Comment on LinkedIn Post
Comment on a LinkedIn post with up to 1250 characters, either as a top-level comment or as a reply to a specific comment using a parent comment ID. A safety limit of 100 comments per day keeps your engagement looking natural. The call fails if the post ID is invalid or the post was deleted.
