This workflow automates high-frequency price tracking across e-commerce platforms. It combines the data-handling power of the Decodo node with the intelligence of Google Gemini to eliminate manual price checks. It is for businesses seeking real-time market intelligence.
Benefits

  1. Total Automation: Handles data sourcing, and email notifications without human help.
  2. Intelligent Extraction: Uses AI to analyze the full page content.
  3. Precision Alerting: Triggers notifications when a product's price meets or falls below the "Desired Price."
  4. Scalable Architecture: Processes large batches of products.

How It Works

  1. Scheduled Data Retrieval: The Schedule Trigger pulls a list of URLs and target prices from Google Sheets.
  2. Raw Data Processing: Data flows through a Decodo node.
  3. Full-Body Extraction: The workflow captures the entire body of the webpage.
  4. AI-Driven Analysis: An AI Agent, powered by Google Gemini, analyzes the text to identify the product name and price.
  5. Regex Data Cleaning: A JavaScript node uses Regular Expressions to sanitize the AI's response.
  6. Smart Comparison & Alerting: An If Node compares the live price against the "Desired Price." If the condition is met, an automated alert is sent via Gmail.

Requirements

  1. n8n Instance
  2. Google Account
  3. Google Gemini API Key
