This topic describes the request structure used when you call API operations of Auto Scaling.
Endpoints
To reduce network latency, we recommend that you configure endpoints based on your business location. The following table describes the endpoints of Auto Scaling.

Request method
The HTTP GET method is supported for sending requests. When using the HTTP GET method, you must include the request parameters in the URL of the request.
Request parameters
In each request, you must specify the operation that you want to perform by using the Action parameter, such as CreateScalingGroup. You must also specify the common request parameters and operation-specific parameters.
You can call API operations by sending HTTP or HTTPS requests. For a higher level of security, we recommend that you send requests over HTTPS.
Requests and responses are encoded in UTF-8.
