API Reference/Endpoints

Comment on a post

POST/api/linkedin/gateway/posts/{post_id}/comments

Posts a top-level comment, or, with comment_id set, a reply to an existing comment.

Authentication

Send your personal API key as a bearer token. A missing, malformed or revoked key returns 401.

Path parameters

FieldTypeDescription

post_id *stringThe post's social_id, not necessarily the id visible in its URL.

Body parameters

FieldTypeDescription

account_id *stringA connected account's id.

text *stringUp to 1250 characters.

comment_idstringReply to this existing comment instead of commenting on the post directly.

mentionsarrayLinkedIn only. Entries of { name, profile_id, is_company }.

external_linkstringLinkedIn only. A URL to attach.

as_organizationstringLinkedIn only. Comment on behalf of a company page this account manages.

Response fields

FieldTypeDescription

object"CommentSent"Always this value.

comment_idstringThe id of the comment that was just posted.

Attaching an image to a comment isn't reachable through this JSON route yet — the underlying call takes it as a multipart file upload, which the gateway doesn't forward.
