LinkedIn Hashtag Posts Scraper

Scrape posts tagged with any LinkedIn hashtag (e.g. #AI, #marketing, #python). Returns post content, author information, and engagement metrics for each post.

Cookie is optional — public hashtag pages work without authentication, but providing a LinkedIn session cookie unlocks significantly more results and higher pagination limits.

Features

• Scrape posts for one or more hashtags in a single run
• Accepts hashtags in any format: #AI, AI, artificial-intelligence
• Returns author name, headline, profile URL, post content, media type, and full engagement counts
• Optional LinkedIn cookie for higher result volumes (Voyager API mode)
• Automatic fallback to public HTML mode when no cookie is supplied
• Handles rate limiting with automatic retries and exponential backoff
• Proxy support via Apify proxy configuration

Cookie vs. Public Mode

Mode	Cookie	Results Volume	Notes
Voyager API	Required	Up to 500 posts per hashtag	Uses authenticated LinkedIn API
Public HTML	Not needed	Limited (typically 10-20 per hashtag)	Parses embedded SSR JSON from public page

For best results, provide a valid LinkedIn cookie.

FAQ

Do I need to log in to LinkedIn? No — the actor works without a cookie by scraping the public hashtag page. However, results will be limited. For full scraping capability, provide your li_at cookie.

How do I get my LinkedIn cookie?

1. Log in to LinkedIn in your browser
2. Open DevTools (F12) → Application → Cookies → www.linkedin.com
3. Copy the value of the li_at cookie

Will this get my account banned? The actor uses LinkedIn's official Voyager API with realistic request rates and delays. We recommend using residential proxies for higher volumes to reduce risk.

How many posts can I scrape per hashtag? With a cookie: up to 500. Without a cookie: typically 10-20 posts from the public page.

What hashtag formats does the actor accept? #AI, AI, #machine-learning, machine-learning — all are normalized automatically.

Why are some fields missing from some posts? The actor only includes fields that can be reliably populated. Posts with missing author headlines or media types will omit those optional fields.

Can I scrape multiple hashtags at once? Yes — provide a list in the hashtags field: ["AI", "marketing", "python"].
