I'm trying to run the samples but having a couple of problems.
1. the CASPNETWebRegistrationForm - I get an error of "Invalid 'client_id'." when I run app. I've set the app id and key in web.config.
I just can't get the CASPNETWebsite to run - I always get a response from Facebook that says "An error occured - please try again later"
The URL returned from Facebook is https://www.facebook.com/dialog/permissions.request?api_key={185034998201688}&app_id={185034998201688}&display=popup&fbconnect=1&locale=en_US&method=permissions.request&next=http://static.ak.fbcdn.net/connect/xd_proxy.php%23cb%3Df9b7e2c4%26origin%3Dhttp%253A%252F%252Flocalhost%253A5000%252Ff7f1e1a04%26relation%3Dopener%26transport%3Dpostmessage%26frame%3Df36d8dadac%26result%3D%2522xxRESULTTOKENxx%2522&return_session=1&sdk=joey&session_version=3
I notice the api-key and the app-id are the same... but I have correctly setup web.config.
Any thoughts ?
I could be wrong, I'm not having much luck with the samples, though I believe you should leave out the curly braces in the config ie.
appId = "185034998201688"
appSecret = "185034998201688"
Have you filled out all the facebook application settings on the facebook webpage. I found i was missing the Canvas URL and a few other URLs, and filling this out made things work a little better.

I am currently developing an app with which visitors of an event can take pictures using a webcam and upload them to Facebook using an AS3-application. I know I can connect to Facebook, because I can log the user out using the API and I can get all the information. The problem is that I can't post to their wall for some reason. I keep getting the following error:
error #2032: stream error. url: https://graph.facebook.com/********/feed
I use the following code to post to Facebook:
private function postFB(e:Event=null):void {
var _params:Object = new Object();
_params.uid = Facebook.getAuthResponse().uid;
_params.access_token = Facebook.getAuthResponse().accessToken;
_params.message = "I was at the Thanksgiving Day Event.";
//_params.picture = _bitmap;
Facebook.api("/me/feed", postComplete, _params, "POST");
}
As I've said before, I know I am connected to facebook because if I change "POST" to "GET" in my api-call, I get all the information of my account. I have the correct permissions as far as I know (read_stream, publish_stream, user_photos). I use GraphAPI_Web_1_8_1.swc as an api.
The documentation on the entire api is very poor, so I am trying to figure out the problem. It's been a few years since I've tried any of this, so my code has probably aged too far by now. So, any ideas what I'm doing wrong?
publish_stream is deprecated (since years?), you need to use publish_actions.
If that does not work, make sure the Access Token includes all the permissions, you can test this in the Debugger: https://developers.facebook.com/tools/debug/
Side note: AS3 is not getting used very often anymore, the last version of the the AS3 SDK is from 2011. It may be a good idea to switch to the JavaScript SDK.
This question has been asked a few times on Stack, but there have been no real answers. Let me try to explain my situation anyways.
We use an application that uses Facebook OAuth2 login. This login used to work fine till last week, and all of a sudden it is troubling us now.
Application Flow:
Step 1: User presses login with Facebook button on our website
Step 2: Redirected to Facebook login/authorization page
Step 3: On authorizing the app, the callback comes to our application, with a short lived "code" param.
Step 4: This "code" param would be exchanged for a 60 day Access token using "https://graph.facebook.com/oauth/access_token" URL.
Error in Step 4:
When we try to exchange the short living "code" for the access token, we get this error from Facebook.
{"error":{"message":"This authorization code has been used.","type":"OAuthException","code":100}}
Observation:
For users who are newly coming to the application, the above-said error does not occur.
For a returning user this call fails with the above-said error.
Our application is live for more than 9 months now, and this error has come only in the past 7-10 days. We have had thousands of users using it successfully prior to that.
What I already got from Forums:
Here is my interpretation of what I read. May be inaccurate.
Facebook has some weird policy that necessitates the app developer to maintain the temporary 10 minute code until the 60 day code that was obtained during the first login expires. So we should create a cookie with the Access token on the user's browser. I was even able to see people modifying their code in order to create the cookies.
What's really bothering me?
The suggested solutions assumes that the cookie that they create would be present in the user's browser always. This is a bad assumption to make, as the cookie may be erased at any time.
I have another app Id/app secret that I use for my development (i.e localhost), and that works perfectly. The login happens fine out there, But its only the product machine that has the problem.
This problem didn't happen on the production machine for nearly 10 months since we launched the app, and it has come all of a sudden. Worst of all, I am unable to get any record of recent changes that breaks this flow.
Edit:
Platform: Python, Google Appengine. We do not use any Facebook SDKs, we make direct HTTP Calls to all the login URLs.
Call that fails : https://graph.facebook.com/oauth/access_token - we are passing the appId, secret and code (obtained from facebook) within 20 seconds of the first call happening.
Hope there is enough information here to show that our code is not totally incorrect. Any tips/pointers from people who have encountered and solved this problem is Welcome. If its a Facebook bug, and the Facebook dev comes to notice, I would be even happier.
I got round this issue by using a random GUID which is appended to each callback url i pass into facebook. It seems the code that facebook returns is made up of a few parts including the redirect_uri parameter you have to specify. By using this GUID trick, your app continues to work but facebook thinks it's a different URL hence generating a new code.
If you store that GUID in a temporary session, it's always the same. Here's a very cut down version of what I mean. I'm using C# but the solution will be the same:
Before i start the oauth process:
Session["facebook_buster"] = System.Guid.NewGuid().ToString();
Then to kick off the login:
var facebook = new FacebookClient();
var loginUrl = facebook.GetLoginUrl(new
{
client_id = ...,
redirect_uri = ..."/facebook/oauthcallback?buster=" + Session["facebook_buster"].ToString(),
display = "popup",
scope = "publish_stream,user_photos"
});
And then in my callback method, when I want to exchange that code for a new access_token:
var facebook = new FacebookClient();
dynamic result = facebook.Post("oauth/access_token", new
{
client_id = ...,
client_secret = ...,
redirect_uri = ..."/facebook/oauthcallback?buster=" + Session["facebook_buster"].ToString(),
code = Request["code"] // this is the returned code from the first method
});
Note in that second method i'm using the same session key so that the authorization code is successful.
Been testing this all morning by revoking permissions / manually changing my stored access_token (in my db) / removing my stored access_token completely and it works every time.
Hope this helps!
I struggled with this today for a while too. Not sure if you're using the Facebook PHP class (from what you wrote, it seems you don't), however, it could be a pointer anyways - the problem was that the Facebook PHP library seems to obtain the token from the code automatically and I was trying to do it again.
I new to IIS 7.5 and I need to integrate the Facebook SDK.
I not sure something to do with the php_curl or not but you can view the phpinfo http://goo.gl/ODQqR and I using the default example.php here http://goo.gl/STF7Z
This server is live so I can't risk to test and restart.
I have also enabled error_reporting(E_ALL); but it didn't display any useful message.
Please help me!

