## Additional Configuration Variables

In addition to the Standard Journey data, Theme variants and configuration properties are also available. Any of your theme variables can be accessed using the **theme** namespace. Configuration variables are available on the **configuration** namespace. Finally, custom profile variables and app specific configurations are available on **profile**. We recommend exploring these in App Preview to further see what data you have available.
