AWS CloudFormation Template Parameter Variables

This topic provides a list of variables supported in AWS CloudFormation template parameters. For general information on variables, see Adding Commander Metadata to Workflows With Variables.

If you need a variable that isn't documented, contact support@snowsoftware.com, and if the variable is available, we'll provide you with the variable name. We'll also add it to the list of documented variables in the next release.
