Google Consent Mode Listener tag

The Google Consent Mode Listener tag monitors consent status changes and pushes a dedicated event to the dataLayer whenever a monitored consent type is updated. This allows Google Tag Manager to react to consent changes and trigger tags, scripts, or workflows based on a user's latest consent preferences.

How to access the Google Consent Mode Listener tag

The tag is a completely free solution available for all users. To start configuring the tag, download the template from the Stape GitHub repository.

Import the template into your web GTM container via Templates → Tag Templates → Import.

How it works

The Google Consent Mode Listener tag continuously monitors Consent Mode states configured in GTM. When one or more monitored consent types change, the tag pushes a dedicated event to the dataLayer.

By default, the event name is: stape_consent_update

The event also includes the current consent state for all monitored consent types, making it easy to use the updated values in GTM triggers and tags.

Benefits of Google Consent Mode Listener tag

• More reliable consent-based tracking. Detect consent changes immediately and trigger tags only after updated consent becomes available.
• Better control over non-Google tags. Create a dedicated trigger for consent updates and ensure third-party tags react correctly to user consent decisions.
• Improved troubleshooting. With a visible consent update event in GTM Preview mode, you can verify consent changes more easily, which contributes to faster debugging and validation.
• Consistent consent handling. Ensure tracking logic always uses the latest consent state and prevent tags from firing based on outdated consent values.

Start tracking consent updates automatically

Use the Google Consent Mode Listener tag to create a dedicated consent update event in GTM and simplify consent-based tracking workflows.
