### Minified script for Shopify theme.liquid to track Gorgias events

Source: https://help.littledata.io/partner-recipes/gorgias/tracking-gorgias-google-analytics

Paste this script into the Shopify theme.liquid file. It waits for the Gorgias widget to load, then listens to chat events and sends them to Google Analytics via gtag. If gtag has not loaded yet, events are queued until Google Analytics is ready.

```html
<script>
	var eventsToTrack = [
		{ gorgias: "message:sent", ga: "gorgias_message_sent" },
		{ gorgias: "message:received", ga: "gorgias_message_received" },
		{ gorgias: "widget:opened", ga: "gorgias_widget_opened" },

### Raw script for adapting Gorgias event tracking

Source: https://help.littledata.io/partner-recipes/gorgias/tracking-gorgias-google-analytics

Full script without HTML wrapper, provided for adaptation to track different events or send to different data destinations. It maps Gorgias events to Google Analytics event names and uses gtag to send them.

```javascript
var eventsToTrack = [
	{
		gorgias: "message:sent",
		ga: "gorgias_message_sent",
	},
	{
		gorgias: "message:received",
		ga: "gorgias_message_received",
	},
	{
		gorgias: "widget:opened",
		ga: "gorgias_widget_opened",
	},
	{
		gorgias: "widget:closed",
		ga: "gorgias_widget_closed",
	},
];

var initGorgiasChatPromise = window.GorgiasChat
	? window.GorgiasChat.init()
	: new Promise(function (resolve) {
			window.addEventListener("gorgias-widget-loaded", function () {
				resolve();
			});
		});

initGorgiasChatPromise.then(function () {
	eventsToTrack.forEach(function (event) {
		GorgiasChat.on(event.gorgias, function (data) {
			gtag && gtag("event", event.ga);
		});
	});
});
```

### Rebuy Smart Cart tracking script for Google Analytics

Source: https://help.littledata.io/partner-recipes/rebuy/tracking-rebuy-smartcart

Paste this script into the Shopify theme.liquid file or assets loaded from the theme. It listens for Rebuy Smart Cart events and sends them to Google Analytics via the gtag library. If gtag is not yet loaded, events are queued until GA is ready.

```html
<script>
	const eventsToTrack = [
		{ rebuy: "rebuy:smartcart.show", ga: "rebuy_smartcart_shown" },
		{ rebuy: "rebuy:smartcart.hide", ga: "rebuy_smartcart_hidden" },
		{
			rebuy: "rebuy:smartcart.line-item-increase",
			ga: "rebuy_smartcart_item_increase",
		},
		{
			rebuy: "rebuy:smartcart.line-item-decrease",
			ga: "rebuy_smartcart_item_decrease",
		},
		{
			rebuy: "rebuy:smartcart.line-item-removed",
			ga: "rebuy_smartcart_item_removed",
		},
		{
			rebuy: "rebuy:smartcart.item-switch-to-subscription",
			ga: "rebuy_smartcart_switched_to_subscription",
		},
		{
			rebuy: "rebuy:smartcart.item-switch-to-one-time",
			ga: "rebuy_smartcart_switched_to_onetime",
		},
	];
	eventsToTrack.forEach(function (event) {
		document.addEventListener(event.rebuy, function (props) {
			let params = {};
			const item = props?.detail?.item;

			if (item) {
				const { sku, product_id, variant_id, product_title } = item;
				params = {
					...params,
					sku,
					product_id,
					variant_id,
					product_title,
				};
			}
			gtag && gtag("event", event.ga, params);
		});
	});
</script>
```

Source: https://help.littledata.io/advanced/developer/gtm-and-google-analytics-data-layer-for-shopify

### Block client-side events based on consent with AnalyticsJS middleware

Source: https://help.littledata.io/integrations/shopify-to-segment/segment-consent-management

Use this middleware script to drop events from being triggered if `context.consent.categoryPreferences.Advertising` is not `true`. It temporarily implements `addSourceMiddleware` before the real script loads.

```javascript
window.analytics = window.analytics || [];
// Temporary implementation before the real script loads
if (!window.analytics.addSourceMiddleware) {
  window.analytics.addSourceMiddleware = function () {
   const e = Array.prototype.slice.call(arguments);
   e.unshift('addSourceMiddleware');
   window.analytics.push(e);
   return window.analytics;
  };
}
window.analytics.addSourceMiddleware(({ payload, next }) => {
    if(payload?.obj?.context?.consent?.categoryPreferences?.Advertising) {
        next(payload);
    }
});
```

### Track a custom event with parameters using gtag

Source: https://help.littledata.io/advanced/developer/gtm-and-google-analytics-data-layer-for-shopify

Use this snippet to track a custom event with additional parameters, such as promo details, in Google Analytics. The parameters are passed as an object to gtag.

```javascript
gtag('track', 'promo_click', {

  'promo_location': 'HOMEPAGE'
})
```

### Check cart attributes for client ID in browser console

Source: https://help.littledata.io/advanced/troubleshooting/troubleshooting-marketing-attribution-for-shopify

Use this snippet in the browser console to request the current Shopify cart and verify that the `attributes` field contains `google-clientID` or `segment-clientID`. If the attribute is missing, it logs 'Client ID attribute missing'.

```javascript
var request = new XMLHttpRequest();
request.open("GET", "/cart.js", true);
request.onload = () => {
	var data = JSON.parse(request.responseText);
	data.attributes["google-clientID"] || data.attributes["segment-clientID"]
		? console.log(data.attributes)
		: console.log("Client ID attribute missing");
};
request.send();
```

### Track a custom event with gtag

Source: https://help.littledata.io/advanced/developer/gtm-and-google-analytics-data-layer-for-shopify

Use this snippet to track a custom event, such as a navigation button click, in Google Analytics. Littledata's app embed loads gtag.js on all pages, and the event queue handles calls before the library loads.

```javascript
gtag('track', 'nav_button_click')
```
