Built-in variables

Built-in variables are a special category of variables that are pre-created and non-customizable. New containers have no user-defined variables at the start, and some built-in variables will be pre-enabled. Enabled built-in variables will be made available throughout Tag Manager wherever variable selection menus appear.

To enable built-in variables for a container:

  1. Click Variables in the left menu.
  2. In the Built-In Variables section, click Configure.
  3. Enable or disable variables using their corresponding checkboxes. 
You can also enable built-in variables on the fly in variable selection menus. Select Choose Built In Variable... from any variable selection menu, and then click the desired built-in variable to add it to your container.
