trackConsentAllow({
    consentScopes: ["necessary", "marketing", "personalization"],
    basisForProcessing: "consent",
    consentUrl: "https://www.example.com/",

trackConsentPending

Some consent management platform installations, allow the user to take website actions or/and navigating to other pages without accepting the consent prompt. To track the unconfirmed selection of user consent, you can use the trackConsentPending method with the following attributes:

    consentVersion: "1.0",
    domainsApplied: ["https://www.example.com/"],
    gdprApplies: true
});

trackConsentImplicit

Some consent management platforms have a configuration which allows the setting of consent implicitly after a set of user interactions like clicks, scroll etc. To track the implicit selection of a user consent, you can use the trackConsentImplicit method with the following attributes:

import { trackConsentImplicit } from "@snowplow/browser-plugin-enhanced-consent";

trackConsentImplicit({
    consentScopes: ["necessary", "marketing", "personalization"],
    basisForProcessing: "consent",

trackCmpVisible

Consent management platform banners are an important part of a website’s first impression and performance. Snowplow provides a way to track what we call elapsedTime, which is the timestamp of the consent management platform banner becoming visible on the user’s screen.

import { trackCmpVisible } from "@snowplow/browser-plugin-enhanced-consent";

trackCmpVisible({
    /* Using the performance.now API to retrieve the elapsed time from the page navigation. */
    elapsedTime: performance.now(),
});
