### Ref
<a name="aws-resource-bedrock-guardrailversion-return-values-ref"></a>

When you pass the logical ID of this resource to the intrinsic `Ref` function, `Ref` returns the guardrail ID and version, separated by a pipe (`|`) in the format (`guardrail-id|guardrail-version`).

For example, `{ "Ref": "myGuardrailVersion" }` would return the value `"3mzzryddufkp|2"`.

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).
