# GA4 Shopify Pixel

Connect your GA4 account to your Shopify Checkout Extension to collect Zigpoll survey data in your GA4 analytics dashboard.

{% hint style="info" %}
This guide is specific to the Shopify Checkout Extension. For the general Google Analytics integration, see [Google Analytics](/integrations/google-analytics.md).
{% endhint %}

#### Step #1: Create a Custom Pixel in Shopify

1. Go to your **Shopify Dashboard → Settings → Customer Events**.
2. Click **Add custom pixel**.
3. Paste the following JavaScript code into the code block.

{% hint style="warning" %}
Replace **G-XXXX** with your GA4 Measurement ID. You can find your GA4 ID in GA4 by going to: Property settings → Data collection and modification → Data Streams → Click applicable stream → copy "Measurement ID".
{% endhint %}

```javascript
/* Zigpoll GA Integration Pixel */
var f = document.getElementsByTagName('script')[0];
var j = document.createElement('script');
j.async = true;
j.src='https://www.googletagmanager.com/gtag/js?id=G-XXXX';
f.parentNode.insertBefore(j, f);

window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());
gtag('config', 'G-XXXX');

analytics.subscribe("zigpoll-event", (event) => {
  const { customData } = event;

  gtag("event", customData.action, {
    event_category: customData.category,
    event_label: customData.label,
    order_id: customData.order_id,
    zigpoll_response: customData.response,
    zigpoll_question: customData.question
  });
});
```

{% hint style="info" %}
Shopify only allows web pixels on the **Thank You** page as of now. We hope they will allow web pixels on the Order Status page in the future and will update this page accordingly.
{% endhint %}

#### Step #2: Set Up Custom Dimensions in GA4

1. Go to your **GA4 Dashboard**.
2. Click **Admin → Custom Definitions**.
3. Click **Add custom dimension** and enter the following:

| Dimension Name   | Event Parameter    |
| ---------------- | ------------------ |
| Zigpoll Response | `zigpoll_response` |
| Zigpoll Question | `zigpoll_question` |

Once both dimensions are created, Zigpoll survey response data will begin appearing in your GA4 reports.
