LinkedIn API

LinkedIn is the worlds largest business social networking hub. Launched in 2003, LinkedIn has millions of users and is implemented in over 200 countries. One purpose of the site is to allow registered users to maintain a list of contact details of people with whom they have some level of relationship, called Connections. Users can invite anyone (whether a site user or not) to become a connection. LinkedIn actually provides 2 APIs: -The JavaScript API is a rich client library enabling you to build dynamic applications in the web browser. Use OAuth 2 to easily authorize users via the "Sign In with LinkedIn" button, access LinkedIn data with native objects, and interact with Plugins. -The REST API provides a simple, consistent representation of people, companies, jobs, and the interactions and relationships between them. Our query language lets you read data in XML and JSON at the granularity and aggregation that you choose. Use OAuth 1.0a to authorize users and begin making REST API calls using any programming language.

HI friends, how can i devloped my application on linkedIn site.


The LinkedIn guys are control freaks and they are doing all this just for the money. I'd never waste my time doing something with their crappy apis, sorry.

uff, why the hell they dont make the API more available/flexible!!! im sure it can involve a lot of users and developers like Facebook!

I retract my previous statement. THEY aren't really doing ANYTHING. It's NOT open. You CANT develop anything for them unless they let you. Even with YOUR OWN DATA! LAME!


Hi guys,

Wanted to integrated Linkedin API in one of my applications. I want to fetch user’s public profile details using his linkedIn username. But I am not able to find any documentation or sample to get this thing done. Can you please help me with this.

Any help will be very much appreciated.


Ajay Matharu


Hi Ajay, the LinkedIn API is available to developers by approval only and you will need to request access from their team.

Hope this helps.



Hi all,

Please let me know how I contact with their team to get the permission?



hi, can anyone help me here. this is where i am at...

i was trying to develop a business networking site which allowed content submission like news & articles which sites like linkedin currently dont offer.

i then came against the thought... what if i used linkedins already popular social base rather than create my own one and maybe create an app / widget or some kind of mashup instead.

can anyone share any ideas or help in creating this. how could this work, what methods could i use, is this a good idea?

email me to discuss or leave a post here.

thanks all!
