How it works

From feed to the first box in four steps

Details: how it works

Step 1: Send the feed

All you need is a product XML feed in the Heureka/Zbozi format, which you most likely already have. Optionally add an availability and a transaction feed — they keep stock and prices up to date.

https://your-store.com/feed/heureka.xml
https://your-store.com/feed/availability.xml

Step 2: Add the script

You choose the integration to fit your store: a JavaScript snippet in the template, Google Tag Manager, the REST API, or a point‑and‑click wizard that needs no IT work. It usually takes a few minutes.

For developers

<div id="customize_box_detail"></div>
<script>
  var _cmq = _cmq || [];
  _cmq.push(['action', 'show']);
  _cmq.push(['box', 'BOX_ID']);
  _cmq.push(['web', 'YOUR_WEB']);
  _cmq.push(['elementid', 'customize_box_detail']);
  _cmq.push(['userid', '']);
  _cmq.push(['itemid', 'PRODUCT_ID']);
  _cmq.push(['exceptid', '']);
  _cmq.push(['process']);
</script>
<!-- + loader script //customize.cz/add/tracker.js -->

Step 3: We pick the products

Customize.cz evaluates the visitor's behaviour in real time and picks products using the chosen logic: related, alternative, recently viewed, best‑selling or personal selection.

Step 4: The box renders

The box renders in your template. Clicks and purchases are written to statistics, which the commission is calculated from — you see exactly what each box brought in.

<script>
  var _cmq = _cmq || [];
  _cmq.push(['action', 'conversion']);
  _cmq.push(['web', 'YOUR_WEB']);
  _cmq.push(['transaction', 'ORDER_NUMBER']);
  _cmq.push(['itemid', 'PRODUCT_ID']);
  _cmq.push(['price', 'UNIT_PRICE_WITH_VAT']);
  _cmq.push(['quantity', 'QUANTITY']);
  _cmq.push(['process']);
</script>

Why stop pairing products by hand

Manual pairing

Related and alternative products are paired by hand; the work grows with the number of products.
Paired products go stale: sold‑out items stay, new items are missing.
Every customer sees the same offer.
Needs a full‑time person or an agency.

Customize.cz

Products are picked automatically from the feed by category, parameters, price and customer behaviour.
The feed is imported regularly; the availability feed keeps stock and prices up to date.
The selection differs by what the customer viewed, bought and has in the basket.
We set up the boxes; you manage them in the administration.

What it costsFirst month free

Commission on orders.
No flat fee.

You pay no flat fee, no charge per impression or click. You pay a commission on converted orders – orders that contain at least one product bought through our box. The commission is calculated a month in arrears from orders already paid.
