“LinkedIn has examined the value of offering an open API to all developers, and found said program not to be in the company’s best interest. The professional network announced today that it would be restricting broad API use to approved partners only, and restricting open API use to a few simple use cases, including these specified by LinkedIn itself:

-Allowing members to represent their professional identity via their LinkedIn profile using the Profile API.
-Enabling members to post certifications directly to their LinkedIn profile with the Add to Profile tools.
-Enabling members to share professional content to their LinkedIn network from across the Web leveraging the Share API.
-Enabling companies to share professional content to LinkedIn with the Company API.”

This is exactly what twitter started doing in 2012 and is continuing to do now. This means many third party apps will cease to exist or provide Linkedin integration in the way they have been accustomed to.
