Track competitor prices daily with ZenRows, OpenAI, Telegram, and DataTables

Stop checking competitor prices manually.

This workflow monitors product prices across multiple online retailers every day — automatically. The moment a price changes, you get an instant Telegram alert with the product name, old price, new price, and a direct link to the page.

Set it up once. Let it run forever.

What it does

• Scrapes product pages daily using ZenRows with JS rendering and residential proxies
• Extracts prices via JSON-LD structured data — works across most major retailers
• Compares each price against the last known value stored in an n8n DataTable
• Tracks full price history for every product over time
• Sends an AI-written summary alert via Telegram only when prices actually change
• Updates all records automatically — no manual database management

What's inside

• Ready-to-import n8n workflow (14 nodes, fully documented with sticky notes)
• Full setup guide — step by step from zero to running in ~15 minutes
• DataTable schema template for instant import
• Sample Amazon product URLs to test immediately after setup

What you need

• n8n (self-hosted or cloud)
• ZenRows API key (web scraping)
• OpenAI API key (alert generation)
• Telegram Bot token

Who it's for

Perfect for e-commerce store owners, small businesses, and anyone who needs to stay on top of competitor pricing without lifting a finger.

P.S. I actually use this workflow myself to monitor the price of a tablet I want to buy. I simply pasted the product URLs from a few local retailers and now every morning,if any price changed overnight, I get a Telegram message. That's it. No app, no subscription(only Open Ai, zenrows have free tier), no manual checking.
