# 查询AOM2.0相关云服务授权信息 - ListPermissions
#### 功能介绍
该接口用于查询AOM2.0相关云服务授权信息。
#### 调用方法
请参见[如何调用API](https://support.huaweicloud.com/api-aom/aom_04_0057.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-aom/aom_04_0031.html)。
- 如果使用身份策略授权，需具备如下身份策略权限。
  
  | 授权项            | 访问级别 | 资源类型（\*为必须） | 条件键 | 别名 | 依赖的授权项 |
  |:---|:---|:---|:---|:---|:---|
  | aom:agency:get | Read | -           | -   | -  | -      |
