Bring the list of posts LinkedIn will not give you.
LinkedIn's analytics API will measure any post you name, but it cannot tell anyone which posts you published. That is a closed permission on LinkedIn's side. So the post list has to come from somewhere that already has it, and these are the somewheres.
