在芯片设计行业，ETX是常见的远程访问环境。用户在通过ETX访问远程环境前必须首先加入ETX系统，然后通过profile分配相关的环境的访问权限。

通常这些操作在ETX WEB页面手工操作，如果我们期望实现用户帐号注册全自动化，就需要将以上操作通过脚本来实现。

经过调查发现ETX提供了REST访问接口，因此帐号注册全自动化就可以实现。

主要流程如下：

在调用ETX REST接口前还需要获取ETX API的URL以及访问密钥。登录ETX后，点击右上部用户头像旁边的齿轮图标，在用户设置中选择创建 API keys即可生成ETX API访问密钥。 

 ETX登录界面左上角选择 REST API即可显示所有ETX API，点击还可查看API的详细说明和示例。

通过 Python 自动创建ETX帐号的示例代码如下：
