This url is giving me a internal server error (http://videos.sapo.pt/fiLm1Zo3kiTzFUIoWYtU).

The sample link provided at
https://developers.facebook.com/docs/sharing/reference/feed-dialog/v2.2#redirect
works for me:
https://www.facebook.com/dialog/feed?app_id=145634995501895&display=popup&caption=An%20example%20caption&link=https%3A%2F%2Fdevelopers.facebook.com%2Fdocs%2F%20&redirect_uri=https://developers.facebook.com/tools/explorer
but
https://www.facebook.com/dialog/feed?app_id=128738460473752&display=popup&caption=An%20example%20caption&link=http%3A%2F%2Fvideos.sapo.pt%2FfiLm1Zo3kiTzFUIoWYtU&redirect_uri=http://videos.sapo.pt/fiLm1Zo3kiTzFUIoWYtU
doesn't. Please check that
You app with the id 128738460473752 has configured http://videos.sapo.pt as a valid URL
URL Encode the link parameter

URL encoding the link parameter doesn't work anymore.
Facebook is now returning an error inside the popup if you do it.
You don't have to URL encode your link parameter, but you can just leave it as text.

Facebook callback url not valid laravel

I'm using Socialite plugin for login with facebook.
When I create application on facebook and when I put this callback url http://localhost:8080/code/example/public/facebook-login-callback
error
If you wish to change your callback URL your new URL must use SSL and start with https.
Any ideas?
Check App Domain and Site URL value in your facebook app. May be this is your solution.
The error message is quite straight forward there: Your callback URL needs to use SSL (means (amongst other things): it must start with "https").

Facebook privacy policy URL: Bad Response Code: URL returned a bad HTTP response code

I want to publish my first Facebook application and a Privacy Policy URL is required.
I have the page privacypolicy.html published in my website but I get the next message when I configure it in "App Details":
You must submit a valid Privacy Policy URL in order to be compliant with Facebook Platform. Request failed with error:
Bad Response Code: URL returned a bad HTTP response code.
The http code returned when I request the page is 200
Any ideas?
The URL is cached by facebook.
Adding # at the end of my Url did the job ..
This is an old question I know, but I figured I'd post my solution and hope it helps anyone. For me I got this error because I had rewrite rules that didn't catch the URL that Facebook actually goes to in order to get the privacy policy. Facebook adds a query string to the URL that you give it for the privacy policy and since my privacy policy page doesn't do anything with the query string, I didn't check for it in my rewrite rule.
You can check out how Facebook scrapes the page you give it by going to Facebook's Sharing Debugger and putting your URL in the input bar. You can also see the last time that Facebook tried to scrape that URL and tell Facebook to try again once you've fixed any issues. This will get around the caching that was mentioned in user2390340's post.
Facebook externalhit appears to request via the ipv6 address published in DNS if there is one available and won't check on the ipv4 published in DNS.
If your website doesn't have ipv6 enabled it'll return a 404 or 500 and you'll get that error "Bad Response Code: URL returned a bad HTTP response code" for your Privacy Policy URL.
Edit:
Also noted that Facebook caches the URL, I was checking it and getting a "bad response code" error even though there was no hit from their UA in the access logs.
Adding ?stuff onto the end of the URL in the Privacy Policy field bypassed a cache and the access log hits showed up with 200 OK, allowing the URL to be saved.
Not sure if this is related to user2259887's comment about Facebook using IPV6 DNS. But after reading his comment, I was able to work around the validation issue by specifying an IP Address URL instead of using the host domain name URL.
This workaround will not work well if the site IP address is dynamic or change often.

