Shopify Price Monitoring API: Track Prices Without Scraping

2026-03-07 · ShelfRun Team

Why Monitor Shopify Prices?

With over 4.4 million Shopify stores worldwide, price monitoring is essential for competitive intelligence. Whether you're a retailer tracking competitors, a dropshipper monitoring suppliers, or a consumer app building price alerts, you need reliable, structured price data.

Traditional web scraping breaks constantly — Shopify updates their templates, rate limits your requests, or blocks your IP. ShelfRun's API abstracts all of this away. One API call gets you every product, every price, every variant.

Quick Start: Monitor a Shopify Store

curl -X POST https://shelfrun.com/v1/quickscan   -H "Content-Type: application/json"   -H "X-API-Key: YOUR_KEY"   -d '{"url": "https://allbirds.com"}'

That's it. You get back structured JSON with every product: name, price, currency, stock status, images, and variants. No Puppeteer. No Playwright. No proxy rotation.

Set Up Price Change Alerts

ShelfRun's webhook system notifies you instantly when prices change. Configure a webhook URL for any store, and you'll receive payloads with the exact products that changed, their old prices, and new prices.
