You can apply the variables to the template and download the JSON to verify the variables were correctly applied. 

**To apply the new variables and download the parameterized template:** 

1. From the *Parametrized Template* panel, find the attribute to apply the variable.
   For this guide, it's the name of two *DeviceHub Devices* and *Country code*.
