Our.Umbraco.CookieConsent

Easily add a configurable cookie consent banner to your Umbraco site. Features include a dashboard for customizing behavior, appearance, and translations, using the Orestbida/CookieConsent library.

Requirements

Umbraco 13 on .NET 8: 13.x.x releases
Umbraco 17 on .NET 10: 17.x.x releases

Installation

dotnet add package Our.Umbraco.CookieConsent

Then render the banner by adding this line to your main layout file (_Layout.cshtml or equivalent):

@await Component.InvokeAsync("Cookie")

The settings table is created on the first startup, and the dashboard shows the default settings until you save for the first time

Configuration

1. Access the dashboard
   Navigate to the Settings tab in the Umbraco Backoffice, and then select the Cookie Consent dashboard to manage all settings related to your banner.

2. Customize appearance and behavior
   Use the dashboard to configure:

   • Position of the banner on your site.
   • Categories of cookies to display.
   • Layout and styles to match your site’s design.
   • ...

3. Manage translations

   • Translations for the popup text can be managed in the Translations section of Umbraco, under the key Our.Umbraco.CookieConsent.
   • The available languages for the cookie consent popup depend on the languages configured for your Umbraco site.
   • Keys for a category are created the first time you save the settings with that category enabled.

Custom scripts

You can define custom scripts that are injected only after user consent, based on the selected cookie category (e.g. Analytics, Marketing, etc.).

To do so:

• Navigate to the "Custom scripts" section in the dashboard
• Add a new entry with the target category (Analytics, Marketing, etc.)
• Paste your script using safe JS, such as dynamic script injection

Important: HTML <script> tags cannot be directly used inside JavaScript blocks. Instead, use JavaScript to create and inject scripts dynamically.

Example: Google Analytics script

    var gtagScript = document.createElement('script');
    gtagScript.src = 'https://www.googletagmanager.com/gtag/js?id=G-CN4GDXXXXX';
    gtagScript.async = true;
    document.head.appendChild(gtagScript);

    gtagScript.onload = function () {
        window.dataLayer = window.dataLayer || [];
        function gtag(){ dataLayer.push(arguments); }
        window.gtag = gtag;

        gtag('js', new Date());
        gtag('config', 'G-XXXX');
    };

This logic will only be executed if the user accepts the analytics category

Built-in scripts

The "Built-in Scripts" section covers integrations that need to run before consent is given, which custom scripts cannot do

Add an entry, pick a provider and fill in its ID. Each one loads before consent is given and is held until the visitor makes a choice.

The two Google providers implement Google Consent Mode: the package sets every consent signal (ad_storage, ad_user_data, ad_personalization, analytics_storage, ...) to denied before any Google script runs, then updates them as soon as the visitor makes a choice, so Google receives consent signals rather than nothing at all. Pick the one that matches how Google is loaded on your site:

• Google Analytics loads gtag.js directly. Fill in your measurement ID (G-XXXXXXXXXX). Use this when you do not go through Tag Manager, and in that case do not also load GA4 from a container or it runs twice.
• Google Tag Manager loads the gtm.js container. Fill in your container ID (GTM-XXXXXXX). The package only sends the consent signals; for them to gate anything, turn on the Consent settings of your tags inside Tag Manager.
• Facebook Pixel loads the Meta Pixel with consent revoked (fbq('consent', 'revoke')), then grants it once the visitor accepts the Marketing category and revokes it again on withdrawal. Fill in your pixel ID (a numeric value). Keep the Marketing category enabled, or the Pixel stays revoked.

Leave the ID empty and nothing is injected.
