# Active Cookie Consent Client-Side Implementation
For Experience API implementation, see the API cookie consent guide
**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. Learn more about active consent in The Dynamic Yield Privacy Center.
***
## Set the user's consent status
Use `DY.userActiveConsent` to declare, update, and verify a user's consent status.
```javascript
DY.userActiveConsent = { accepted: };
```
* `true` – User has granted consent
* `false` – User has not granted consent, had denied consent, or consent status is unknown
Set the value to reflect the user's current consent status. If no valid consent signal exists, use `false`.
You can set this property before the dynamic Yield script loads, and update it later whenever the user consent status changes.
***
## Common implementation scenarios
* **Consent available at page load: **If your site already knows the user's consent status when the page loads, set the API to declare the status before the page loads.
* **Consent granted or withdrawn during the session:** A user can grant or deny consent at any juncture you provide on your site, such as a cookie management panel or consent popup.
* **Consent verification:** At any time, you can check the value of `DY.userActiveConsent.accepted` to determine a user's consent status.
***
## Verification and enablement
1. Implement the API on your site. It is 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.
