# 更新终端节点连接 - UpdateVpcepConnection
#### 功能介绍
终端节点服务（VPC Endpoint Service）通过专属网关，实现跨 VPC 内网访问，可将 VPC 中的服务安全、可靠地提供给其他 VPC 资源使用，无需暴露服务端网络信息，该接口用于更新Elasticsearch/OpenSearch集群的终端节点连接。
#### 调用方法
请参见[如何调用API](https://support.huaweicloud.com/api-css/css_03_0077.html)。
#### 授权信息
账号具备所有API的调用权限，如果使用账号下的IAM用户调用当前API，该IAM用户需具备调用API所需的权限。
- 如果使用角色与策略授权，具体权限要求请参见[权限和授权项](https://support.huaweicloud.com/api-css/css_03_0096.html)。
- 如果使用身份策略授权，需具备如下身份策略权限。
