrieve the picture as a string, access /OBJECT_ID?fields=picture instead

My goal is to post to my FB page (/{page-id}/feed) a link to a website, choosing the image to show instead of the picture scraped automatically from the web page. The image I'd like to show is not in the web page, so I cannot use the og:image tag.
I'm using the current API (v2.9) and this is what I've tried so far in the Graph API Explorer:
the picture parameter, that does not work as expected (it doesn't replace the automatic image)
picture and link parameters both pointing to the image url, with an action button, but it must have the same url used for the link parameter
the child_attachments parameter, but I need at least 2 images and the final result is quite different, too
additional fields of the link parameter, but thy were removed in the 2.9 API
a lot of combinations between these parameters, with no luck
What am I missing?
For information regarding why it isn't working. I assume they removed it to force users to add it to their website like Twitter did with their Twitter cards and maybe to stop impersonating pages.

When adding a share button to my site as follows:
https://www.facebook.com/sharer/sharer.php?u=http://www.domain.de/christmas-gewinnspiel
When I click the button, it takes me to facebook and the the post to wall page, but the link text says "www.domain.de" although the URL of that link is correct ie. (http://www.domain.de/christmas-gewinnspiel), how can I change the the link text?
The page url is giving a 404 response. I think showing the basic domain is the standard behaviour for sharing, the link itself (if you'd click on it) is the correct one, but giving a 404 as described.
Also, think about adding the OpenGraph meta tags to make the shared info look nicer:

I'm creating a web app which uses Facebook feed dialog plugin in some pages. When I try to share these pages, the URLs posted to the news feed get truncated.
I'm using the direct URL approach. When the user wanna share something, she clicks in a link that is going to redirect her to the feed dialog. The link is composed as shown below:
https://www.facebook.com/dialog/feed?app_id=MY_APP_ID&link=SHARED_URL&redirect_uri=REDIRECT_URL
For example:
the URL I have in the "link":http://www.simplecity.com.br/DP/Index/?CID=0&UID=1
the URL I get in the news feed:http://www.simplecity.com.br/DP/Index/?CID=0
Has anyone already experienced this issue? Any suggestion?
The usual cause of this is forgetting to encode the link when you pass it into the Direct FB URL.
Are you forgetting to urlencode the link parameter (i'm especially thinking of the &) when creating the URL you're passing the user to?
I recently encountered the same problem with a straightforward link - I inserted:
https://example.com/page.html
into a page post. However, on the page it was rendered as:
https://example.com/page.ht...
as if the last two characters of the html extension were merely not displayed, as indicated by the elipsis. However, if you copy the link from the post you find that those chars are actually missing and the link resolves as 404. If you edit the post and reinsert the link, it is saved correctly, although the 'overflow' characters are still hidden by the elipsis. Very misleading.
What seems to work best is if you use the Facebook Developer OG tags in the page and then use Open Graph Debugger to scrape the link. This puts the URL in the FB realm and it picks up the correct link just fine. As you are doing this, the debugger tool gives you feedback to the effect: "This is the first time we have seen this URL"; which is baloney if you have put the URL on a FB page beforehand.
I have filed a bug report with Facebook; but I am not expecting them to own up to this bug.
I need some information, why like box frame not working: 'Could not retrieve the specified page. Please verify correct href was passed in.'. I`m testing this href in http://developers.facebook.com/tools/debug - it says correct answer, but frame not working.
In access logs for UA facebookexternalhit/1.1 always answer status 200 (and 301/302 for specific page).
example page: http://www.now.ru/item/series/comedy/Univer_222394
additional information: on some pages frame works, and some does not work
thanks.
The Facebook Like Box is really designed to use the URL for a Facebook page, not for a general Web Page. It pulls Timeline content from a fan page within Facebook.
It can be used for a Web Page if the page has defined Open Graph Meta Tags and has been Liked at least once. However, there will be no "stream" functionality. The Like-Box for a Web Page would just have functionality similar to the Facepile plugin (except that Facepile just shows you friends, and a Like-Box also shows non-friends.)
Typically, though, you would want to supply the Like-Box with a Facebook Page URL in the following format:
http://www.facebook.com/pages/Facebook-Page-Name/Facebook-Page-ID
Perhaps you are intending to use a Like Button or Facepile Social Plugin instead? Either of those can accept any URL as input.
I'm using the Graph API to post to a user's wall via a 3rd party website. The update contains a link to said 3rd party website. (In functionality, it's kind of like just putting a Facebook "Like" button on the 3rd party page, except I want some more finely-tuned control over how the caption looks on Facebook.)
I am not specifying a picture for the post. When the post is created, Facebook's bot automatically connects to the 3rd party page specified in the link and selects an image to use as a thumbnail. Sadly, the image is almost never relavant, and I would just rather Facebook not look for a thumbnail at all.
I can probably put some Open Graph tags on the page to help out Facebook's bot, but I don't see a way to use Open Graph to specify that you'd like to have no image, and that Facebook shouldn't choose one automatically.
Any way to do this?
Although Facebook seems to ignore the picture set to an empty string in the Graph API call, setting an Open Graph tag for the picture which is an empty string seems to have done the trick.
When you publishing the the stream, include the "picture" property in the request and just set it to an empty string. This will ensure you dont have a url on the post. My other suggestion would be to put the Open Graph tags on the pages you are sharing. This will ensure that both you and others who share the url will have the correct data and images show on Facebook. http://developers.facebook.com/docs/opengraph
