Method to manually trigger the cookie consent banner

Deutsch Diskussion Technische Fragen & Antworten

Topic summary

Problem: Users need a way to manually re-trigger Shopify’s default cookie consent banner so visitors can review and change their cookie preferences at any time, as required by EU GDPR/DSGVO regulations.

Solution Found: A working code snippet was shared:

<a href="#" onclick="event.preventDefault(); privacyBanner.showPreferences();">Privacy Preferences</a>

This link can be embedded directly in theme files (e.g., footer.liquid) to allow users to reopen the cookie settings modal on demand.

Implementation Notes:

  • The link must be added directly in the Liquid theme code, not through Shopify’s navigation menu system
  • Multiple users confirmed this works in Dawn theme (versions mentioned include 15.0/15.1)
  • The solution is considered a temporary workaround/hack, as Shopify’s native cookie banner doesn’t include this functionality by default

Community Consensus:

  • Participants agree this feature should be a standard part of Shopify’s cookie banner, as GDPR/DSGVO legally requires users to be able to modify their cookie consent at any time
  • Several users successfully implemented the solution and confirmed it works across different themes (Dawn, Canopy)
  • There’s a call for Shopify to integrate this natively rather than requiring custom code

Hey @BenjaminHD

Thank you for bringing up your point on our new Shopify Cookie Consent Banner. However, you say “But the EU GDPR law suggests that users have to be able to review and reset their settings, so i tried to create a link to do so” - can you give me an example of exactly what you mean? The app allows you to offer the customer to choose whether they want to consent to the following types of cookies, or not, which is currently required by the ePR (e-privacy) law the that in the settings:

  • Essential cookies are allowed by default as they are necessary for the proper functioning of the Storefront and are permitted by the GDPR and ePR
  • Non-essential cookies can be allowed or not by the user
  • The same goes for persistent and session cookies, which also be allowed or not by the user.

This requirement under the current GDPR provision is that user consent is allowed to be ‘specific and informed’. Looking through the online Literature like this publication and this one, you see the emphasis is on the processing by purpose or usage and not by vendor, but at least one CMP shows usage groups below the purpose groups… Some CMPs like the GDPR App from BeeClever show the cookies included in each purpose to meet the ‘informed’ part, but I think that can also be met by your cookie policy i.e. just make sure you have all that information in the policies and you are fine.

Regarding your code - I took a :eyes: at the dev docs and concluded the following:

window.Shopify.customerPrivacy.shouldShowBanner(true) might not be the correct way to force the banner to show again. According to the Shopify dev docs, there isn’t a direct method named shouldShowBanner to control the visibility of the cookie consent banner. Shopify’s customer privacy API primarily focuses on methods related to customer data, like customerPrivacy.showBanner() or managing customer data consent. So that could be a potential issue in your code e.g. the method window.Shopify.customerPrivacy.shouldShowBanner(true) is not directly supported by Shopify’s API or documentation for handling cookie consent banner visibility.

And ensure that your script is executed after the Shopify customer privacy script is fully loaded. If your script runs before the Shopify script that defines window.Shopify.customerPrivacy, it will not work because window.Shopify.customerPrivacy would be undefined. There might also be an issue with the event listener not correctly binding to the link, especially if the link is dynamically added to the page after the DOM has loaded or if the script runs before the link is present in the DOM.

Double-check the Shopify documentation or any updates to ensure you’re using the correct method to trigger the cookie consent banner. As of my last update, directly manipulating the visibility of the cookie consent banner through a JavaScript API call like shouldShowBanner was not documented. Instead, consider using documented methods or a different approach to manage cookie consent visibility. Make sure that your custom script runs after all Shopify scripts have loaded. You might want to place your script at the bottom of the theme.liquid file or within a $(document).ready() function if you’re using jQuery, to ensure it executes after the page has fully loaded.

Shopify’s documentation focuses on adding a cookie compliance banner and ensuring it meets GDPR requirements without explicitly detailing methods to programmatically re-trigger the consent banner via JavaScript​​. For GDPR compliance, the emphasis is on obtaining explicit consent before serving cookies, providing clear information about cookie usage, and making it as _easy to withdraw consent as it is to give it_​​.

FYI: see another thread from last week on this topic here.

Hope that helps! :wink:
