# Configuration 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. A configuration
represents settings associated with a resource that runs Terraform with versions
of Terraform configuration. Configurations have many configuration versions
which represent versions of Terraform configuration templates and other
associated configuration. Most operations take place on the configuration
version, not the configuration.

## Get Latest Configuration Version

This endpoint gets the latest configuration version.

- `:username` `(string: <required>)` - Specifies the username or organization
  name under which to get the latest configuration version. This username must

```

### Sample Response

```json
{
  "version": {
    "version": 6,

      "foo": "bar"
    },
    "tf_vars": [],
    "variables": {}
  }
}
```

- `version` `(int)` - the unique version instance number.

- `metadata` `(map<string|string>)` - a map of arbitrary metadata for this
