What are data layer variables in Google Tag Manager?

Variables in Google Tag Manager are named placeholders for values that are populated when code is run on your website, such as the value of an order.

If you are not familiar with variables and other Google Tag Manager components, see more here.

When your Grow Order Created event in the Google Tag Manager, you will also need to pass the Order ID and Order price in the event. The way to do that is by entering the appropriate variables in the event code.

If you are already using Google Tag Manager for conversion tracking or for any other tool, it is very likely you already have these variables set up in your Google Tag Manager container.

To check the variables in your Google Tag Manager container, click on “Variables” on the left-hand menu in your Google Tag Manager container.
