Use cases

• Lead generation — Find everyone who engaged with a competitor's or thought leader's post
• Community analysis — Understand who your post resonates with
• Recruiting — Identify professionals who reacted to industry content
• Market research — Discover interested buyers for specific topics
• Influencer outreach — Build contact lists of engaged LinkedIn users

Notes

• LinkedIn limits visible reactors to approximately 1,000 per post (regardless of total shown)
• A valid LinkedIn session cookie (li_at) is required — the scraper cannot work without authentication
• Residential proxy is recommended but not required for small runs
• Rate limiting is handled automatically with exponential backoff

FAQ

How many reactors can I scrape per post? LinkedIn's API exposes up to approximately 1,000 reactors. The actor stops when it reaches the LinkedIn-reported total or your configured maxReactorsPerPost limit.

Do I need a LinkedIn Premium account? No. A standard LinkedIn account with a valid session cookie is sufficient.

Will LinkedIn detect this scraper? The actor uses LinkedIn's own internal Voyager API, the same API that powers the LinkedIn web app. However, excessive scraping or very high rate requests may trigger rate limiting. The actor automatically backs off when rate limited.

Can I filter by reaction type? Yes. Use the reactionTypeFilter input to include only specific reaction types (e.g., only like and insightful). Leave it empty to get all reaction types.

How fresh is the data? Data is fetched live from LinkedIn at run time, so it reflects the current state of reactions on the post.
