This topic introduces the request structure.
The access address for the Auto Scaling API service is ess.aliyuncs.com.
The system supports request communication through the HTTP or HTTPS channel. We recommend that you send requests over HTTPS for enhanced security.
The system allows you to send HTTP GET requests. This requires request parameters to be included in the request URL.
For each request, you must specify the operation you want to execute, namely the Action parameter (for example, CreateScalingGroup), and each operation must contain the public and specific request parameters of the specified operation.
Requests and returned results are encoded using the UTF-8 character set.
