If you use Google Analytics to collect data on your Shopify store’s visitors you need to display a consent popup to ask to use their data. To achieve this, set up Google consent mode v2 advanced in Shopify.
In this article, we’ll show you how to do it.
Before you start
Here are a few things to know before you start:
Google consent mode v2 processes the consent preferences of your users obtained through your consent popup. It adjusts the functioning of analytics, ads, and third-party tags responsible for creating or accessing cookies based on these preferences.
There are two different modes available in this version: basic and advanced. You can implement both in Cookie Information. The basic consent mode doesn’t allow you to collect user data or even consent status until the user agrees. In the advanced consent mode, Google tags are loaded before the consent popup displays to users. Google collects cookieless data without personal identifiers.
To learn how to customize your cookie consent template, see the style guide.

window.addEventListener("CookieInformationConsentGiven", () => {
let consentSignals = {};
let consentCookieReady = false;
let customerPrivacyAPIReady = false;
const checkAndSetTrackingConsent = () => {
if (consentCookieReady && customerPrivacyAPIReady && Object.keys(consentSignals).length > 0) {
window.Shopify.customerPrivacy.setTrackingConsent(
{
"analytics": consentSignals['cookie_cat_statistic'] || false,

if (consentCookie) {
const consent = JSON.parse(consentCookie);
if (consent) {
consentSignals = consent.consents_approved || [];
consentSignals = consentSignals.reduce((acc, curr) => {
acc[curr] = true;
return acc;
}, {});
consentCookieReady = true;
checkAndSetTrackingConsent();
}
}
}
const customerPrivacyAPIInterval = setInterval(() => {
if (window.Shopify.customerPrivacy) {
clearInterval(customerPrivacyAPIInterval);
customerPrivacyAPIReady = true;
checkAndSetTrackingConsent();
}
}, 100);
});
};
window.Shopify.loadFeatures(
[
{
name: 'consent-tracking-api',

},
],
error => {

}
setupListenerForConsentGathering();
addCookieInformationConsentScript();
