According to posts on the LinkedIn Developer forums, this functionality is not exposed by their API.

However, there is an undocumented method which seems to work. Naturally, it may have an oversight on their part to have left it open for use and making of use this naturally comes with the warning since it is undocumented, it may or may not change. If it does change, it may break the functionality of your app
With that said, the suggestion from one of LinkedIn's employee here: https://developer.linkedin.com/comment/3614#comment-3614 has disclosed the above undocumented feature.

Good luck and hopefully, LinkedIn will make such a feature (simple and somehow, still ignored) available via their API.
