I try to get the signed request to login the user via a webservice but I only have access to the accessToken on FBSession.
I saw this link
Facebook Signed Request for iOS (HMAC SHA256)
who shows how to convert the signed_request but doesn't show how to get it.
Need help :)
If I undersand you right you want your app to login and then make a call to a server where you need to check the users credential again.
I used this tutorial for the authentication.
Then when I call the server I send the accessToken property as a parameter to check the users credentials on the server. You can get the token value like this:
FBSession.activeSession.accessToken
On the server side you can then set the access token to the value you got from the app.
I compiled a gist that generates a signed request which you can then use to authenticate a user on your server without having to query the graph API.
You can find it here: https://gist.github.com/3962188
You can find the original question I compiled it for here: Facebook iOS SDK to return a signed request object upon login
Please note that most of the code is simply a compilation of existing open source code, but I haven't seen any fully working implementation like this anywhere.

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.
I am facing an issue regarding account linking in Actions on Google:
I am able to authenticate the user and access his email address and username however after this how can I redirect the user back to the google assistant and close the browser where he was authenticated?
Any help will be appreciated!
Update: Hey Prisoner thanks a lot for that.
I did what you said and yeah now it does redirect to google.com but without result_code=SUCCESS when I test it in the simulator.
The link is:
https://www.google.co.in/?gws_rd=cr&dcr=0&ei=z77fWbjQGIXxvATs_oqwBA
Now if I type talk to... again it shows me the message you need to link your account!
In the device the browser automatically closes and it shows SIGNING_IN however when I type an intent it is not recognized.
It would be great if you could point me in the right direction! (I am not sure but I might be at the token exchange stage that you mentioned, but I don't have a clue how to proceed!)
Update 2: As requested the entire flow that I am following:
This is the URL that I receive from debugInfo:
https://assistant.google.com/services/auth/handoffs/auth/start?account_name=cha***#gmail.com&provider=***_dev&scopes=email&return_url=https://www.google.com/
When I paste this in the browser the request that I receive at the authorization endpoint is:
ImmutableMultiDict([
('response_type', 'code'),
('client_id', ****.apps.googleusercontent.com'),
('redirect_uri', 'https://oauth-redirect.googleusercontent.com/r/****'),
('scope', 'email'),
('state', ' CtcCQUxWM2ROU3hNMjl4LUItVXhQSGd4THRMLU4yNExnb3lYbGRKQnQwa3NwTVFva19NUWpYNE5jNGJURzIyZFN3RDBXd2d4enFGVWJGb0Q0ZW1vaS1OaFdkaHdhb05HZ2xlWTR6SllKVlRWYktwd09faklyUTVheFhQbGw2dmVKYzVFTk05N3B1QkxaZG41RVdHN0wyTktvRFdCYzFPVFBzM1dQUlFtN2RmM1VtRU4****(state)')
])
The response (redirect_url) that I send back:
https://accounts.google.com/o/oauth2/v2/auth?scope=email&response_type=code&redirect_uri=https%3A%2F%2F******.herokuapp.com%2Fcallback%2Fgoogle&client_id=****.apps.googleusercontent.com
When it reaches my endpoint again the request arguments are:
ImmutableMultiDict([
('code', '4/***********')
])
Now I am able to access the email address and other details
The url that I redirect to from here:
https://oauth-redirect.googleusercontent.com/r/****?code=abcdefgh&state=CtcCQUxWM2ROU3hNMjl4LUItVXhQSGd4THRMLU4yNExnb3lYbGRKQnQwa3NwTVFva19NUWpYNE5jNGJURzIyZFN3RDBXd2d4enFGVWJGb0Q0ZW1vaS1OaFdkaHdhb05HZ2xlWTR6SllKVlRWYktwd09faklyUTVheFhQbGw2dmVKYzVFTk05N3B1QkxaZG41RVdHN0wyTktvRFdCYzFPVFBzM1dQUlFtN2RmM1VtRU4****(state)
This redirects me to :
https://www.google.co.in/?gws_rd=cr&dcr=0&ei=5c_fWdfKNYndvASO7o6ACA
Edit 3: I checked the network logs:
result_code=FAILURE&result_message=Account+linking+failed
I also added /token/google as the token URL in AoG. It is detected in heroku however I never receive this request in my code.
