Shopify Competitor Product Monitor

Monitor public Shopify stores for product, price, promotion, and inventory changes. It uses Shopify's public product JSON endpoint when available and falls back to public product pages. No Shopify API key, store login, or private app is required.

Best use cases

• Competitor price and promotion monitoring
• New-product and assortment discovery
• Stock-out and restock signals
• Scheduled market snapshots for e-commerce analysis

Input

Parameter	Type	Default	Description
storeUrl	string	required	Public Shopify store URL, for example https://www.allbirds.com
maxItems	integer	100	Maximum products to inspect
collection	string	none	Optional collection handle such as frontpage
onlyOnSale	boolean	false	Keep only products with a compare-at price above the current price
includeDescription	boolean	true	Include cleaned product description text
trackChanges	boolean	true	Persist successful product snapshots in a named Apify key-value store
onlyChanges	boolean	false	Emit only first-seen or changed products

Output

Each product includes title, URL, price range, compare-at price, sale status, inventory status, variants, images, tags, and a snapshot_hash.

When change tracking is enabled, the output also includes:

• change_type: new, price_changed, sale_status_changed, inventory_status_changed, available_variant_count_changed, product_content_changed, or unchanged
• change_detected: whether the product changed since the previous successful run
• change_summary: machine-readable reasons for the change
• previous_snapshot_hash and previous_scraped_at

Example output

{
  "status": "ok",
  "title": "Everyday T-Shirt",
  "url": "https://example.com/products/everyday-t-shirt",
  "price_min": 28.0,
  "price_max": 32.0,
  "inventory_status": "in_stock",
  "change_type": "price_changed",
  "change_detected": true,
  "change_summary": ["price_changed"]
}

Limitations

The actor only uses publicly accessible Shopify data. It tries /products.json, then Shopify's public XML product sitemap, then ordinary product pages with JSON-LD. This makes it useful for stores that disable the public product endpoint or use JavaScript-heavy collection pages. If all public paths are blocked, the actor emits a diagnostic status record instead of an empty successful dataset. A private Shopify Admin API is not required.
