eBay Listing Webhook Automation with CoreClaw (n8n)

Webhook-to-JSON eBay Listing Scraping with CoreClaw (n8n)

Turn any eBay keyword search into a clean, structured JSON response. This n8n workflow exposes a webhook that accepts one or more search keywords, runs the CoreClaw eBay Data Scraper, normalizes key listing fields, and returns product-ready data for your downstream automations.

What this workflow does

1. Receives a POST webhook request containing either a single keyword ({"keyword":"gaming laptop"}) or a keyword array ({"keywords":["gaming laptop"]}).
2. Validates and formats keywords into a clean array, including a count and timestamp.
3. Calls the CoreClaw eBay Data Scraper worker via an authenticated HTTP request using your CORECLAW_API_KEY.
4. Normalizes eBay listing data into consistent product records, including:
   • URL, title, price, condition
   • Seller and shipping
   • Reviews, return policy
   • Image
5. Responds with JSON including the input keyword count, product count, and the normalized products array.

Use cases

• Price monitoring: Trigger scraping from your app whenever users enter eBay search terms, then store results for comparison.
• Inventory sourcing: Fetch normalized eBay listing fields (price, shipping, seller, condition) to support procurement workflows.
• Analytics pipelines: Feed structured listing data into dashboards or data stores without manual formatting.
• Automation engineering: Use the webhook as a reliable “scrape endpoint” for multiple downstream n8n workflows.

Technical details

• Webhook node: “ebay-product-scraper” endpoint for POST requests.
• Code node: keyword validation/formatting and normalization logic.
• HTTP Request node: sends keywords to the CoreClaw eBay Data Scraper worker (authenticated).
• Respond to Webhook: returns a structured JSON payload.
• Environment variable: set CORECLAW_API_KEY in n8n for authentication.

SEO note: Ideal as an eBay listing webhook automation workflow for n8n users who need CoreClaw-based eBay data scraping delivered as clean JSON.
