Product ID Mapper — EAN to ASIN, Google, idealo & Bol IDs

Map EAN, GTIN and UPC barcodes to marketplace product IDs: EAN to ASIN for Amazon, plus the Google Shopping catalog ID, the idealo product ID and the Bol product ID, each with its product URL. One GTIN lookup or UPC lookup covers all four marketplaces at once.

It works in 8 European countries, with up to 50 barcodes per run.

What it does

Most product data starts with a barcode, but each marketplace has its own product ID: Amazon uses the ASIN, idealo and Bol have numeric product IDs, Google Shopping has a catalog ID. This Actor looks up every barcode on the marketplaces you pick and returns one row per barcode with:

• the product ID on each marketplace
• the product URL and the product name as that marketplace shows it
• matches: on how many marketplaces an ID was found

All marketplaces are queried at the same time, one job per marketplace, so a list of 50 barcodes on four marketplaces is still one run.

Who it is for

• Sellers expanding to a new marketplace who need the ASIN or Bol ID for each EAN in their catalogue before they can list or match products.
• Price monitoring and repricing tools that track products by marketplace ID and need a reliable starting mapping.
• Data teams joining sales or ad data from Amazon, Google Shopping, idealo and Bol on one common key, the EAN.
• Anyone cleaning a product feed who wants to know which barcodes are not listed anywhere.

Input

Field	Type	Default	Notes
eans	array of strings	(required)	1 to 50 EAN-13, EAN-8, UPC-12 or GTIN-14 barcodes
country	string	de	de, at, fr, it, es, uk, nl or be
platforms	array of strings	all four	Any of idealo, google_shopping, amazon, bol

Barcodes are trimmed and de-duplicated. Each one is checked for length and check digit; an invalid barcode gets its own free invalid row and is never sent to a marketplace.

Which marketplaces cover which country:

Country	idealo	Google Shopping	Amazon	Bol
de, fr, it, es, uk	yes	yes	yes	no
at	yes	yes	no	no
nl, be	no	yes	yes	yes

A selected marketplace that does not cover the country is marked unsupported and not charged. If none of the selected marketplaces covers it (for example only bol with de), the run stops with an input error.

Input example

{
  "eans": ["4009803341163", "4006381333931"],
  "country": "nl",
  "platforms": ["idealo", "google_shopping", "amazon", "bol"]
}

Output

One row per barcode, in input order.

Field	Meaning
ean, country	The barcode and country
status	found if at least one marketplace found the product, not_found if none did, error if no marketplace could be checked, invalid for a bad barcode
matches	Number of marketplaces that returned a product ID
platforms.amazon.product_id	The ASIN
platforms.google_shopping.product_id	The Google Shopping catalog ID
platforms.idealo.product_id	The idealo product ID
platforms.bol.product_id	The Bol product ID
platforms.<name>.url, .name	Product URL and product name on that marketplace
platforms.<name>.status	found, not_found, error or unsupported
platforms.<name>.errorCode	Why that marketplace failed, if it did
errorCode, error	Why the row failed (invalid_input or internal_error)

Example row for the Netherlands, where idealo is not available (IDs and names are illustrative):

{
  "query": "4009803341163",
  "ean": "4009803341163",
  "country": "nl",
  "status": "found",
  "matches": 3,
  "platforms": {
    "idealo": { "status": "unsupported", "product_id": null, "url": null, "name": null },
    "google_shopping": { "status": "found", "product_id": "6029184473615502", "url": "https://www.google.com/shopping/product/6029184473615502?gl=nl", "name": "Example kitchen scale" },
    "amazon": { "status": "found", "product_id": "B0EXAMPL42", "url": "https://www.amazon.nl/dp/B0EXAMPL42", "name": "Example kitchen scale, stainless steel" },
    "bol": { "status": "found", "product_id": "9300000123456789", "url": "https://www.bol.com/nl/nl/p/example-kitchen-scale/9300000123456789/", "name": "Example kitchen scale" }
  }
}

matches is 3: Google Shopping, Amazon and Bol returned an ID, and idealo was skipped because it does not cover the Netherlands.

Billing

Pay per event. The Pricing tab shows the current rates.

One platform-lookup event is charged for each marketplace that answers found or not_found for a barcode. A not_found answer is a completed lookup, so it is charged as well. In the example above, the row costs three events. Free of charge:

• invalid barcodes
• marketplaces marked unsupported for the country
• marketplace lookups that end in an error or timeout

Rows are written before charging. If your maximum cost per run is reached, you still get every row.

Limits and errors

• 50 barcodes per run, one country per run.
• All marketplaces share an 890-second budget. A marketplace that has not answered by then gives a free timeout error for the barcodes still open. Set the run timeout to at least 960 seconds.
• Each marketplace has its own limit on lookups in progress for your account (idealo 50, Amazon 100, Google Shopping and Bol 1,000). Avoid starting several full runs at the same time.
• One marketplace failing does not affect the others.
• The run always ends as Succeeded. Check status on each row and on each marketplace.

errorCode	Meaning
invalid_input	Not a valid barcode: wrong length, wrong check digit, or one digit repeated
timeout	The marketplace did not answer in time
blocked	The marketplace blocked this lookup
free_limit_reached	Your free Apify plan's allowance for that marketplace is used up
concurrency_limit_reached	Your other runs held all lookup capacity for that marketplace
internal_error	Any other failure

FAQ

How does the EAN to ASIN match work? Amazon is searched for the barcode and the first search result is taken as the match. That is usually the right product, but not always. Compare platforms.amazon.name with your own product name before you rely on the ASIN.

Why is a marketplace found but its product_id null? Google Shopping sometimes lists offers for a barcode without a catalog page. The lookup counts as found, but there is no catalog ID to return, so it does not add to matches.

Does it return prices? No, only IDs, URLs and names. For prices by EAN across marketplaces, use a price comparison Actor.

Can I convert ASINs back to EANs? No. The input must be barcodes.
