📖 Usage Guide

Google Sheet Structure

Your Google Sheet should have the following columns to ensure the workflow functions correctly:

• Product URL (Text): The direct URL to the Google Shopping product page. This is the primary identifier for the product.
• Product Name (Text): The name of the product. This will be automatically populated or updated by the workflow.
• Old Price (Number/Currency): The price of the product from the previous check. This column is crucial for price comparison.
• New Price (Number/Currency): The most recently scraped price of the product.
• Ratings (Number): The star rating of the product.
• Reviews (Number): The total number of reviews for the product.
• Timestamp (Datetime): The date and time when the price check was performed.

Adding Products

• Add Google Shopping URLs to your Google Sheet.
• The workflow will fetch product details and track prices.
• Historical price data builds over time.

Understanding Price Alerts

The default setting for this workflow is to send an email alert when the new price equals the old price. This might seem counterintuitive, but it's useful for specific scenarios, such as:

• Monitoring stable pricing: If you are tracking a product and want to be notified when its price has remained consistent over time, indicating a potential stable buying opportunity or a benchmark.
• Verifying data consistency: To confirm that the scraping process is working correctly and consistently retrieving the same price when no changes are expected.

You can easily customize the alert logic to trigger on different conditions as described below.

Customizing Alert Logic

• Price drops: new_price < old_price
• Significant drops: new_price < (old_price * 0.9) (e.g., price dropped by more than 10%)
• Price increases: new_price > old_price
• Any change: new_price != old_price

Reading the Results

• Real-time pricing data
• Historical tracking
• Product metadata
• Timestamps for each check

🔧 Customization Options

• Add More Data: Descriptions, availability, seller info, shipping, images

• Webhook Integration: Add real-time triggers or Slack alerts
