Heureka.sk feed for Shopify

Heureka.sk reads the same SHOPITEM elements as Heureka.cz, but almost everything you put in them is local: euro prices, a Slovak category tree, Slovak carrier codes, Slovak product names and a lower CPC ceiling. Feedflock builds the Heureka.sk feed from your Shopify catalog on its own Slovak template, so a shop already selling in Czechia does not have to fork its data to sell in Slovakia.

CPC rules

Euro bids by rule, under the 50 € ceiling.

On Heureka.sk HEUREKA_CPC is a bid in euro, with a ceiling of 50 € (a different limit from the Czech 1,000 Kč, in the same element). Set it with rules: a condition and a bid, first match wins. A product no rule matches goes out without the element, and a bid over 50 € is flagged before the feed ships.

In the app a rule can test collection, product type, vendor, tag, price, purchase cost or a metafield, and its value can be a fixed amount, a metafield or Liquid, so a bid can follow your margin too.

Feed health

Catch feed issues before Heureka.sk does.

Before every generation Feedflock checks that every field the channel requires is filled, and, on templates verified against the channel's own spec, that the values fit its rules. Most problems are fixed with one click, without editing products in Shopify.

Feed quality · heureka-sk.xml

76 / 100

To review: 4

EAN not in EAN-13 format on 12 variantsHeureka.sk treats any other barcode format as an error, not as a missing value. GTIN-14 and spreadsheet “.0” codes are the usual cause.

PRODUCTNAME without the brand on 6 productsHeureka.sk pairs on the name. MANUFACTURER only feeds the brand filter, so the brand has to be in PRODUCTNAME too.

Product type used as category on 9 productsWithout a mapping, CATEGORYTEXT falls back to your Shopify product type, often a Czech word, instead of a path from the Slovak tree with the Heureka.sk root.

HEUREKA_CPC above 50 € on 2 productsThe Slovak ceiling is 50 €, not the 1,000 of the Czech site. Feedflock reports the bid instead of quietly cutting it.

Setup

Live in five steps

From a bare Shopify store to a listed offer: the whole setup fits into one coffee break.

Open a Heureka.sk shop account
Register the shop in the Slovak Heureka administration. Heureka.sk is a separate listing with its own feed URL, even if you already sell on Heureka.cz.
Install Feedflock
Add Feedflock from the Shopify App Store. It reads your products, variants, stock, shipping settings and, with Shopify Markets, your Slovak prices and translations.
Pick the Heureka.sk template
Not a copy of the Czech one: euro prices, Slovak PARAM names, the Slovak carrier list and a CPC ceiling of 50 €. ITEM_ID, PRODUCTNAME, PRICE_VAT, DELIVERY_DATE and CATEGORYTEXT are mapped from the start.
Map to the Slovak tree
Match your product types to the Heureka.sk category tree. It is a tree of its own, not a translation of the Czech one, and CATEGORYTEXT goes out with the Heureka.sk root.
Paste the feed URL
Copy the hosted URL into your Heureka.sk administration. Feedflock regenerates the file on your schedule, as often as every hour.

Product cards for the Slovak market

Heureka.sk pairs offers from different shops onto one product card by PRODUCTNAME and EAN. Slovak shoppers compare your euro price, dispatch time and shipping right next to everyone else's.

The format you already know

Heureka.sk uses the same 26-element SHOPITEM vocabulary as Heureka.cz. If you list in Czechia, the Slovak feed is a second template on the same catalog, not a new data structure.

Reviews that follow your products

Overené zákazníkmi product reviews are tied to ITEM_ID. Feedflock uses the Shopify variant ID, which never changes and is never reused, so reviews stay with the right product.

The feed

A separate Heureka.sk template, not a translated copy: euro prices, Slovak PARAM names (Veľkosť, Farba), the Slovak category tree and the 50 € CPC ceiling
All 47 Heureka.sk carrier codes, from SLOVENSKA_POSTA and PACKETA_DOMOV to SPS and WEDO_BOX; cash on delivery goes out as the full total
With Shopify Markets, PRICE_VAT carries your Slovak euro prices and names come from your Slovak translations
PRODUCTNAME built from product and variant title, with a warning for every name that is missing the brand Heureka pairs on
Spec limits checked at generation, from EAN-13 and the 36-character ITEM_ID to the 50 € CPC ceiling, reported and never silently rewritten
Sold-out variants left out by default and DELIVERY_DATE derived from Shopify availability
Fetch tracking shows when Heureka.sk last downloaded the feed and alerts you if it stops

