# How to set up Ceneo Zaufane Opinie (Trusted Reviews)

Learn how to set up Ceneo Zaufane Opinie (Trusted Reviews) transaction tracking for your Shopify store using a Custom Pixel. After each completed order, Ceneo will automatically email your customer a review questionnaire.

**Before you start, you'll need your account GUID.** You'll find it in the Ceneo merchant panel ([shops.ceneo.pl](https://shops.ceneo.pl)) under **Bezpieczeństwo zakupów → Program Zaufanych Opinii → Konfiguracja**. It looks like this: `d991a4cf-4dba-4d9a-b0fa-e9d02e20e4ef`.

## Tutorial: How to create the Custom Pixel

1.  In your Shopify admin, go to **Settings → Customer events**.

2.  Click **Add custom pixel**.
    
3.  Give the pixel a distinctive name — for example **Ceneo** — and confirm with **Add pixel**.

4.  Paste the code below into the code window and replace `__ACCOUNT_GUID__` with your own GUID from the Ceneo panel.
    
    ```javascript
    // Load the Ceneo tracking script (v5)
    window._ceneo = window._ceneo || function () {
      window._ceneo.e = window._ceneo.e || [];
      window._ceneo.e.push(arguments);
    };
    window._ceneo.e = window._ceneo.e || [];
    
    var ceneoScript = document.createElement('script');
    ceneoScript.defer = true;
    ceneoScript.src =
      'https://ssl.ceneo.pl/ct/v5/script.js?accountGuid=__ACCOUNT_GUID__&t=' +
      Date.now();
    var firstScript = document.getElementsByTagName('script')[0];
    firstScript.parentNode.insertBefore(ceneoScript, firstScript);
    
    const mapItem = (lineItem) => {
      const variant = lineItem.variant;
      return {
        // Must match the product ID in your Ceneo product feed.
        // If your feed uses SKUs, change this to: variant.sku
        id: variant.id.toString().split('/').pop(),
        price: Number(variant.price.amount),
        quantity: lineItem.quantity,
        currency: variant.price.currencyCode
      };
    };
    
    analytics.subscribe('checkout_completed', (event) => {
      const checkout = event.data.checkout;
    
      _ceneo('transaction', {
        client_email: checkout.email,
        // order_id: digits/letters only, max 32 characters
        order_id: checkout.order.id.toString().split('/').pop(),
        shop_products: checkout.lineItems.map(mapItem),
        work_days_to_send_questionnaire: 3,
        amount: Number(checkout.totalPrice.amount)
      });
    });
    
    ```
    
5.  Click **Save**, then **Connect** to activate the pixel.
    
    Optionally, adjust the **Permission** and **Data sale** settings in the _Customer privacy_ section of the pixel to match your store's consent setup.

**Tip:** the `id` of each product should match the offer ID in the product feed you send to Ceneo. If your Feedyio feed uses variant IDs, keep the code as is; if it uses SKUs, swap in `variant.sku`.

## How to verify it works

1.  Place a test order in your store.
    
2.  On the thank-you page, open your browser's developer tools (**Network** tab) and look for requests to `ssl.ceneo.pl` — you should see `ct/v5/script.js` load and a transaction request fire.
    
3.  The transaction should appear in the Ceneo merchant panel under the Zaufane Opinie program shortly after.
    
4.  The questionnaire email is sent after the number of business days set in `work_days_to_send_questionnaire`.
    

## Good to know

-   Because the script passes the customer's email to Ceneo, make sure your store's terms include the recommended clause about sharing email and purchase data with Ceneo for the review questionnaire (wording is provided in the Ceneo merchant panel).
    
-   Ceneo Zaufane Opinie has no server-side API — this Custom Pixel is the supported integration path on Shopify.
    
-   If you only want to track customers who explicitly consented, Ceneo's script supports manual consent mode — see the [official Ceneo integration guide](https://github.com/ceneo/ceneo-integration).
