I am currently using the Stape Server GTM app for server-side tracking for a website. Now the client is using the app on their website for Consent Management
My main question is:
If using this kind of custom consent banner app,
How does Google Analytics 4 (or other tags) get the consent signal?
How do I send and adjust this consent signal in the Google Tag Manager setup?
Any banner, custom or not should ultimately utilize Google’s Consent Mode v2 (which would also be then passed to the server), so if your custom banner does not do that already you can do consent pushes with Tag Manager Template Gallery based on either cookies or DL (or any other means with which your consent banner exposes the decisions made by the customer)
