Everything You Need for LinkedIn Comment Management

Read and moderate LinkedIn comments without wiring up LinkedIn’s versioned socialActions API. One endpoint for listing, replying, and deleting.

List Comments and Replies

Fetch every comment on a LinkedIn post with author, text, timestamp, like count, and its replies. Pass a comment URN to load its nested replies. Paginate with a cursor.

Reply and Comment

Post a top-level comment on a post, or reply to an existing comment. Switch between a postId and a commentId on the same endpoint.

Person or Organization

PostPeer posts the comment as the connected identity, a member or a company Page, using the right actor URN automatically. No URN juggling on your side.

Delete Comments

Remove a comment from your post by comment URN when you need to clean up spam or abuse. One call.

Works on Existing Posts

Read and moderate comments on any post on the connected account, not only posts you published through PostPeer.

Community Management Handled

PostPeer runs LinkedIn’s Community Management OAuth flow and requests the social-feed scopes comments require. Accounts connected before comment support shipped just reconnect once.
