<a name="API_GetResponseHeadersPolicy"></a>

To get a response headers policy, you must provide the policy's identifier. If the response headers policy is attached to a distribution's cache behavior, you can get the policy's identifier using `ListDistributions` or `GetDistribution`. If the response headers policy is not attached to a cache behavior, you can get the identifier using `ListResponseHeadersPolicies`.
