Amazon Reviews Scraper — New Review Monitor

Returns only new Amazon reviews since last run. Input ASINs + marketplace.

This is an amazon review scraper built for competitor monitoring, 1-star VOC / Facebook ad copy, and n8n / Clay schedules. It is not Helium 10. It is not Seller Central. If the ASINs are yours, use those tools. If the ASINs are a competitor’s, this Actor is the job.

What Amazon actually gives you in 2026

/product-reviews/{ASIN} redirects anonymous traffic to Amazon Sign-In. That is not a selector bug. Stealth Playwright does not unlock it.

Cookieless, this Actor reads the inline reviews on the product page (/dp/{ASIN}): typically 8–13 featured reviews, no pagination.

In July 2026 amazon.com started emptying that inline block too (“Customer reviews require account verification”). amazon.ca and amazon.com.br still render it. Default countryFallback retries US → CA → BR. Rows keep sourceMarketplace so you know which host was parsed.

Optional amazonCookies (throwaway account, Cookie request header) unlocks paginated /product-reviews/ — about 100 reviews per star filter. Expired cookies fail the run.

Why this is not another dump scraper

Junglee, Axesso, and a thousand clones return the same rows every Monday and bill you for the 80 you already have.

	Dump scrapers	This Actor
State	You pass a cutoff date every run	Named KV store of seen review IDs per ASIN + marketplace
Charge	Per review returned	PPE: ASIN check + new reviews (dump/backfill still available)
Sort	Helpful / mixed	Always recent when paginating; product-page pack is Amazon’s featured mix
1-star VOC	Buried filter	oneStarPack mode: 1–2 star, last 30 days, images on
Blocks	Empty 200s	CAPTCHA / unreadable pages fail the run
US wall	Pretend 100 reviews	Fallback CA/BR, honest sourceMarketplace

Modes

• monitor — Weekly competitor job. Bill new-review after the first run.
• dump — Research / first-run backfill. Bill every row as dump-review. Still records IDs so you can switch to monitor later.
• oneStarPack — 1-star + 2-star, last 30 days (unless you set daysBack), images on. Cookieless this filters the 8–13 featured reviews (expect few 1-stars). Cookie mode hits Amazon’s star filter.

First time an ASIN is seen in monitor/oneStarPack:

• firstRunMode=backfill (default) — you get the reviews and pay dump price once.
• firstRunMode=seed — we only remember IDs. Next schedule is a true delta.

Input

Field	Default	Notes
asins	required	ASIN or /dp/ / /product-reviews/ URL
marketplace	US	US, IN, DE, UK, CA, BR
mode	dump	dump is QA-safe and matches Store “scraper” traffic
countryFallback	true	US → CA → BR when the inline block is empty
amazonCookies	empty	Optional. Paginated reviews. Throwaway account only.
maxReviewsPerAsin	20	Cookieless: you will not get more than Amazon’s inline pack
maxPages	2	Cookie mode only
daysBack	0	oneStarPack uses 30 if 0
failOnBlock	true	Keep on
stateStoreName	amazon-reviews-monitor-state	Lives in your account across schedules
proxyConfiguration	Apify proxy	Defaults to residential, country-matched to the host we hit

Output (Junglee-shaped + monitor fields)

reviewId, productAsin / asin, ratingScore / rating, reviewTitle / title, reviewDescription / text, date, verified, reviewerName / name, helpfulCount, imageUrls / images, reviewUrl, variant, vine

Monitor extras: isNew, seenAt, histogram, histogramDelta, daysAgo, hasImages, marketplace, sourceMarketplace, source (product-page or reviews-list), fallbackUsed, mode

Key-value SUMMARY: per-ASIN counts, billed new vs dump, 1–2 star alerts.

Dataset views: All reviews, New only, 1–2 star, With images.

Pricing

Platform usage (Playwright + residential) is included in the event price. You are not billed extra compute on top.

Event	Price	When
asin-checked	$0.08	Every ASIN, even if 0 new reviews
new-review	$0.004 ($4 / 1k)	Monitor delta
dump-review	$0.005 ($5 / 1k)	Dump + first-run backfill
Actor start	$0.00005	Ignore

Dump sticker is above Junglee because compute is included. Weekly monitor is still cheap: check fee + new rows only.

Do not put a $0.30 start fee.

How to schedule

1. Run once in dump or monitor backfill on 1–5 competitor ASINs.
2. Create an Apify Schedule (weekly Monday is the default job).
3. Same stateStoreName. Same account.
4. Optional webhook on successful run → Slack / Make / your app. Filter dataset isNew === true and ratingScore <= 2.

n8n / Clay

• n8n: published-tasks and n8n/amazon-reviews-monitor.json — Apify node, dataset → GPT pain points → Meta ads is the Bright Data-shaped workflow with this scrape node instead.
• Clay: paste ASINs, map isNew, reviewDescription, imageUrls, ratingScore.

Limits (read this)

• Cookieless = product-page inline block, ~8–13 reviews, not 100.
• amazon.com may return zero inline reviews; fallback is CA then BR.
• Cookie mode can hit ~100/star and can get the account restricted. Throwaway only.
• Amazon blocks datacenter IPs. Use residential proxies.
• Review dates are parsed from Amazon’s locale strings; a few formats may have date=null (row still kept).
• Star histogram is Amazon’s percent bars, not absolute counts. Delta is percentage-point change vs last run.
