Problem
script.js and u.js only load on page refresh after consent. First session (with UTMs + referrer) is lost.
Required Behavior
On consent accept → immediately inject both scripts without a page reload.
Implementation by CMP
OneTrust
javascript
function OptanonWrapper() { if (OnetrustActiveGroups.includes('C0002')) { // Performance/analytics category injectKickbite(); } }Cookiebot
javascript
window.addEventListener('CookiebotOnAccept', function () { if (Cookiebot.consent.statistics) { injectKickbite(); } });Usercentrics
javascript
window.addEventListener('UC_UI_CMP_EVENT', function (e) { if (e.detail && e.detail.type === 'ACCEPT_ALL') { injectKickbite(); } });Google Tag Manager (Consent Mode)
In GTM, create a Custom Event trigger on consent_update, then fire a tag that calls injectKickbite().
Shared Injection Function
javascript
function injectKickbite() { if (window.__kickbiteLoaded) return; // prevent double-load window.__kickbiteLoaded = true; var scripts = [ 'https://your-domain.com/script.js', 'https://your-domain.com/u.js' ]; scripts.forEach(function (src) { var s = document.createElement('script'); s.src = src; s.async = true; document.head.appendChild(s); }); }Why This Works
At the moment of accept, window.location.href still contains the original UTM parameters and document.referrer still holds the traffic source. No data is lost.
Checklist
Confirm which CMP is used across BE, FR, NL, DE, AT, CH
Implement the consent-change callback for that CMP
Add the
injectKickbite()function with double-load guardVerify in browser DevTools: scripts fire immediately on accept (no reload)
Confirm UTM params are captured in the first Kickbite request
