PostComment

A comment on a post, with its author.

Returned byposts.enrichPost.commentsPostComment.replies

Fields #

Field	Type	Notes
`urn`	string	The comment's own numeric id. A comment urn arrives as a nested tuple, urn:li:comment:(activity:<postId>,<commentId>), and this is the comment id from inside it, not the post id.
`url`	string
`text`	string
`commented_at`	string (RFC 3339)	Absent when the date could not be decoded, rather than present and wrong.
`author`	PostAuthor	Deliberately richer than ActivityComment, which is the same word for a different payload: that one is a comment the member left on someone else's post and carries a stub of that post; this one is a comment left on the post you asked for, and carries the commenter instead.
`reaction_count`	integer
`reply_count`	integer	The total count of replies to this comment, which can be higher than what replies carries - only the first is returned inline.
`reactions_by_type`	ReactionCount[]	The breakdown behind reaction_count.
`replies`	PostComment[]	Nested replies, two levels deep. LinkedIn returns the first reply inline; deeper threads are not fetched, because each level is another request.

Absent is not null: a field we did not get is omitted rather than sent as an empty string, so you can tell "LinkedIn does not have this" from "this person left it blank".
