google_tag_manager_consent_mode_banner

This module provides a lightweight (1.9 kB) cookie consent banner built specifically to integrate with Google Tag Manager's Consent Mode v2. It gives PrestaShop store owners a straightforward way to meet GDPR, CCPA, and other privacy regulations by letting visitors choose their cookie preferences, while automatically pushing consent state into the GTM DataLayer following the Consent Mode API specification.

• GTM Consent Mode v2 compatible: Consent signals are pushed to the GTM DataLayer automatically, enabling tag-level consent controls in Google Tag Manager without additional configuration.
• Granular user preference control: Visitors can specify consent for distinct cookie categories, such as necessary, analytics, and marketing cookies.
• Customizable banner appearance: The banner can be displayed as a bar or a modal, and appearance, messaging, and consent types are all configurable from the module settings screen.
• Optional GTM snippet embedding: The module can optionally inject GTM tracking snippets directly, or defer to existing theme code or other modules for snippet placement.
• Custom CSS support: An additional settings screen allows custom CSS to tailor the banner's visual style to match the store's branding.

This module is best suited for store owners who already use Google Tag Manager and need to align their tag firing with visitor consent choices. It is particularly valuable for stores targeting EU or California-based customers where GDPR and CCPA compliance is required. After deploying the banner, GTM tag consent checks should be reviewed using the Consent Overview screen in GTM to ensure all tags honour the consent signals correctly.
