# 域名&鉴权\&APPID ### 1、**API 域名** ### 2、接口鉴权登录KYT系统后，在帐号设置页面，可以获取apikey和secretkey。在请求接口时，为了保障安全性，除了传递apikey，还需要按规定的算法进行加密签名。并在header中传递时间戳timestamp和签名sign参数。

#### Header参数


参数名	数据类型	是否必传	描述
timestamp	int	true	时间戳（单位s）
sign	string	true	签名计算方式：sha256("timestamp={时间戳}&secret={secretkey}") 在线加密工具：https://crypot.51strive.com/sha256.html 示例：加密前： timestamp=1677148682&secret=9e3df800bbcbb1b8fc97bf78ed95a95a92aa3a155d270f1e48eb330c2d435321 加密后： 110a20dcbe1fef5456051a8887c8d1aeba637bbc624e606697fb82a7e7ded604
