Key Takeaways
- Works on any LinkedIn post - Personal posts, company posts, articles, and shared content
- Automatic pagination - Loops through up to 50 pages of reactions with 2-second delays
- Extracts profile URLs - Converts reactor profile IDs into LinkedIn profile URLs
- Real-time export - Saves profiles to Google Sheets as each page is processed
- DevTools-based - You paste a fetch() request copied from a post's reactions panel
What This Workflow Does
This workflow takes a LinkedIn reactions API request (copied from DevTools), pages through all reactions on a post, extracts the profile URL of each person who reacted, and saves them to Google Sheets. You pick any LinkedIn post, copy the reactions network request, and get a spreadsheet of everyone who engaged.
Use cases:
- Extract leads from viral posts in your industry
- Build outreach lists from people engaging with competitor content
- Find professionals interested in a specific topic based on their reactions
- Collect engaged audiences from thought leader posts
How It Works
| Step | What Happens |
|---|---|
| 1. Manual trigger | You paste a fetch() request from a post's reactions API |
| 2. Parse request | Code node extracts the URL, headers, CSRF token, and post URN |
| 3. Loop through pages | Fetches each page of reactions (10 per page, 2-second delay) |
| 4. Extract profiles | Code node pulls profile IDs and converts them to LinkedIn URLs |
| 5. Save to Google Sheets | Claude Sonnet writes each profile URL and page number to your sheet |
The loop runs up to 50 pages of 10 reactions each.

FAQ
Q: Does this work on any LinkedIn post? A: Yes. Personal posts, company page posts, articles, and shared content all work.
Q: Why do I need to click the reactions count first? A: Clicking the reactions count opens the reactions panel and triggers the API request in your browser's network tab. That is the request you need to copy.
Q: What if the post has fewer reactions than expected? A: The workflow stops automatically when there are no more reactions to fetch. It processes whatever is available.
Q: Can I filter by reaction type (like, celebrate, etc.)? A: The default workflow extracts all reaction types. You can modify the code nodes to filter by specific reaction types.
