Scrape Facebook Posts via Webhook with CoreClaw (n8n)

Scrape public Facebook posts in minutes—send URLs to a webhook and get normalized JSON back with CoreClaw

This n8n workflow exposes a webhook that accepts one or more public Facebook post URLs, runs them through the CoreClaw Facebook posts scraper API, and returns consistent, structured post data (content, author/page info, engagement metrics, media links, and timestamps) as JSON.

What this workflow does

• Receives a POST request with either a single url or an array of urls (e.g., { "urls": ["https://www.facebook.com/..."] }).
• Validates and normalizes the incoming Facebook URLs into a clean list, including a URL count and timestamp.
• Calls CoreClaw synchronously by triggering the facebook-posts-scraper worker in the CoreClaw workers API for the provided URLs.
• Parses and normalizes each scraped post into a consistent schema, including:
  • Post URL and ID
  • Author/page details
  • Content
  • Publish time
  • Engagement counts and media links
• Responds to the webhook with a JSON payload containing: number of input URLs, number of scraped posts, and the normalized post records.

Use cases

• Build a Facebook content monitoring tool that turns post URLs into structured data for dashboards.
• Automate social media analytics ingestion for SaaS reporting by storing metrics and timestamps in your database.
• Use webhook-triggered scraping for lead research or brand tracking workflows where users paste post links.

Technical details

• n8n nodes: Webhook, Code, HTTP Request, Respond to Webhook (plus a Sticky Note).
• Authentication: set CORECLAW_API_KEY in n8n environment variables.
• Workflow output: normalized Facebook post records returned directly to the webhook caller as JSON.
