# 更新用户（组）与IAM委托的映射关系-UpdateAgencyMapping
#### 功能介绍
更新用户（组）与IAM委托之间的映射关系，用于配置集群访问外部云服务资源时的权限委托。与查询用户（组）与IAM委托的映射关系接口配合使用，可验证更新结果。
#### 接口约束
无
#### 调用方法
请参见[如何调用API](https://support.huaweicloud.com/api-mrs/zh-cn_topic_0013582897.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-mrs/mrs_02_0221.html)。
- 如果使用身份策略授权，需具备如下身份策略权限。