Update:
If I remove those $user_profile = $facebook->api('/me'); then it work.
Does this means I need to configure something from the facebook app setting?
The problem can't be identified, end up I written a ugly api instead of using official facebook API.
I'm using the following to get "manage_page" permission.
https://www.facebook.com/dialog/oauth?client_id=MY_APP_ID&redirect_uri=MY_SITE_URL&scope=manage_pages&response_type=token
But when I goto this link, it was successful and redirected to MY_SITE_LINK. But when tested on another FB user, it gives an error saying:
Sorry, something went wrong.
We're working on getting this fixed as soon as we can.
What happened ?
My_site_url is canvas URL? Like http://apps.facebook.com/…
Has anyone encountered the following error message when sending to Twitter?
"Error: Incorrect signature"
And on the debug console:
<0xf14cf80 SHKTwitter.m:(356)> Twitter Send Status Error: {"request":"\/1\/statuses\/update.json","error":"Incorrect signature"}
So far as I can tell I've followed the install instructions on http://www.getsharekit.com/install/#download and it is working with Facebook, e-mail etc. just not Twitter.
It would be great if someone has seen this error before and goes "aha!".
All I did to enable twitter Sharing is:
Regitered my App as a Twitter APP (Application Type: Browser)
#define SHKTwitterConsumerKey #"My..."
#define SHKTwitterSecret #"My..."
#define SHKTwitterCallbackUrl #"http://www.anything.com/callback" // You need to set this if using OAuth, see note above (xAuth users can skip it)
\#define SHKTwitterUseXAuth 0 // To use xAuth, set to 1
\#define SHKTwitterUsername #"" // Enter your app's twitter account if you'dlike to ask the user to follow it when logging in. (Only for xAuth)
Note that for the callback function you can enter any URL you want. even www.google.com. Just make sure it is the same URL in your code.
The issue is that you're signed into your twitter account, and allowed the app to connect to your profile.
However, days go by, the Key and Secret change, and now you're seeing this error. It's because you have to log out and re-log back into Twitter. I spent waaay too much time finding this out when I created a new Twitter App to hook into (and organize my apps) and found this error.
Basically, ShareKit is saving your login info, auto-logging you in, and getting the error when twitter says the app doesn't have permission to connect to your profile.
Follow these steps to log yourself out and test again :

Twitter API status update always returns "Incorrect signature"
