WooCommerce Catalog Monitor

Track any WooCommerce store's catalog over time: new products, removed products, price changes, and stock flips — read from the store's public WooCommerce Store API. No scraping, no browser, no proxies, nothing to break when a site redesigns.

Run it once to record a baseline, then schedule it (daily, hourly — your call). Every scheduled run diffs the live catalog against the last snapshot and pushes one row per change. The first run for a store never charges for changes.

What it monitors

Change type	Meaning
new	Product appeared in the catalog
removed	Product disappeared from the catalog
price_changed	Price (or currency) changed — old and new values included
stock_changed	Stock status flipped (e.g. instock → outofstock)

Each change row carries the product name, SKU, permalink, prices, stock status, and detection timestamp. Every run also writes a store-summary row per store with counts.

Pricing — pay per event, no subscription

Event	Price
Run started	$0.001 per run
Product checked	$0.0002 per product read ($0.20 per 1,000)
Change detected	$0.005 per new / removed / price-changed / stock-flipped product

Typical run: a 1,000-product store with 10 changes costs about $0.25 ($0.001 run + $0.20 products + $0.05 changes).

Failed stores (no public Store API, private/B2B, network errors) return an error row and are not charged. Set Maximum charge per run and the actor stops cleanly before exceeding it.

Example input

{
  "storeUrls": ["https://your-store.com"],
  "maxProductsPerStore": 1000,
  "outputMode": "changes",
  "stateName": "woo-catalog-monitor",
  "maxChargeUsd": 5
}

Example output (one row per change)

Prices are in the store currency's minor units (e.g. cents), exactly as the Store API returns them.

{
  "recordType": "change",
  "store": "https://your-store.com",
  "storeUrl": "https://your-store.com",
  "productId": "1234",
  "changeType": "price_changed",
  "name": "Ceramic Mug - 12oz",
  "sku": "MUG-12",
  "price": 1650,
  "regular_price": 1650,
  "sale_price": 1650,
  "oldPrice": 1400,
  "currency": "USD",
  "oldCurrency": "USD",
  "stock_status": "instock",
  "is_in_stock": true,
  "permalink": "https://your-store.com/product/ceramic-mug-12oz",
  "detectedAt": "2026-10-16T09:00:00+00:00"
}

Input

• Store URLs — one or more WooCommerce store URLs, e.g. https://competitor-store.com.
• Max products per store (default 1,000) — caps catalog reads and your per-run cost.
• Output mode — Changes only (one row per change; best for monitoring) or Full catalog snapshot (every product).
• Snapshot store name — the named key-value store holding baselines. Keep it constant across scheduled runs; change it to start a fresh baseline.
• Maximum charge per run (USD) (default $5) — hard spending cap.

Requirements and limits

• The store must expose the public WooCommerce Store API (/wp-json/wc/store/v1/products). The vast majority of WooCommerce stores do — it's on by default. Private, password-protected, and B2B stores are reported as unsupported, not charged.
• Prices come from the store's own API in its own currency.
• Polite by design: sequential requests, small delays between pages.

Use it from code

curl -X POST "https://api.apify.com/v2/acts/dheerajitbhu~woocommerce-catalog-monitor/run-sync-get-dataset-items" \
  -H "Authorization: Bearer $APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"storeUrls": ["https://competitor-store.com"], "outputMode": "changes"}'

from apify_client import ApifyClient
client = ApifyClient("YOUR_API_TOKEN")
run = client.actor("dheerajitbhu/woocommerce-catalog-monitor").call(run_input={
    "storeUrls": ["https://competitor-store.com"],
    "outputMode": "changes",
})
for row in client.dataset(run["defaultDatasetId"]).iterate_items():
    if row.get("recordType") == "change":
        print(row["changeType"], row["name"], row.get("permalink"))

Schedule it in Apify with a daily (or hourly) schedule and a fixed snapshot store name — each run then reports only what changed since the last one.
