I\'m trying to figure out how to access any company profile on LinkedIn. For example, the REST endpoint API for LinkedIn itself is:
https://api.link
It looks like they turned that feature off.
See https://developer.linkedin.com/support/developer-program-transition
New requirement for Companies API
All calls to Companies API endpoints will require the authenticated user to be flagged as an administrator of the LinkedIn Company Page that is the target of the API call. You become the administrator of a page when you create it. If the page already exists, you will have to contact the existing administrator to grant admin access to other LinkedIn members.
Your API call will return a 403 Forbidden error if you do not have the appropriate admin permission to interact with the target company.
And in the first line,
On February 12th 2015 we announced a series of changes to our developer program. These changes have now begun to take affect and will be rolled out to the entire LinkedIn application base between May 12th - May 19th, 2015.
So we are out of luck.
