LinkedIn Commenter Extractor

Extract names, titles, companies, LinkedIn URLs, and comment text from people who commented on specific LinkedIn posts. Uses Apify — no LinkedIn cookies required.

Quick Start

Requires requests and APIFY_API_TOKEN environment variable.

# Extract commenters from a single post
python3 skills/linkedin-commenter-extractor/scripts/extract_commenters.py \
  --post-url "https://www.linkedin.com/posts/someone_topic-activity-123456789"

# Multiple posts
python3 skills/linkedin-commenter-extractor/scripts/extract_commenters.py \
  --post-url URL1 --post-url URL2

# Limit comments per post
python3 skills/linkedin-commenter-extractor/scripts/extract_commenters.py \
  --post-url URL --max-comments 50

# Output formats
python3 skills/linkedin-commenter-extractor/scripts/extract_commenters.py --post-url URL --output json
python3 skills/linkedin-commenter-extractor/scripts/extract_commenters.py --post-url URL --output csv
python3 skills/linkedin-commenter-extractor/scripts/extract_commenters.py --post-url URL --output summary

# Deduplicate across multiple posts
python3 skills/linkedin-commenter-extractor/scripts/extract_commenters.py \
  --post-url URL1 --post-url URL2 --dedup

How It Works

1. Takes one or more LinkedIn post URLs
2. Calls the harvestapi~linkedin-post-comments Apify actor (no cookies needed)
3. Extracts commenter name, headline (title + company), LinkedIn profile URL, and comment text
4. Parses headline into separate title and company fields where possible
5. Optionally deduplicates across multiple posts by LinkedIn profile URL