Deep dive

Same elements, local content

The same SHOPITEM vocabulary as Heureka.cz: ITEM_ID, PRODUCTNAME, PRICE_VAT, DELIVERY_DATE, CATEGORYTEXT, DELIVERY
Prices in euro incl. VAT, the VAT rate as a percentage (23 % standard)
Slovak product names and PARAM names, the Slovak category tree
A CPC ceiling of 50 € instead of 1,000 Kč

Technical details

Heureka publishes the same element list on both sites, so the structure of a Heureka.sk feed is the one you know from Czechia: one SHOPITEM per variant, PRODUCTNAME as the pairing key, DELIVERY_DATE in days to dispatch, DELIVERY blocks with carrier codes.

What changes is the content. PRICE_VAT is in euro incl. VAT, and the VAT element carries the Slovak rate as a percentage, 23 % standard. Names and parameters are in Slovak, CATEGORYTEXT comes from the Slovak tree, and HEUREKA_CPC stops at 50 €. Feedflock's Heureka.sk template is set up for all of it.

Slovak carriers, Slovak codes

DELIVERY_ID is a closed list, and the Slovak one is not the Czech list translated
Codes like SLOVENSKA_POSTA, PACKETA, PACKETA_DOMOV, SPS or WEDO_POINT exist only in Slovakia
Personal pickup has no DELIVERY code; it can only be noted in PRODUCT
DELIVERY_PRICE_COD is the total with the dobierka fee, left out when COD is not offered

Technical details

Heureka.sk accepts only carrier codes from its own list of 47, and that list barely overlaps with the Czech one: SLOVENSKA_POSTA, PACKETA_DOMOV, EXPRES_KURIER, SPS or the WE|DO codes exist only here, while ZASILKOVNA or CESKA_POSTA exist only in Czechia. An unknown code is ignored without a message, so a shipping setup copied from the Czech feed silently goes missing.

Prices follow the Czech rules: DELIVERY_PRICE is the prepaid price incl. VAT, DELIVERY_PRICE_COD the total including the cash-on-delivery fee. Personal pickup has no code at all; it belongs in PRODUCT as a note. Feedflock maps your Shopify shipping settings onto the Slovak codes.

A Slovak tree, not a translation

Heureka.sk runs its own category tree, published in Slovak
CATEGORYTEXT carries the full path with the Heureka.sk root
A mapping made for Heureka.cz does not carry over; it is a second mapping
Feedflock syncs the Slovak tree weekly and lists unmapped products

Technical details

Heureka keeps two category trees, one per country, and the Slovak one is its own tree rather than the Czech one in translation. CATEGORYTEXT needs the full path from it, starting with the Heureka.sk root, and the deepest node that fits.

Feedflock keeps the Slovak tree in the app, re-synced weekly, so you map your product types against Slovak paths directly. The Czech mapping stays with the Czech feed; the Slovak one is a separate pass, and the coverage check shows what is still unmapped.

The takeaway

Same elements, different market: euro prices, Slovak paths, Slovak carriers. Feedflock keeps the Heureka.sk feed right on its own template, from the same Shopify catalog as your Czech one.

FAQ

No. Heureka.sk needs euro prices, Slovak category paths with the Heureka.sk root, Slovak carrier codes and its own feed URL, and a Czech feed would be silently ignored where it does not fit. In Feedflock you add a second feed from the Heureka.sk template on the same Shopify catalog.

You need Slovak content in the feed: names, parameters and categories. With Shopify Markets and Slovak translations in Shopify, Feedflock takes the Slovak prices and texts from the Slovak market, even if your storefront runs in Czech or English.

HEUREKA_CPC accepts a maximum bid of 50 € per click on Heureka.sk, compared with 1,000 Kč on Heureka.cz. Leave the element out rather than sending 0, which the spec forbids. Feedflock reports any bid above the ceiling instead of cutting it.

Only codes from Heureka.sk's list of 47, for example SLOVENSKA_POSTA, PACKETA, PACKETA_DOMOV, DPD, GLS, SPS, EXPRES_KURIER or the WE|DO codes. Home delivery and pickup points are separate codes. Feedflock offers exactly that list when you map your Shopify shipping methods.

Yes. Filters by collection, tag, price or stock apply per feed, so your Slovak listing can be a subset of the Czech one, for example only products you ship to Slovakia. Sold-out variants are excluded by default.

No. The Heureka.sk template renders the full SHOPITEM structure for you. For anything custom, the Liquid editor builds your own feed in XML, CSV or JSON with a live preview.
