    Note

    CookieYes will notify Shopify when consent is given or revoked. Shopify will collect marketing and analytics data only if consent is obtained in the specified regions.

    Step 5: Verify Integration

    To verify GCM integration on your website,

    1. Navigate to Advanced Settings in the CookieYes Dashboard.
    2. Click the Check Now button against the Check GCM status. If the configuration is correct, you will see a success message stating, ‘No error detected’. If you encounter any errors after running this check, refer to our GCM Troubleshooting Guide to resolve them and check again.

    Note

    The Check GCM status verification does not work for password-protected Shopify websites.

    To further confirm the setup is correct, follow the steps in our Verification Documentation.

    Should you encounter any issues, our dedicated GCM support team are here to assist you.

    Setting Advanced Consent Mode in GCM

    To set Advance Consent Mode, follow the below set:

    1. Navigate to CookieYes Dashboard > Advanced Settings.
    2. To set up Advanced Consent Mode in GCM, toggle the button (to the right) labelled “Allow Google tags to fire before consent”.

    3. Now, go back to your GTM account, click Submit, and then Publish to reflect the change on your website.

    Enabling only the Support GCM option implements basic functionality, firing only allowed tags based on user consent. When you also activate Allow Google tags to fire before consent, it ensures Google tags fire even before the user consents to the banner, but they operate without setting cookies until the user provides consent. This balance allows for some data collection while respecting user privacy choices.
