Scrape Facebook Posts via Webhook with CoreClaw (n8n)

Scrape public Facebook post data via a simple n8n webhook—normalize it into clean JSON automatically

This n8n workflow exposes a production webhook that accepts one or more public Facebook post URLs, scrapes the posts using CoreClaw, and returns a structured JSON list with normalized post fields like content, author details, timestamps, engagement, and media links.

What this workflow does

• Receives a POST request to the webhook with either a single url or an array of urls.
• Validates and normalizes the incoming URLs into a clean list and records the number of URLs requested.
• Calls the CoreClaw Workers API (Facebook Posts Scraper) with the URL list.
• Normalizes the scraper response into consistent post records, including:
  • Post IDs and author/page details
  • Text content and publish time
  • Engagement metrics
  • Hashtags
  • Image/media links
• Responds with JSON containing: number of input URLs, number of posts parsed, and the normalized post list.

Use cases

• Social content monitoring: scrape specific Facebook posts and keep a structured dataset for analysis or reporting.
• Marketing ops QA: verify public post content, timestamps, and engagement metrics across multiple URLs.
• Competitive research pipelines: feed public Facebook post links into n8n, then store normalized results in your datastore.
• SaaS integrations: let your app call the webhook to retrieve cleaned Facebook post data on demand.

Technical details

• Workflow nodes used: Webhook, Code, HTTP Request, Respond to Webhook, and Sticky Note.
• CoreClaw authentication via n8n environment variable: CORECLAW_API_KEY.
• Configure your client to POST: { "urls": ["https://www.facebook.com/..."] } (or use url).