Note: I am using python flask and hosting my app on heroku
Once you have authenticated the user, you'll need to return a temporary auth code back to Google. Later, Google will exchange this auth code for an access token and a refresh token, but you're not there yet. The important part is that this code needs to be unique and that, later, you'll be able to recognize what user it is for. The code should be valid for a limited time - 10 minutes is a generally accepted time frame.
In the request Google sent to you as part of the login, they've provided a redirect_uri and a state as parameters. You'll need to use these in your reply. (state can be anything - you shouldn't care what it is, you're just going to send it back with your redirect. Its purpose is to improve security by preventing replay attacks.)
Verify that the redirect_uri has the form
https://oauth-redirect.googleusercontent.com/r/YOUR_PROJECT_ID
Where YOUR_PROJECT_ID is... you guessed it, the ID of your project. You can find this in the cloud console.
You'll then redirect the user to this URL with a few additional parameters:
https://oauth-redirect.googleusercontent.com/r/YOUR_PROJECT_ID?code=AUTHORIZATION_CODE&state=STATE_STRING
Where YOUR_PROJECT_ID is as noted above, AUTHORIZATION_CODE is the code you've generated, and STATE_STRING is the value of the state parameter that you were sent in the request.

Ive previously requested public_profile, user_friends, and email which Facebook will let you use pretty freely in my Swift iOS app but now I'm trying to update the app to request new permissions with loginWithReadPermissions but when it transfers to the login page it just says that I've already granted my app permission and doesn't request the new permissions. Querying the results shows no granted or denied permissions and looking at the Graph Explorer API on the Facebook Developer site shows the same. So I'm looking for suggestions on why my app might not be sending the updated request to the server.
I should note that I'm utilizing the AWS iOS Mobile SDK. I found another answer that overwrites the default Facebook sign in provider to add new permissions to the request but this has the same result.
Also in my output Im seeing the following string which contains all the permissions Im trying to request which makes me think that the request is going out but something else is happening
scope=email%2Cuser_birthday%2Cuser_hometown%2Cuser_friends%2Cpublic_profile%2Cuser_about_me
I am developing an iOS app and want to implement native sign in via Twitter. I am using an example I found here that includes 2 steps, request token and access token. For the second step I use my twitter ACAccount (account.framework) and my app consumer_key and consumer_secret, and finally obtain an oath_token and oath_token_secret.
The problem is that when I try to fetch data with that token in my app API I get invalid token.
I think a step might be missing here or something. I look at every post related to sign in via Twitter and couldn't solve this...
Thanks everyone
This is the example I based my code
https://github.com/seancook/TWReverseAuthExample
I did almost everything the same, I am using ARC
I am new to developing a Salesforce app and I am using OAuth 1 for authentication.
I am able to generate the Request Token, and I re-direct the user to the salesforce site.
Once I enter my credentials, I get a
Remote Access Authorization Error
There was a problem in setting up your remote access
with
oauth_error_code=1800
In my Login History page, it shows Status as Success for Application type OAuth.
I don't get any entry in my Debug Logs page.
I have enabled Development Mode.
Any ideas whats wrong?
So https://login.salesforce.com/services/oauth2/success is a stub URL for callbacks - and that is the screen you are seeing there, and the access_token variable is your session ID for the user. So the OAuth flow is working correctly.
In the code, you might check to see if oauthResponse.access_token is getting set correctly. If so, it looks like:
sfw.login( setupHomeView );
That is what should tell it to move from that page to the next UI page.
You might also check out the Force.com Mobile SDK (link). It also includes PhoneGap and has a great OAuth wrapper built in.
