How to use __tcfapi to define consent mode v2 in gtm?

[tiago-snigel]

I'm trying to implement user consent management in my website using Google Tag Manager (GTM) and the Transparency and Consent Framework (TCF) API v2.

I'm unsure about the proper way to utilize the __tcfapi function within GTM to update Consent Mode v2 based on the TCF data received from my CMP. I've looked at some documentation and examples, but I'm still struggling to understand how to correctly map the consent information and update GTM's consent mode accordingly.

Any guidance or code examples on how to achieve this using GTM and the TCF API v2 would be greatly appreciated.

My plan of action would be to create a custom html tag and have the addEventListener to get the tcdata and with that tcdata set the consent.

gtag('consent', 'update', {
  'ad_storage': 'granted',
  'ad_user_data': 'granted'
...
});

Is this something that should work? And how about the trigger should I use a custom event?

Thank you very much in advance.
