LinkedIn Engagement Scraper

Overview

This actor extracts users who liked or commented on a specific LinkedIn post. It requires your own LinkedIn session cookies for authentication, operating within your account's context. Use it for engagement analysis, audience research, or lead generation.

Key Features

• Cookie-Based Authentication: Uses your provided LinkedIn cookies (li_at, JSESSIONID, etc.) to access data.
• Targeted Scraping: Fetches either likers or commenters from a single post URL.
• Pagination Control: Uses start and iterations parameters to manage data retrieval.
• Rate-Limit Management: Includes configurable delays (delayMs) and concurrency limits (maxConcurrency) to help avoid blocks.
• Structured Output: Returns a clean JSON array with profile URLs, names, and headlines.

How to Use

The actor authenticates with your cookies, navigates to the post's engagement section, and extracts the requested user profiles. It handles pagination automatically based on your input settings.

Important: LinkedIn has strict anti-scraping measures. To maintain account safety:
* Use low concurrency (keep maxConcurrency at 1-2).
* Add sufficient delays between requests (e.g., delayMs: 1500-3000).
* Limit run duration and volume (e.g., ~20-40 profiles per hour as a guideline).
* Use a proxy location consistent with your account's normal login region.
* Do not run the actor from multiple locations simultaneously.

Common HTTP errors:
* 401/403/999: Usually indicates expired or invalid cookies.
* 429: Rate limit hit. Increase your delays and reduce iterations.

Input

Configure the actor with the following input parameters.

Required:
* cookie (string): Your LinkedIn session cookies in header format.
* Format: li_at=...; JSESSIONID="..."; bcookie=...; bscookie=...
* How to get them: Use a browser extension like Cookie-Editor to export cookies after logging into LinkedIn.
* url (string): The full URL of the LinkedIn post to scrape.
* type (string): The engagement type to extract. Must be "likes" or "comments".

Optional:
* start (integer): Zero-based index to start reading results from. Default: 0.
* iterations (integer): Number of pagination steps to load (each fetches more results). Typical range 1-15. Default: 5.
* delayMs (integer): Delay in milliseconds between key actions. Default: 2000.
* maxConcurrency (integer): Maximum parallel tasks. Default: 1.
* proxyCountry (string): Country code for proxy (e.g., "US", "ES"). Default: "auto".

Example Input

{
  "cookie": "li_at=YOUR_TOKEN; JSESSIONID=\"ajax:123...\"; bcookie=...; bscookie=...",
  "url": "https://www.linkedin.com/feed/update/urn:li:activity:123456789/",
  "type": "likes",
  "start": 0,
  "iterations": 5,
  "delayMs": 2000,
  "maxConcurrency": 1,
  "proxyCountry": "auto"
}

Output

The actor outputs an array of objects in JSON format. Each object represents a user profile.

Example Output
