CookieFirst

To learn more about the integration, read more in the Cookiefirst API documentation.

Event listener

The following code works asynchronously with CookieFirst Banner API and listens for the cf_init and cf_consent, parses the consent state and eventually calls the walker consent command:

(function () {
  function handleConsent(consent) {
    if (!consent) return; // Process only explicit consent

    // Renaming of the categories
    const mapping = {
      necessary: 'functional',
      functional: 'functional',
      performance: 'analytics',
      advertising: 'marketing',
    };

    const state = {};
    Object.keys(consent).forEach(function (category) {
      state[mapping[category] || category] = consent[category];
    });

    elb('walker consent', state);
  }

  if (window.CookieFirst) {
    // Already loaded
    handleConsent(CookieFirst.consent);
  } else {
    // On load
    window.addEventListener('cf_init', function () {
      handleConsent(CookieFirst.consent);
    });
  }

  // On change
  window.addEventListener('cf_consent', function (e) {
    handleConsent(e.detail);
  });
})();

Ensure the elb function is available.
