Integrate HandL UTM Grabber with Cookie Notice

UTM attribution overview

Set up Cookie Notice with HandL UTM Grabber so UTM parameters are only captured after the visitor gives cookie consent. This keeps attribution compliant with GDPR and CCPA.

Setup

1. Install Cookie Notice and HandL UTM Grabber V3
2. Enable GDPR mode for Cookie Notice in HandL UTM Grabber > GDPR
3. UTM Grabber checks the cookie_notice_accepted cookie before capturing UTMs
4. Until the visitor clicks Accept, no UTM cookies are set
5. Test in incognito window after clearing cookies

Note: UTM capture is blocked until the visitor accepts cookies via the Cookie Notice banner.

How it works

HandL UTM Grabber hooks into the is_ok_to_capture_utms filter. Until consent is granted, no UTM cookies are written. After consent, everything works as usual: shortcodes, hidden fields, and webhook data all pull from stored cookies.

Enable GDPR mode in UTM Grabber

Go to HandL UTM Grabber > GDPR and enable the Cookie Notice integration toggle. See GDPR Implementation Guide.

Troubleshooting

• UTMs not capturing? Confirm marketing/statistics consent was accepted, not just functional cookies
• Clear cookies and test in an incognito window after changing consent settings
• Ensure UTM Grabber is listed/enabled in the consent plugin's integration or script blocker settings
