# Configuration Versions API

A configuration version represents versions of Terraform configuration.
Each set of changes to Terraform HCL files or the scripts
used in the files should have an associated configuration version.

When creating versions via the API, the variables attribute can be sent
to include the necessary variables for the Terraform configuration.

### Configuration Version Attributes
