For the STS service address, see Service address.
To ensure communication security, the STS service uses only the HTTPS secure channel to send requests.
HTTP request methods
The system allows you to send HTTP GET/POST requests. In this method, the request parameters must be included in the request URL. (The size of a GET request cannot exceed 4 KB, and the size of a POST requests cannot exceed 10 MB.)
You must use an “Action” parameter (such as “AddUser”) in each request to specify the operation to perform, and meanwhile you must add public request parameters and interface-specified request parameters that each operation interface requires.
Requests and responses are encoded using UTF-8.
