在使用RAM账号调用SLB API前，需要主账号通过创建授权策略对RAM账号进行授权。在授权策略中，使用资源描述符（Alibaba Cloud Resource Name, ARN）指定授权资源。

可授权的负载均衡资源类型

在进行RAM子账号授权时，SLB资源的描述方式如下：

资源类型 授权策略中的资源描述方法
LoadBalancer acs:slb:$regionid:$accountid:loadbalancer/$loadbalancerid
acs:slb:$regionid:$accountid:loadbalancer/*
acs:slb:*:$accountid:loadbalancer/*
acs:slb:*:*:loadbalancer/*
Certificate acs:slb:$regionid:$accountid:certificate/$servercertificateId
acs:slb:$regionid:$accountid:certificate/*

其中$regionid/accoutid/servercertificateId 为具体的资源ID，*代表对应的所有资源。

可授权的SLB接口

下表列举了SLB中可授权的API及其描述方式：
