LinkedIn Rest API, State token doesn't match

Issue

I am referring this to authorize, authenticate and login to LinkedIn account using Rest API, but now i am facing problem, the WebView where i am displaying the LinkedIn Rest API call url view, is returning blank with message as "State token doesn't match"

It was working fine earlier, but now its returning blank view.

What might be the solution to this? Thanks and help appreciated.

Solution

LinkedIn locked many parts of its APIs on May 12, 2015 according to https://developer.linkedin.com/blog/posts/2015/developer-program-changes

What you're trying to do probably cannot be done anymore following their new API updates.
