调用API服务后，系统会返回HTTP状态码。如果返回的状态码为2xx，表示调用成功。如果返回的状态码为4xx或5xx，表示调用失败。本文档中的返回示例为了便于您查看，做了格式化处理，实际返回结果没有进行换行、缩进等处理。
正常返回示例
XML示例
<?xml version="1.0" encoding="UTF-8"?>
<!--结果的根结点-->
<接口名称+Response>
<!--返回请求标签-->
<RequestId>4C467B38-3910-447D-87BC-AC049166F216</RequestId>
<!--返回结果数据-->
</接口名称+Response>JSON示例
{
"RequestId": "4C467B38-3910-447D-87BC-AC049166F216"
}异常返回示例
调用接口出错后，将不会返回结果数据。调用方可根据每个接口对应的错误码以及公共错误码来定位错误原因。
当调用API报错后，将在response中返回HTTP状态码、错误码和错误信息，还会包括该次请求在全局的唯一标识RequestId。若您根据错误码和错误信息无法明确问题，可将RequestId提供给技术支持人员，帮忙快速定位到该条请求日志。
XML示例（请求过期）
<KMS>
<HttpStatus>400</HttpStatus>
<Code>IllegalTimestamp</Code>
<Message>The input parameter "Timestamp" that is mandatory for processing this request is not supplied.</Message>
