## Return values
<a name="aws-resource-datazone-domainunit-return-values"></a>

### Ref
<a name="aws-resource-datazone-domainunit-return-values-ref"></a>

When you pass the logical ID of this resource to the intrinsic `Ref` function, `Ref` returns a string containing pipe-separated `DomainId` and `DomainUnitId`, which uniquely identifies a domain unit. For example: \$1 `"Ref": "MyDomainUnit"` \$1 for the resource with the logical ID MyDomainUnit, Ref returns `DomainId|DomainUnitId`. 

For more information about using the `Ref` function, see [https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-ref.html](https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-ref.html).

### Fn::GetAtt
<a name="aws-resource-datazone-domainunit-return-values-fn--getatt"></a>

The `Fn::GetAtt` intrinsic function returns a value for a specified attribute of this type. The following are the available attributes and sample return values.

For more information about using the `Fn::GetAtt` intrinsic function, see [https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-getatt.html](https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-getatt.html).
