I've managed thus far to get the auth code and exchange it to an access token.
Now I only need to know what I do with it (which request I need to send/ or where) so I can post to a group (and if I have the group name, how do I obtain the group id?)
Specifically, I want to know how to use the REST api in C# to post to a specific group via a request.
Can anybody confirm the answer below?
LinkedIn does not presently expose Groups-related APIs, so this will not be possible.
