# 创建防护域名 - CreateDomain
#### 功能介绍
创建防护域名
#### 调用方法
请参见[如何调用API](https://support.huaweicloud.com/api-aad/aad_02_0007.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-aad/abcd.html)。
- 如果使用身份策略授权，当前API调用无需身份策略权限。
