調用API服務后，系統會返回HTTP狀態碼。如果返回的狀態碼為2xx，表示調用成功。如果返回的狀態碼為4xx或5xx，表示調用失敗。本文檔中的返回示例為了便于您查看，做了格式化處理，實際返回結果沒有進行換行、縮進等處理。
正常返回示例
XML示例

<!--結果的根結點-->
<接口名稱+Response>
<!--返回請求標簽-->
<RequestId>4C467B38-3910-447D-87BC-AC049166F216</RequestId>
<!--返回結果數據-->
</接口名稱+Response>JSON示例
{
"RequestId": "4C467B38-3910-447D-87BC-AC049166F216"
}異常返回示例
調用接口出錯后，將不會返回結果數據。調用方可根據每個接口對應的錯誤碼以及公共錯誤碼來定位錯誤原因。
當調用API報錯后，將在response中返回HTTP狀態碼、錯誤碼和錯誤信息，還會包括該次請求在全局的唯一標識RequestId。若您根據錯誤碼和錯誤信息無法明確問題，可將RequestId提供給技術支持人員，幫忙快速定位到該條請求日志。
