Over fifty million users entrust their professional identities and relationships with LinkedIn, helping build LinkedIn into the largest global professional network today. However, professionals around the world use a wide variety of applications and Web sites to get their work done, and they have spoken loud and clear that they want the ability to leverage their professional networks wherever they work.

Starting today, developers worldwide can integrate LinkedIn into their business applications and Web sites. Developer.linkedin.com is now live and open for business.

The evolution of the LinkedIn Platform

Over the past months, LinkedIn has supported integrations with some of the most prominent and critical software applications in the enterprise. Partnerships with companies like IBM, Blackberry (Research in Motion), and most recently Microsoft, have given us time to invest in both functionality and scalability of the platform.

Software is moving to the cloud, and business applications need context for who people are and how they are related. LinkedIn now is the obvious choice as a provider for those services. It is hard to imagine a business application that would not benefit from LinkedIn integration.

Roger Neal, SVP/GM at BusinessWeek Digital, McGraw-Hill

At LinkedIn, we have always believed that business applications are better when they are built over a platform of professional reputation and relationships. In real life, our most valuable professional assets are the skills and experience we acquire and the trusted relationships we build. It’s not surprising that business software becomes more productive and valuable when it is built over these services.

How can I start developing for the LinkedIn Platform today?

Registering as a LinkedIn developer is as simple as filling out a form on developer.linkedin.com. The LinkedIn platform leverages the open OAuth standard to make integrations from almost any language and development environment as simple as possible.

What a breath of fresh air. We were able to go to http://developer.linkedin.com, request a key, and actually write functioning code in less than 15 minutes. It’s amazing to have access to such a powerful platform on tap at any time.

Iain Dodsworth, Founder and CEO of TweetDeck

A number of developers who have helped provide us with feedback and guidance in our development will be announcing integrations in the coming weeks. For example, TweetDeck is announcing full support for the LinkedIn platform in its next version. Now you can easily view or take action on your LinkedIn network updates from within TweetDeck, with the full integration of the LinkedIn profile information of the person who posted the update.

This is the beginning of a new set of opportunities for the LinkedIn platform, and we look forward to seeing the integrations that developers will launch in the coming weeks and months.

Stay tuned for additional enhancements over during the coming months as we learn and grow this platform together.
