LinkedIn Engagement Scraper — Cookie-Based (Client Account)

📌 Service Overview

This actor extracts likers and commenters from a LinkedIn post, providing valuable insights for engagement analysis, audience research, and lead generation.

This actor requires the customer’s own LinkedIn cookies to authenticate. This ensures results from the user’s account context while keeping access under their control.

⚙️ Input Parameters

The service requires the following four required and two optional parameters:

1️⃣ cookie (string, required)

Your LinkedIn session cookies from the same account you want to use.

• Accepted format (cookie header style):
  li_at=...; JSESSIONID="..."; bcookie=...; bscookie=...

How to get it:

1. Install Cookie-Editor (Chrome/Edge)
2. Log into your LinkedIn account
3. Open Cookie-Editor → Export cookies in format (cookie header style)
4. Paste the exported content into this field

🔒 Security: Never share your cookies publicly. Rotate them if you suspect exposure.

2️⃣ url (string, required)

The URL of the LinkedIn post you want to extract engagement from.

"url": "https://www.linkedin.com/feed/update/urn:li:activity:123456789/"

3️⃣ type (string, required, enum: "likes" | "comments")

Choose whether to extract users who liked the post or users who commented.

"type": "likers"

4️⃣ start (integer, optional, default: 0)

Zero-based index from which the scraper will start reading results.

"start": 10

5️⃣ iterations (integer, optional, default: 5)

Number of pagination steps to load (each iteration fetches more results). Allowed range typically 1–15.

"iterations": 3

6️⃣ (Optional) Throttling / Network

• delayMs (integer, default: 2000): Delay in milliseconds between key actions.
• maxConcurrency (integer, default: 1): Maximum parallel tasks.
• proxyCountry (string, default: "auto"): Country code for proxy (e.g., EC, US, ES).

💡 Optional: expose maxItems if you want to stop after a certain number of results.

🔄 How It Works

1. Authenticates to LinkedIn using the provided cookie.
2. Opens the engagement section (likes or comments) for the given url.
3. Extracts profiles from the selected engagement type.
4. Applies pagination and index filtering (start, iterations).
5. Produces structured JSON with fields like name, headline, and profile URL.

⚠️ Rate-Limit & Safety (Read Before Running)

LinkedIn actively protects its platform. Moderate usage is crucial to avoid rate-limits or account restrictions.

Strongly recommended:

• Keep low concurrency (e.g., maxConcurrency: 1–2).
• Add delays between requests (e.g., delayMs: 1500–3000).
• Limit sessions to short windows (don’t run 24/7).
• Avoid opening too many profiles quickly (20–40/hour is a safe ballpark; adapt to your account’s history).
• Use an IP/location consistent with your account’s usual login (proxy close to your region).
• Don’t switch cookies/IPs frequently.
• Do not run from multiple locations at the same time.

If you get 401/403/999 → cookie expired/invalid or access blocked.
If you get 429 → you hit rate limits → increase delays / reduce iterations.

🔐 Compliance & Ethics

• Use only your own account/cookies or accounts you’re authorized to operate.
• Respect LinkedIn’s Terms of Service and applicable privacy laws (GDPR/PII).
• Scrape only what you’re allowed to access; store data securely and responsibly.
