How to link a social account in my application?

Hi everybody, I am Chaitanya, I am working on a web application where one of the requirement is to give an option to the user to link his social accounts such as Twitter, Facebook in the registration page. If the user clicks it the application should be able to access the profile information, public information and send emails.

I really don't know how to do this. Can anyone please help me in this regard?

Thank you all in advance. Have a good day.

What makes you think that your application is so special that users will entrust it with their account information? I'm aware that some people think nothing of handing their email account info to Facebook and other sites, but I think it's a terrible idea, both from a privacy and a security point of view.

Hi Mr. Lester, anyhow the site is implemented in SSL and moreover we are working on an application which is just like paypal.

Using SSL only marginally improves the security of the approach.

I don't know what to make of the Paypal comment - are you implying that your app is to be trusted at the same level Paypal is? If so, be aware that Paypal's record in this regard is nothing to be proud of.

I can't say that it is highly secure or not, but it is one of my requirement. Please can you tell me how to access information?

Thank you in advance.

I suggest you read this first and then edit the title of your post.

You need to look at the API for each of the sites you want to work with.

Thank you Mr. David. Where can I get it?

...

So you want to interact with various social websites. Where do *you* think you should start looking for information regarding *their* APIs?

I really don't know that, I already stated that I am new to such things.

Maybe start by seeing if you can find something on the websites of the sites you're trying to interact with?!

I found links to developer information on both Twitter and Facebook, on their home pages, in about 20 seconds each.

Being able to find information is a *critical* skill for a developer--this is basic problem solving ability. "Where should I start looking for information about developing for Site X?" How about... "Site X"???

For twitter I googled "twitter java api" and it takes me to http://dev.twitter.com/pages/libraries#java. You can also go to twitter website and look for developer or similar section.

Thank you Mr. David and Mr. Vikas. I'll check those out. Thanks a lot.
