# AWS::Elasticsearch::Domain DomainEndpointOptions
<a name="aws-properties-elasticsearch-domain-domainendpointoptions"></a>

Specifies additional options for the domain endpoint, such as whether to require HTTPS for all traffic or whether to use a custom endpoint rather than the default endpoint.

**Important**  
The `AWS::Elasticsearch::Domain` resource is being replaced by the [AWS::OpenSearchService::Domain](https://docs.amazonaws.cn/AWSCloudFormation/latest/UserGuide/aws-resource-opensearchservice-domain.html) resource. While the legacy Elasticsearch resource and options are still supported, we recommend modifying your existing Cloudformation templates to use the new OpenSearch Service resource, which supports both OpenSearch and Elasticsearch. For more information about the service rename, see [New resource types](https://docs.amazonaws.cn/opensearch-service/latest/developerguide/rename.html#rename-resource) in the *Amazon OpenSearch Service Developer Guide*.
