❓ Frequently Asked Questions (FAQ)

Does this work on all Shopify stores?

Yes, it automatically detects Shopify endpoints and extracts full catalog data with variant IDs, prices, compare-at prices, discount percentages, and inventory availability. For non-Shopify stores, it falls back to Schema.org/JSON-LD microdata parsing.

How does pagination handle 1,000+ products?

The actor requests 250 items per batch using official catalog endpoints, with built-in polite pacing and automated 429 rate-limit backoff, ensuring complete catalogs up to 5,000 items are scraped reliably.

Can I monitor inventory stock daily?

Yes! Set up a recurring Apify Schedule to run this actor daily or weekly and receive email or webhook alerts whenever prices drop or items go out of stock.
