Active Cookie Consent Client-Side Implementation

Active cookie consent enables your website to tell Dynamic Yield whether a user has consented to cookies, so Dynamic Yield can apply the correct data collection and personalization behavior.

This guide explains the client-side implementation for sites that use the Dynamic Yield script, including consent handling at page load and during runtime. Learn more about active consent in The Dynamic Yield Privacy Center.

Page-load declaration

Set the user's consent status before the Dynamic Yield script loads. The declaration must be included on every page:

DY.userActiveConsent = { accepted: <true | false> };

• true – User has granted consent
• false – User has not granted consent or consent status is unknown

This parameter is set to false unless true is actively received. Pass true only if you already have a valid consent signal for the user, such as consent stored by your consent management platform, your own cookie or storage mechanism, or another consent source used by your site.

Runtime update

Update the user’s consent status after the script loads:

DYO.ActiveConsent.updateConsentAcceptedStatus(<true | false>);

• true – User has granted consent
• false – User has denied consent

Verification and enablement

1. Implement the APIs on your site. They are ignored until active cookie consent is enabled.
2. In Experience OS › Settings › Data Privacy › Active Cookie Consent, click Preview to experience the site as if active cookie consent is enabled.
3. After successful verification, contact Dynamic Yield Support to enable active cookie consent.
4. At any time, check current consent status using:

DYO.ActiveConsent.isUserOptOut() ? 'Consent not granted' : 'Consent granted';
