Fingerprinting

Accepting analytics or tracking cookies will create a unique UUID to allow you to differentiate events from different users when using server-side cookies in a system such as CAPI.

To enable fingerprinting you must have a configuration like this or use the default one (which is already GDPR compliant):

<CookieBox fingerprinting={true} />
<!-- OR -->
<CookieBox
   fingerprinting={{
      uuid: 'a-unique-user-identifier',
      cookie: {
         name: 'fingerprint',
         path: '/',
         secure: true,
         sameSite: 'strict',
      },
   }}
/>
