1. Open linkedin.com in your browser and log in
2. Open DevTools (F12 or right-click → Inspect)
3. Go to Application → Cookies → https://www.linkedin.com
4. Find the cookie named li_at
5. Copy the Value and paste it into the cookie input field

Option 2: Full browser cookies JSON array

1. Install a browser extension like EditThisCookie or Cookie-Editor
2. Log into LinkedIn
3. Export all cookies as JSON from the extension
4. Paste the full JSON array into the cookie input field

Note: Your cookie is used only for authentication with LinkedIn's API. Never share it publicly. Cookies typically expire after 1 year or when you log out of LinkedIn.

FAQs

How many posts can I scrape per run? Up to 100 posts per run (set via maxResults). LinkedIn's search API returns results in pages of 10.

Why are some engagement counts zero? LinkedIn's search API does not always return engagement data in search result previews. When the socialProofText field is absent from the result, counts default to 0. Use the LinkedIn Post Scraper actor to get full engagement data for specific posts.

Why is post content sometimes truncated? Search results return a content snippet, not the full post text. Long posts are cut off by LinkedIn's search API. To retrieve the full text, visit the post URL directly.

What causes rate limiting? LinkedIn throttles search requests. The actor automatically adds delays between requests (2–5 seconds) and retries on 429 responses. If you need to scrape large volumes, increase the delay by reducing maxResults and running multiple actors.

Do I need a proxy? A proxy is recommended but not required. The actor first tries a residential proxy (best for LinkedIn), then falls back to datacenter proxy, then direct connection. You can also supply a custom proxyConfiguration.

Why does the actor fail with "cookie is invalid or expired"? Your li_at cookie has expired or LinkedIn invalidated the session. Log out and back into LinkedIn, then copy the fresh li_at value.

Can I search posts in other languages? Yes. Enter your search query in any language. LinkedIn returns results in the language of the posts matching your query.

Is logging in or a paid LinkedIn account required? No paid subscription is required. Any standard LinkedIn account works. The li_at session cookie from a free account is sufficient.
