HTML Box Pro: Add Idealo Conversion Tracking on Order Confirmation (German Price Comparison)

Option A - Image pixel (recommended starter)

Use product total without tax ( {order_total_products_tax_excluded} ) when Idealo asks for basket value excluding VAT / shipping. If your Partner brief asks for another amount, swap to {order_total_paid_tax_excl} or {order_total_paid} as documented in your Idealo integration sheet.

<img
  src="https://marketing.net.idealo-partner.com/ts/YOUR_PARTNER_CODE/tsa?typ=i&trc=default&ctg=Sale&sid=checkout&cid={order_id}&orv={order_total_products_tax_excluded}&orc={order_currency_iso_code}"
  width="1"
  height="1"
  alt=""
  style="display:none"
/>

Option B - JavaScript pixel (timestamp + URL encoding)

Use this when you want a dynamic tst timestamp and safer encoding. Variables are still replaced server-side by HTML Box Pro.

<script>
(function () {
  var partnerCode = 'YOUR_PARTNER_CODE';
  var orderId = '{order_id}';
  var orderValue = '{order_total_products_tax_excluded}';
  var currency = '{order_currency_iso_code}';
  var productIds = '{order_products_id}';

  if (!orderId) {
    return;
  }

  var src = 'https://marketing.net.idealo-partner.com/ts/' + partnerCode + '/tsa'
    + '?typ=i'
    + '&tst=' + Math.floor(Date.now() / 1000)
    + '&trc=default'
    + '&ctg=Sale'
    + '&sid=checkout'
    + '&cid=' + encodeURIComponent(orderId)
    + '&orv=' + encodeURIComponent(orderValue)
    + '&orc=' + encodeURIComponent(currency);

  // Optional helper for support / debugging in DevTools
  if (productIds) {
    src += '&notes=' + encodeURIComponent(productIds);
  }

  var img = new Image(1, 1);
  img.src = src;
})();
</script>

Traffic from Idealo often arrives with a click identifier in the landing URL (commonly idealoid / iclid - confirm the exact parameter with your Partner docs). Storing it in a first-party cookie and appending it as cli on confirmation improves attribution when third-party cookies are blocked.

Create a second HTML Box Pro block on a global hook (e.g. displayHeader), visible on all pages, with a small script that saves the query parameter. Then extend the confirmation pixel with &cli= plus the cookie value. Keep marketing consent / cookie rules in line with your DE privacy setup (TTDSG / GDPR).

<script>
(function () {
  var param = 'idealoid'; // or the parameter name from your Idealo brief
  var params = new URLSearchParams(window.location.search);
  if (!params.has(param)) {
    return;
  }
  var value = params.get(param);
  var maxAge = 60 * 24 * 60 * 60; // 60 days
  document.cookie = param + '=' + encodeURIComponent(value)
    + ';path=/;max-age=' + maxAge + ';SameSite=Lax';
})();
</script>
