## Contents

 ** CallerReference **   <a name="cloudfront-Type-CloudFrontOriginAccessIdentityConfig-CallerReference"></a>
A unique value (for example, a date-time stamp) that ensures that the request can't be replayed.  
If the value of `CallerReference` is new (regardless of the content of the `CloudFrontOriginAccessIdentityConfig` object), a new origin access identity is created.  
If the `CallerReference` is a value already sent in a previous identity request, and the content of the `CloudFrontOriginAccessIdentityConfig` is identical to the original request (ignoring white space), the response includes the same information returned to the original request.  
If the `CallerReference` is a value you already sent in a previous request to create an identity, but the content of the `CloudFrontOriginAccessIdentityConfig` is different from the original request, CloudFront returns a `CloudFrontOriginAccessIdentityAlreadyExists` error.

 ** Comment **   <a name="cloudfront-Type-CloudFrontOriginAccessIdentityConfig-Comment"></a>
