Website Compatibility Notes

Shopify stores vary in protection level. Most product pages are accessible with basic rendering. The /products.json endpoint often provides structured data directly.

Frequently Asked Questions

How do I extract product data from Shopify stores?

Many Shopify stores expose a /products.json endpoint with structured product data. Alternatively, send any Shopify product page URL to AlterLab for full HTML rendering with product details, variants, and pricing.

Can I extract inventory and variant data from Shopify?

Yes. Shopify product pages include variant information (sizes, colors, availability). AlterLab renders the full page to capture all variant details and stock status.

Does AlterLab work with password-protected Shopify stores?

AlterLab is designed for publicly accessible data only. Password-protected stores require authentication and are outside the scope of the service. Only use AlterLab for publicly visible storefront pages.
