Facebook - refer a friend - facebook

I'd like to enquire with the Facebook heads on here about how best to do the following:
I'd like to run a promotion from my Facebook business page that encourages users to recommend a friend in order to gain access to enter a competition. Obviously being in the Facebook environment it would be preferred to encourage Facebookers to refer friend's on their profile. Anybody know if there's an app out there (I've searched and not found) that does this? Does the Facebook API allow access to select specific friend(s) to notify on Facebook?
Thanks for your help & suggestions.

Yes, you need to have read_friendlists as an added permission to your facebook app.
From there I think you can do a FB.api() kind of call to get that information

I think the requests dialog does what you were looking for?

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

FB Graph API How can I get the list of all user ever logged in my app?

It's possible to access through Graph API (or any other way) the list of all users logged in the past to my FB app?
Thanks

There is no way to get that information, unless you store it in your own database.
You can see how many people using Facebook analytics. You cannot see their usernames, email, etc- you might be able to extend the analytics with some development to include those... but they dont come configured out of the box.
Here is a link to Facebook App Analytics:

Facebook Permission For Use of Content

I am hoping a Facebook developer will see this and get back to me. I am working on a science fair project and wondering if it would be ok to download some of my friends profile pictures so I can write a program that use it for facial recognition? I have realized that Facebook's API does not support this when I tried to use the Facebook Graph Explorer API, but I just wanted to know to make sure that I have Facebook's permission to do so.
Just ask your friends for their profile pictures, no need to ask Facebook for permission
It´s very simple: do not use ANY data/media from anyone without authorization. That means, you can create an App, let your friends authorize it and then get the profile pictures of your friends. And you need to make sure everyone knows what you are doing with their data/media.
It´s not even just about Facebook, it´s a general data usage rule not to use anything from anyone without authorization.

Is there a way for users to invite their friends via LinkedIn using iPhone sdk?

I am done with login using linkedIn but I did a lot of goggling and did not find a way to invite friends via LinkedIn. If Somebody have done this then please give me a guidance or tutorial to get rid of this.
Any help will be appreciated..
Thanks in advance
Once logged in, you should be able to invite people as friends using LinkedIn's own API. Check out the documentation here. This will involve POSTing XML to the API as described on that page.
Note that there are some "usage guidelines" you'll need to follow, too (The user must be given a choice about whether to send the invitation, etc...)

Get application liker via graph api

How can i get all the facebook user id whose like my application via a graph api.
Please give any suggestion.
Like facebook fan page showing application liker randomly. I also want to access my application liker list and want to save in database.
Please tell me if any possibility? Need your suggestion...
Thanks
Sorry, I don't think that's possible for privacy reasons Facebook doesn't allow it. You need to get people who like you application to install and authenticate it before you can find out more about them. However, I do remember someone managing to scrape the fans of a page before so maybe that's possible for applications as well...
