I am able to access a user picture in a web browser without providing an access token, using the url:
http://graph.facebook.com/ID/picture
I know it performs a redirection, but it works.
However, when trying to access the same url in an iOS HttpRequest, I get an "invalid_token" response.
Is it possible to get a picture from an ID, in iOS without a token? If so, how do I achieve this? If not, how is it possible using the web browser?
Thanks!
In case anyone else is stuck with this, apparently under some conditions you get an "invalid token" response from the facebook (graph api) if you use a POST and not a GET http request method. Switching to GET solved the problem for me.

I am working on allowing users to log in to my website using Yahoo. I have intermittent problems with Yahoo Oauth2. I will generate the url to request the authorization code and it will get to the Yahoo login sometimes. Other times I will get the window with "Uh oh Looks like something went wrong. Please try again later. Developers: Please specify a valid request and submit again." and the url will have error=invalid_request&error_description=invalid+redirect+uri
My request url is configured on the yahoo console. Also I am using https on a server connected to the internet (not a local machine)
My request authorization was created using the one in https://developer.yahoo.com/sign-in-with-yahoo
I have
https://api.login.yahoo.com/oauth2/request_auth?
client_id={MY CLIENT D}
&scope=openid
&nonce=4c29ac770b9b1d795b
&prompt=consent
&response_type=code
&redirect_uri=https%3A%2F%2F{MY WEB SITE}%2Fcallback_yahoo.php
I am out of ideas at this point.
Thank you
Apparently (maybe) something was wrong on Yahoos side. I created another application with the SAME configuration and the problem seem to have gone away.
I am working on an Angular 7 application that uses GraphAPI. I am trying to create an online meeting from this application.
Each time I send a POST request I get 'Forbidden' as response. I have used apis's with Delegated permission before and it works.
Since online meeting requires 'Application Permission' I am not sure where to specify it. Could anyone help me with this?
You specify the permissions in App Registration > your app > settings.
You have a problem with the way you are trying to access the token. I used to get the same error however, got resolved by passing userName and Password as well in the auth request and using grant_type as password.
Hopefully someone here can help me fix this. I have been trying to make a web app for twitter, I have setup my application in the developer section of the twitter website.
I have set a callback url in both the developer section and in my code.
Where I get stuck is I get a 401 Unauthorized exception when requesting the Access Token. The app correctly sends the user to Twitter to ask for authorization, and then twitter send back to my callback URL successfully. My webapp then tries to request the access token and thats when the exceptions happens.
Below is an example of the API I call:
https://api.twitter.com/oauth/access_token?oauth_callback=http://www.example.com&oauth_consumer_key=6Rfhub7fDgCIazdg4dMECT6fJ&oauth_nonce=1721260&oauth_signature_method=HMAC-SHA1&oauth_timestamp=1403965501&oauth_token=RCbfmuvzqFjJWHwCtWfNqEQ22uXFvv422AtHfBBYE&oauth_verifier=0QuTFy5SBmAl29VIWkBjfogJQ7GiSAoR2qIjokoii0&oauth_version=1.0&oauth_signature=JRzlH5Fiv5Ani3P+oXj5dxV58cA=
Any ideas where I might be going wrong?
Thanks
EDIT: Im using code from here http://www.aspdotnet-suresh.com/2012/05/add-twitter-login-authentication-to.html
and I changed it to use https:// not http://
Couldn't fix this issue. Using TweetSharp instead.
I'm trying to get a iOS client to make use of Yammer's Oauth2 to validate a user. I first tried the GTM-OAuth2 code, but I cannot get it to understand the response from Yammer. It appears that the GTM code is expecting the access_code as a query parameter, where as Yammer is returning it as a uri fragment. I hack he GTM code to see the fragment, but now it appears to be thinking that there is an error because the code and message fields are not in the response from Yammer.
I've also tried to use OAuth2Client api but the problem there is that Yammer does not seem to want to use the redirect_uri I pass to it, so Safari never gets the custom url and therefore never calls back to the app.
Does anyone have a working example of using Yammer's OAuth2?
I would also be interested if anyone has got GTM-OAuth2 to work with Facebook?
Yeah Yammer has a shitty implementation of oAuth. Looks like each service has taken its own implementation of oauth. anyway yammer requires the user to copy a 4-digit code from its website, go back to your service paste that code in your website. Only then you can request for access code.
check this - http://www.tutorialjinni.com/2011/04/yammer-api-example.html (its in php but hope you can get the gist).
Nothing you can do about it but a fun read - Yammer API sucks
The scenario is I want to post some details on a facebook page created by me from my other app. So want to know how can we give access to app through access token means how can we get the access token for this?
Thank You

Yes, take a look at the following URL and the "Page Access Tokens" section for information on how to do obtain a token.
API - Obtain Page Token
Note, however, that there is a known issue when trying to use the links api point, if you intend to define your own link in the post.
Bug report
You'll probably want to use the feed API point instead. I've not actually managed to get this working yet though, and I'm awaiting feedback from FB themselves. I'll update you if/when I hear something useful back.
Good luck.
You can get the access_token for you page by enabling the manage_pages permission, and then calling the API endpoint: /me/accounts to get the access_token for all the pages you manage.
You can then use this access token to post to your page using the Graph API call: /{page_id}/feed
