LinkedIn Post Comments & Engagements Scraper

Scrape known public LinkedIn post URLs and export post-level engagement metrics plus visible comments to JSON, CSV, Excel, or the Apify API.

This actor is built for GTM teams, agencies, social listening workflows, sales researchers, analysts, and AI agents that already have LinkedIn post URLs and need the people who commented, the text they wrote, and the engagement context around each post.

The actor uses SociaVault's public LinkedIn post endpoint. It does not ask users for LinkedIn cookies, does not access private posts, and does not claim complete LinkedIn-native comment coverage. Output depends on the public data exposed by the provider for each post URL.

What It Extracts

Dataset rows can be post summary rows, comment rows, or both depending on outputMode.

Run Summary

Every run writes OUTPUT and RUN_SUMMARY records to the default key-value store:

{
  "recordsSaved": 101,
  "postsProcessed": 1,
  "commentsSaved": 100,
  "chargedPosts": 1,
  "chargedComments": 100,
  "estimatedPpeCostUsd": 0.61,
  "providerAttempts": 1,
  "providerRetries": 0,
  "providerStatusCodes": [200],
  "stopReason": "finished"
}

Common stopReason values:

• finished - all selected post URLs were processed.
• no-results - provider returned no rows that could be saved.
• provider-error or partial-provider-error - upstream provider failed before or after some records were saved.
• event-limit-reached - Apify PPE charge limit stopped the run.
• invalid-input - input did not include a valid LinkedIn post URL.
• missing-api-key - actor owner has not configured SOCIAVAULT_API_KEY.

Pricing

This actor is designed for pay-per-event monetization:

• apify-actor-start: platform start event.
• post-engagement-scraped: one post-level engagement row saved.
• comment-scraped: one LinkedIn comment row saved.

The actor logs the maximum possible PPE cost before it starts and stops before saving more comment rows than maxPosts * maxCommentsPerPost.

Limitations

This is a known-URL post detail actor, not a LinkedIn keyword search actor. For discovery, use a LinkedIn post search actor first, then feed the discovered post URLs into this actor.

LinkedIn data availability is best-effort. Some posts expose engagement counts but limited or no comments; some post types may not expose every engagement field. The actor does not scrape private LinkedIn content and does not use LinkedIn account cookies.

API Example
