You can send all the events that occur in your Quizzes/Surveys/Polls/Forms to your own Google tag manager to trigger actions accordingly.
As an example, you can fire different pixels based on Quiz responses, and use those pixels to run various re-marketing campaigns per user segment.
Follow these steps to configure the Opinion Stage / GTM integration:
Create an item (e.g. Quiz, Survey, Form, or Poll).
Go to the Account Settings
In the Google Tag Manager configuration, click configure and add your GTM ID, then enable the GTM checkbox and click save.
Use the GTM debug mode to map the events in your items that you want to act on to triggers/tags.
You're done!
Note: The GTM integration is part of Business+ plans.
