Comment on LinkedIn post

Post a top-level comment on a LinkedIn post by its permalink. Posts a real public comment under the logged-in account. Only comments on the main post, not a reply thread. Returns the new comment's permalink so you can reply to it afterward.

Input

comment required

The comment text to post. This posts a real, public comment under the user's account immediately, so confirm the exact text with them before running.

postUrl required

LinkedIn post permalink (/feed/update/urn:li:activity:.../ or /posts/...).

mentions optional

Person or organization names to mention, appended in order at the end of comment and resolved through the comment box's own mention typeahead. Confirm each name with the user before running. If a name is ambiguous (several people share it exactly), the run throws and lists the candidates by headline — re-run with the name plus enough of their headline, company or organization for LinkedIn's typeahead to narrow to exactly one match; this works even though the matched suggestion still displays just the plain name.

Default: []

Output

posted required
comment required
postUrl required
account_used required
already_present required
verified_on_page required
commentUrn optional
