Google Shopping Price Drop Alerts to Telegram (n8n + SearchApi)

Get notified on Google Shopping price drops—automatically sent to Telegram

This n8n workflow checks your wishlist on a daily basis using SearchApi Google Shopping, detects when an item’s lowest new-item price drops compared to what you previously saved, and sends a single consolidated alert to Telegram only when there’s something worth seeing.

What this workflow does

• Runs daily on a schedule to keep your watchlist up to date.
• Loads your wishlist, location, and drop threshold, then retrieves previously saved prices from an n8n Data Table (“Price Watch”).
• Splits the wishlist into individual product searches and queries SearchApi for Google Shopping offers per item.
• Selects the lowest valid “new” offer for each product and compares it against:
  • the last saved price, and
  • optional configured target prices (e.g., product=targetPrice in Settings).
• Builds one HTML Telegram message containing only products with a detected drop (and stops if there are no alerts).
• Sends the alert to your Telegram chat and upserts the latest prices back into the Data Table for the next run.

Use cases

• Track high-consideration purchases (electronics, home gear, accessories) and buy when Google Shopping hits your target.
• Monitor multiple vendors from one place without manually checking price history.
• Set “drop threshold” rules to avoid spam and only notify when savings are meaningful.

Technical details

• SearchApi integration via the community node @searchapi/n8n-nodes-searchapi (requires SearchApi API key credential).
• n8n Data Table named Price Watch to store product, last_price, currency, seller, url, and checked_at.
• Telegram node to send alerts to your configured bot/chat ID.
• Typical workflow nodes: set, code, filter, telegram, data table, and sticky note.
