You can send all events that occur in your Quizzes/Surveys 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 a Quiz/Survey and embed it on a page that includes your GTM on it
Send us your GTM ID so we can integrate it into your Opinion Stage account. Once your GTM ID is integrated in the Opinion Stage account, all events in the Quiz/Survey (e.g. start button clicked, option X in question Y clicked, etc) will be sent to the GTM on the hosting page
Use the GTM debug mode to map the events in the Quiz/Survey you want to act on to triggers/tags
