```txt

Unknown macro: {hostVar1}.example.com

.foo.example.com
{hostVar1}.example.com

foo.{hostVar1}.example.com

Unknown macro: {hostVar2}.{hostVar1}.example.com
{hostVar2}.{hostVar1}.example.com
```

Hostname variables must comprise the entire domain field and must not be used with other text in the field.

The following format is not supported:

```txt
foo-{hostVar1}.example.com.

foo-{hostVar1}.example.com
```

For more information on how Cloudflare uses variables in API Shield, refer to the examples from [API Discovery](/api-shield/security/api-discovery/).
