Google Consent Mode with Piwik PRO Consent & Tag Manager

I think any TMS should be capable of setting Consent defaults, even Piwik’s.

It’s not about ability, it’s just recommended. See my answer here:

Google Consent Mode: analytics_storage denied

That was one of the reasons why we didn’t include the defaults in the code. We didn’t want to skip the defaults part in case there is a failure with the Piwik PRO container (e.g. outage, blocking) We wanted them (the defaults) to be on top of any potential tool that could either make use of them or modify them. As you’ve mentioned - it’s of course possible to add those in the integration tag but we can’t really advise on doing so because of the mostly asynchronous manner of Piwik PRO Tag Man…

@loldenburg

And maybe I misunderstand how Piwik’s Consent Manager works, but Google consent mode v2 integration | Piwik PRO help center mentions we should update the Consent Manager defaults when the Event is stg.consentDecisionMade.

But doesn’t that apply only to the rare cases when somebody first gives their consent (or even rarer, when they update consent)?

=> If we only use that stg.consentDecisionMade Event, there will be no Consent given for any Pageviews where there was no interaction with the Consent Manager (=99% of Pageviews)…

And also the page view event
