Reply to LinkedIn comment

postUrl requiredLinkedIn post permalink (/feed/update/urn:li:activity:.../).
commentUrn requiredThe target comment's urn, e.g. urn:li:comment:(activity:123,456) (from get_post_comments / comment_post).

replyUrn optionalurn:li:comment of the CREATED reply, from the create response; null if unresolved. Points at the pre-existing reply instead when already_present is true.
