Qualifio data layer

T.V -

In the header of every page of a Qualifio campaign is a small script. This script is the Qualifio data layer (qlfDataLayer). A data layer is an object that contains all of the information that you might want to pass to various tools for analytics and/or marketing tags. The data layer is the source of a vast amount of customer interaction data, website-related data and campaign data, which can fuel a tag management system such as Google Tag Manager and power additional tracking vendors like Google Analytics.

What does a data layer look like?

<script>qlfDataLayer = [{"device":"desktop","optins":[],"form_submitted":0,"isWinner":"null","domain":"demo.qualifioapp.com","query_string":"","channel_guid":"B4221247-9CE4-4F3C-8255-1DB9FA3BE552","step":"questionset","thematics":[],"campaign_id":123456,"campaign_guid":"54973303-E076-4C85-94FA-63F68D780181","pgi":1,"parentURL":"https://qualifio.com/product/campaign-formats/quiz/","isIdentified":1,"lg":"en","title":"My demo campaign","score":0,"preview":false,"page_path":"/123456/en/1/questionset/1","pg":1}]</script>

This data layer can be used by any JavaScript (for instance the ones of Google Analytics or Tag Manager).
