Introduction

Last time we talked about Custom Dimensions & Metrics: what they are, how you can use them and saw a basic example. If you recall, we created a custom dimension by using a built-in variable of Google Tag Manager. More specifically, we created a custom dimension in Google Analytics, in which we saved our container ID. But what happens when you don’t have a built-in variable to use?

Glad you asked…

customTask

Let me introduce you to a very interesting concept of Google Tag Manager: customTask. The customTask API is a feature of the Universal Analytics library. It lets you get and set values from the hit as it’s being generated.

As Simo Ahava states on his course:

customTask is special. It has no set functionality of its own. You use it to manipulate the “model” object.
