## Return values
<a name="aws-resource-iot-certificateprovider-return-values"></a>

### Ref
<a name="aws-resource-iot-certificateprovider-return-values-ref"></a>

When you pass the logical ID of this resource to the intrinsic `Ref` function, `Ref` returns the ID of the certificate provider. For example:

 `{ "Ref": "MyCertificateProvider" }` 

A value similar to the following is returned:

 `a1234567b89c012d3e4fg567hij8k9l01mno1p23q45678901rs234567890t1u2` 

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

### Fn::GetAtt
<a name="aws-resource-iot-certificateprovider-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.amazonaws.cn/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-getatt.html](https://docs.amazonaws.cn/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-getatt.html).

#### 
<a name="aws-resource-iot-certificateprovider-return-values-fn--getatt-fn--getatt"></a>

`Arn`  <a name="Arn-fn::getatt"></a>
Returns the Amazon Resource Name (ARN) for the certificate. For example:  
 `{ "Fn::GetAtt": ["MyCertificateProvider", "Arn"] }`   
A value similar to the following is returned:  
 `arn:aws:iot:ap-southeast-2:123456789012:certprovider/my-certificate-provider`
