Lazada TH Product Monitor

Scrape product details — title, current price, currency, stock status, brand, seller ID, variant flag, images — from Lazada Thailand product URLs.

What you get

Each product URL returns one JSON record. This is a real record from an actual run, not an illustration:

{
  "url": "https://www.lazada.co.th/products/pdp-i736078-s848857.html",
  "title": "HI-Q 1PLUS PLAIN STAGE 3 2750G.",
  "price": 1359,
  "currency": "THB",
  "currencySign": "฿",
  "brand": "Hi-Q(ไฮคิว)",
  "brandUrl": "https://www.lazada.co.th/hiq/",
  "canonicalUrl": "https://www.lazada.co.th/products/hi-q-1plus-plain-stage-3-2750g-i736078-s848857.html",
  "itemId": "736078",
  "skuId": "848857",
  "sellerId": "1051",
  "categoryId": "4139",
  "inStock": true,
  "quantityMin": 1,
  "quantityMax": 5,
  "hasVariants": true,
  "imageUrls": ["https://th-test-11.slatic.net/p/35c81f7d5be8feac5ae8abe7e65b375a.jpg"],
  "scrapedAt": "2026-08-18T04:45:27.480Z"
}

Use cases

• Price tracking — schedule daily runs to monitor price changes across competitors' SKUs
• Stock monitoring — get notified when a product goes out of stock
• Multi-seller comparison — same product across different Lazada sellers, keyed on sellerId
• Dropshipping intel — verify Lazada TH price + availability before listing on overseas marketplaces

Input

Field	Type	Required	Description
productUrls	string[]	yes	Lazada TH product URLs (https://www.lazada.co.th/products/<slug>.html)
maxConcurrency	int	no	Parallel pages, default 2, max 5
proxyCountry	enum	no	Residential proxy routing, default TH

Limitations (v1)

Read this before subscribing — these are hard limits of what Lazada TH serves, not roadmap gaps.

Not returned, because the data is not in the server-rendered page at all:

• rating / reviewCount — injected by a client-side API call that does not complete in a headless browser
• originalPrice / discountPercent — only the current selling price is present; there is no strikethrough price in the payload
• sellerName — served empty by Lazada; use sellerId to key sellers instead

Other limits:

• Product detail URLs only — not category, search, or seller-shop URLs
• First-listed variant only — products with variants flag hasVariants: true but only the default variant is captured
• No built-in price history (each run is a snapshot; combine with scheduled runs for trends)
• Login-gated content not supported

How it works

Lazada TH server-renders a JSON payload into the page and then hydrates it client-side. The hydration step does not complete under headless Chromium, so anything that only appears post-hydration (ratings, reviews, discount) is unavailable.

This actor reads the server-rendered payload instead:

1. Load the product page through a residential proxy, with a session warm-up on the homepage first
2. Wait for the SSR payload (fields.product + fields.tracking) — not for hydration, which never finishes
3. Extract structured fields from that payload, with a DOM-selector fallback
4. Push one record per URL to the dataset
