Hello Kuba,

We are using One Trust as our cookie CMP. We are still not ready to commit to use PPTM as our TMS, specially because of its lack of a feature where I can refer to other variables in HTML Tags and Custom Javascript Variables. This makes the switching setup harder.

Also regarding tracking, I am using HTML Tags instead of your GTM Template.  
How could I use the tracking API? Thanks
