Shopify Real-Time Price Tracker Monitor Shopify store product prices in real-time, track price changes, and get alerts when prices change by a specified percentage. ## Features ✅ Real-time Price Tracking - Monitor product prices across multiple Shopify stores 📊 Price Change Detection - Get notified when prices drop or increase by your threshold 💾 Persistent Storage - Save product URLs and price history between runs 🔄 Scheduled Monitoring - Configure hourly, daily, or weekly checks 📈 Detailed Reports - View comprehensive price change statistics 🎯 Smart Alerts - Only alert on significant price changes (configurable threshold) ## Input Parameters ### Required Fields - Product URLs - List of Shopify product URLs to monitor - Example: https://shop.gymshark.com/products/gymshark-vital-seamless-2-0-leggings-black - Leave empty to use saved URLs from previous run ### Optional Fields - Use Saved Product URLs (default: true) - Reuse URLs from last run without pasting them again - Save Product URLs for Next Run (default: true) - Automatically save URLs for future runs - Check Interval (default: every-6-hours) - Options: hourly, every-6-hours, daily, weekly - Use this setting when scheduling the Actor - Price Change Alert Threshold (default: 5%) - Only alert if price changes by this percentage or more - Range: 0-100% - Maximum Products to Track (default: 10) - Maximum number of products to track per run - Range: 1-100 ## Output The Actor produces a structured dataset with the following fields: - url - Product URL - productTitle - Product name - currentPrice - Current price - previousPrice - Price from last run (if available) - priceChange - Dollar amount change - percentChange - Percentage change - status - One of: - tracked - First time tracking - price_dropped - Price decreased significantly - price_increased - Price increased significantly - no_significant_change - Changed but below threshold - error - Failed to extract price - currency - Currency code (e.g., USD) - timestamp - ISO timestamp - lastChecked - Human-readable date/time ## How It Works 1. Price Extraction - Uses multiple strategies to extract prices: - JSON-LD structured data (most reliable) - Common Shopify CSS selectors (fallback) 2. Price Comparison - Compares current prices with stored historical data 3. Change Detection - Calculates price changes and flags significant movements 4. Data Storage - Saves price history and product URLs for next run 5. Report Generation - Exports results to dataset in table format ## Example Input json { "productUrls": [ {"url": "https://shop.gymshark.com/products/gymshark-vital-seamless-2-0-leggings-black"}, {"url": "https://www.allbirds.com/products/mens-wool-runners"} ], "useSavedProducts": true, "saveProducts": true, "checkInterval": "every-6-hours", "priceChangeThreshold": 5, "maxProducts": 10 } ## Local Development ### Prerequisites - Node.js 20+ - Apify CLI (install: curl -fsSL https://apify.com/install-cli.sh | bash) ### Installation bash cd shopify-price-tracker npm install ### Run Locally bash apify run ### Deploy to Apify Platform bash # Login to Apify apify login # Push to platform apify push ## Best Practices - Respect Rate Limits - The Actor uses concurrency controls and delays - Monitor Responsibly - Don't track too many products at once - Review Terms of Service - Ensure compliance with store policies - Set Realistic Thresholds - 5-10% is good for most use cases - Schedule Wisely - Every 6 hours is sufficient for most price tracking ## Scheduling To run the Actor on a schedule: 1. Deploy to Apify Platform (apify push) 2. Go to Actor Settings → Schedule 3. Create schedule matching your checkInterval setting 4. Enable "Use Saved Products" to avoid re-entering URLs ## Troubleshooting ### No prices extracted - Check if the product page is accessible - Verify the URL is a valid Shopify product page - Some stores may require JavaScript rendering (this Actor uses Cheerio) ### Too many errors - Reduce maxProducts setting - Check proxy configuration - Verify network connectivity ### Missing previous prices - Ensure saveProducts is enabled - Price history builds over multiple runs ## Support For issues, feature requests, or questions: - GitHub Issues: Report an issue - Apify Forum: https://forum.apify.com/ - Documentation: https://docs.apify.com/ ## License ISC License - See LICENSE file for details
