Create a comment or reply (multi-platform)

Post a comment or reply on Instagram, Facebook, YouTube, LinkedIn or TikTok. Provide exactly one of comment_id (reply to that comment), post_id or post_url (top-level comment). Instagram supports replies only, so comment_id is required. For LinkedIn, post_id is the post URN. On TikTok, post_id (the video id) is always required — adding comment_id on top of it turns the call into a reply — and the connection must report the comments capability, i.e. a reconnected account, or the call answers 400 with error_code tiktok_reconnect_required.
