eBay Demand & Price Band Scoring n8n Workflow (Bright Data, OpenAI, Sheets, Slack)

Automatically score eBay demand and generate weekly sourcing briefs—then notify your team in Slack

This n8n workflow pulls eBay search results via Bright Data, scores each listing by demand within condition-based price bands, summarizes the top opportunities with OpenAI, logs everything to Google Sheets, and posts a ranked digest to Slack—running on a weekly schedule so you never miss new high-signal listings.

What this workflow does

• Runs weekly on a schedule and loads a comma-separated list of eBay search keywords plus scoring and output settings.
• For each keyword, triggers a Bright Data eBay discovery scrape, then polls until the dataset snapshot is ready.
• Downloads listings and computes a demand score per listing by comparing sold count and price against the median within each keyword-and-condition band, incorporating watchers, carts, offers, and remaining stock.
• De-duplicates using Google Sheets: reads previously logged listings, filters out items reported within the last 30 days, and keeps the top N new picks.
• Uses OpenAI to extract structured product details from each selected listing’s title and specifications (brand, model, product type, key features, and whether it’s a bundle), then generates a short sourcing brief from the ranked set.
• Logs results by appending one row per selected listing to Google Sheets and posts a formatted Slack digest including top picks and the sourcing brief.

Use cases

• Weekly monitoring of eBay demand for specific product categories to guide sourcing decisions.
• Automated discovery of high-demand listings within tight price/condition bands.
• Team-friendly reporting for e-commerce operators, SaaS operators, and automation engineers via Slack notifications.
