Share Facebook profile after Login - user_link - facebook

We have a platform where users get logged in with Facebook. Now on customers demand, we want to provide a feature where we will request logged in users profile link at the time of login via user_link permission and user can share that link to anyone with just one tap. And on the other end, the other user who will receive this link will able to see (on facebook app or on Web) the sender's profile and if interested they can get connected.
But the issue is, I am not able to see user profile got as user_link. Its seems like I can only use this link if he or she is already my friend. If so then how can I implement this feature in my app? also if I am wrong at any point please correct me.

Its seems like I can only use this link if he or she is already my friend.
That’s exactly what the documentation says, https://developers.facebook.com/docs/graph-api/reference/user:
link: A link to the person's Timeline. The link will only resolve if the person clicking the link is logged into Facebook and is a friend of the person whose profile is being viewed.

If so then how can I implement this feature in my app?
You can’t; Facebook has deliberately designed this feature with this restriction, to better protect people’s privacy.

How to automatically post to Facebook

Please could you help. I have created a website that allows people to upload listings of items they are selling. I want to know how to add the feature where when someone creates a listing, it automatically posts on the user's FB page, with a link to the listing on our website. Is this possible? Would the user have to log into our website using their FB account for this to happen? Thanks everyone for your help.

You need to create a Facebook App and use Facebook Graph API with publish_actions permissions to do that. Note that the facebook rules prohibit sending fully automated messages that the user has no control, your user must have the ability to edit the message before sending

How to authorize Facebook App for basic permissions without showing Authorization Dialog

From the documentation it seems that the user should always authorize the Facebook application even to access basic permissions.
However, sites like Rotten Tomatoes and Clicker.com auto-authorize the logged facebook user without showing the authorization dialog. If you visit one of those sites for the first time they will be able to access your public data without you authorizing it. If I go to the Apps on my facebook settings, an entry will appear showing that I gave access to those applications (but I DID NOT).
How can this be possible? Is it related to the "Instant Personalization" feature for selected partners?
Thanks
Well, I was doing some research and yes, it's all about Instant Personalization.
From Facebook:
We've partnered with a few websites to provide you with great,
personalized experiences the moment you arrive, such as immediately
playing the music you like or displaying friends' reviews. To tailor
your experience, these partners only access public information (like
your name and profile picture) and other information you've made
public.
From one of its partners:
Clicker.com
So -at the time I'm writing this- unless you're a partner of Facebook, you'll have to show the old OAuth dialog.
Hope it helps!

Login with facebook and storing important user information

The facebook "wave" has finally hit me and I see that it's now time to integrate the wonders of the Facebook API into my site. I'm a little worried about implementing a "Login with Facebook" button because my site stores information about each user, and I'm not sure whether or not the facebook login system will also store said information. Any user who registers to my site has the ability to "like" certain pages that were found while browsing the site, and the categories of each page the user likes is stored and linked to his username.
If the user were to "login with facebook" however, and thus skip my registration page, would the information about categories still be saved?
Even looking at StackOverflow.com, I notice that all of my profile information etc. is being saved, but where? I used the login with facebook button so where exactly is my profile information being saved?
When you login with Facebook your site gets a Facebook ID and some other information (depending on what you ask for, but normally first name, last name, email address). You can then use the Facebook ID or email address to link it to an existing account in your system. If you can't find it, automatically create a new account with the details provided from Facebook.
You can use the Registration Social Plugin that facebook offer in order to get the data you need from the user while they register to your site using their facebook profile.
Also, as #JonGrant wrote, you can just use the api to get the needed information from facebook, just take into consideration that the more permissions you ask for, the less users will authorize your app.
Edit: Plugin now out of date, please refer to Facebook Login.
This was plugin removed as of API version 2.0. It will stop working
on July 30, 2015. Apps using this plugin should migrate to Facebook Login.

Anyone know of a good tutorial for Facebook authentication?

I'm linking my app to Facebook, and would like people to log in with their Facebook account, but I can't figure out how to do this. I had read up on Facebook Connect, but it seems that that's not used any more - but every tutorial I can find seems to refer to it. When I try to follow them, it doesn't work, because the interface has changed.
So, can anyone direct me to a tutorial or guide to doing this the new way?
Basically, what I want to do is this:
A user who is signed into Facebook and comes to my webpage is automatically logged in to my app (with the usual Facebook 'granting permission' windows etc), or can sign in with their Facebook account if they're not already logged in.
I then want to use Facebook to link users with their friends who are also registered on my site, so they can share things.
I would also like to have access to Facebook comments made on wall posts from my site - so the comment stream for a particular post can be seen on my site as well as on Facebook, and comments can be made on either.
If anyone can point me in the right direction (or even tell me what I should be typing in to Google!) I'd be very grateful.
Thanks.
Some sample apps that do many of the things you speak of are shown here. The Graph API is probably your best bet right now for delivering the content and access you need and there are numerous tutorials online for how to use it, including the Facebook Developers site itself.
You will find good Tuts on ThinkDiff, e.g.
http://thinkdiff.net/facebook/new-javascript-sdk-oauth-2-0-based-fbconnect-tutorial/
http://thinkdiff.net/facebook/php-sdk-3-0-graph-api-base-facebook-connect-tutorial/
http://thinkdiff.net/facebook/graph-api-iframe-base-facebook-application-development-php-sdk-3-0/
I know this is an older question, but the current method for authentication is OAuth 2.0.
Facebook provides a pretty good outline of what steps are necessary in this Reference:
https://developers.facebook.com/docs/authentication/client-side/
This example allows the authentication to occur entirely in Javascript on the client side so that you can request a potential user to authenticate via Facebook and then confirm access to your application.
If the user is already logged in, only the access confirmation for your application is performed.
If the user is already logged in and access has already been granted, the user is not required to login, or reconfirm access.

Social Media Linking

I've done a little searching and was wondering if there is a way to link a users account in our web app with their social media accounts they choose to link (facebook, twitter, etc). i.e. when they log into our web app they are auto logged into facebook, twitter, etc?
I see facebook has an api to login to our web app using their facebook book account but I want it to work the other way around, I want them logged into facebook when they log into their account via our web app.
Thanks,
Ryan
It is definitely possible-from your question I assume you would like to pull data and make actions on behalf of a user? If so, you will need the offline_access permission as well as all the other permissions you will need (check out the list here to see exactly which ones you require). Then, you can trigger a script on your server that tell facebook as soon as the user is logged in to your site, to log in your application as the user as well.
NOTE: You might be going about this in the wrong way. I would advise that you specify a bit more details on what exactly you need the user to be logged in for, and I can (probably) provide you with a decent answer.
EDIT: In response to your question in the comment, Ryan, here is my answer:
You need to divide this problem into 2 different situations-one: your company wants you to write all the code from scratch and don't use what facebook has to offer, in which case you should create a custom login script that enables your users to use their facebook account as the Actual user account in your web app. This is the best solution in my opinion, and is supported by the ever-so-awesome Jeff Atwood. Here's a link to how to do just this, and a tutorial about this also.
Or your company is comfortable with using Facebook's Social Plugins.
Then you should focus on Like Button & Comments : These social plugins are the best way to enable people to create social experiences if they're already logged in.
