Google Tag Manager
With the Google Tag Manager (GTM) integration, you can intercept every event that occurs in your item and trigger actions accordingly. For example, you can fire different pixels for different answers to a question or you can fire a pixel each time a user submits a response.
How to setup
1) In your Opinion Stage account, open account settings, enable the Google Tag Manager (GTM) feature, enter your GTM ID, and click Save.
2) Use Google Tag Manager’s Preview/Debug mode while submitting an entry in your item to identify and map the events you want to use for triggers and tags.
For more details, refer to the GTM help file.