Facebook - OAuth Token - redirect_uri isn't an absolute URL

... but it is!
I am calling the facebook API with the following link in order to receive my access token:
https://www.facebook.com/dialog/oauth?client_id=myclientid&redirect_uri=http%3A%2F%2Fmydomain.org%3A8080%2FServer%2FFacebookAuthenticationVerificationServlet&scope=manage_notifications,offline_access,read_mailbox,read_stream,publish_stream
What am I doing wrong?
Facebook answers with the following error:
message: redirect_uri isn't an absolute URI. Check RFC 3986.
type: OAuthException
code: 191
It shouldn't have anything to do with it, but I am using java's URLEncode.encode() to encode the URL into UTF-8. I compared the result with that one from JavaScript's encodeURIComponent() and didn't find any difference.
EDIT: Do I have to set the domain into my configuration? I can't locate it on "App Domains" (because facebook doesn't allow me to add domains there with port configuration) but I set the domain as "URL of my website".
EDIT2: The unencoded redirect uri: http://mydomain.org:8080/Server/FacebookAuthenticationVerificationServlet
EDIT3: This has nothing to do with the :8080. I tested it with a php-script (URL was like bla.domain.org/myphp.php) and sent the code by the php script to the tomcat server, but the error persisted.
Okay, it turned out I misunderstood the OAuth protocol. I was fetching the authorizationCode that THEN leeds me to the accessToken.
But I wasn't able to fix that error in specific. I just redeveloped the procedure and implemented auth-code and access-token separation and it works fine now.
Maybe unauthorizating the app and reauthorizating it # facebook did fix it?
Error code 191 for Facebook is
API Error Code: 191
API Error Description: The specified URL is not owned by the application
Error Message: redirect_uri is not owned by the application.
Make sure mydomain.org is in the App Domains field, and that the Website with Facebook login field is correct.
You shouldn't encode redirect_uri. http%3A%2F%2Fmydomain.org is not understood as http://mydomain.org

The url supplied is invalid Facebook RestFB

I am using Facebook Graph using RestFB. When I am trying to post a URL to Facebook -
http://localhost:8080/demo
I even tried
http://www.wannaget.com/home
This is also not working. Issue was not local or live url. Because this was working previously But now it gives me invalid URL error.
It gives Following response
INFO: Facebook responded with HTTP status code 400 and response body: {"error":{"message":"(#1500) The url you supplied is invalid","type":"OAuthException","code":1500}}
I don't understand the reason why this is happening. Everything is working fine but now I am facing this issue.
The url is not in a valid format. I guess it has to end with an extension, like "http://localhost:8080/demo.html"
A workaround that worked for me (on rails):
I was trying to post on fb the link "localhost:3000/articles/53" with that same error.
To fix it I had the route:
match 'news/article/:id/x.x' => 'articles#show'
and post successfully on fb the resultant link "localhost:3000/articles/53/x.x"
Any real solution is welcome!
The URL you provided is a for a local server running on your machine. Facebook has to be able to access that URL but it can't because it is not on the Internet - it is only accessible from your local computer.
You'll have to give Facebook a real URL that is accessible by their servers...

Facebook API error 191
I'm developing a Facebook app. When I attempt to get an access token, I get the following message:
An error occurred with test. Please try again later.
API Error Code: 191
API Error Description: The specified URL is not owned by the application
Error Message: Invalid redirect_uri: Given URL is not allowed by the Application configuration.
https://developers.facebook.com/apps/.../summary
I've configured the app's domain (appsdot.xxx.com), name and other attributes.
What is causing this error, and how do I fix it?
The redirect_uri must contain the Site URL or Canvas URL as defined in your App Settings. I always get this error when I set a redirect_uri that doesn't contain the URLs in App Settings.
I got this error because I had a trailing slash on my Canvas URL and neglected to include the trailing slash in the redirect_uri.
be carefull error is about uri (i spell: Uniform Romeo India) and the most probably you are using word url (i spell: Uniform Romeo Lima) ... do you see the difference???
just add st like this:
redirect_uri: 'YOUR_PAGE_TAB_URL OR CANVAS_URL'
how simple,isnt it?
this just because of URL mistake
whatever website url is specified should be correct.
i mentioned website url as http://localhost:3000/ and domain as localhost
but in my browser i was running http://0.0.0.0:3000/ that was the actual problem so i ran server as localhost:3000 now its working fine. Because we mentioned site url as localhost fb will redirect to same, if we r running 0.0.0.0:3000 it will rise error that Given URL is not allowed by the Application configuration.
so becarefull with your website url you have specified in facebook app.
and the url you are running locally both should match
thank you
In my case, the problem was happening because I didn't configure the site domain in the right way.
You can access your site model by the admin and change the domain name from example.com to the real domain that you are using.
The best way to fix this is create a fixture; something like:
YOUR_APP/initial_data.json:
[{"pk": 1, "model": "sites.site", "fields":
{"domain": "127.0.0.1:8000", "name": "127.0.0.1:8000"}
}]
Make sure your domain is not being masked.
The base_url must contain the Site URL or Canvas URL as defined in your App Settings. I always get this error when I set a redirect_url that doesn't contain the URLs in App Settings.
You do have to register/create the url with facebook, by creating a facebook app. You might have to give the mobile phone number to them. The Site url you put in there needs to passed as the redirect url.
rails#{This error is related to URL}
-I just put the ip address in all the URL instead of localhost..now it's working file before doing that I tried so many things but didn't work..I am sure this one will work..
