This topic describes the details about the request structure, including the endpoints of Security Token Service (STS), communications protocol, HTTP request methods, and request parameters.
For more information about the STS endpoints, see Endpoints.
To ensure communication security, STS only allows you to send requests over HTTPS.
HTTP request methods
STS allows you to send HTTP GET and POST requests.
You must specify the following parameters for each API request:
- The Action parameter. It specifies the operation you want to perform.
- The common request parameters.
- The request parameters that are specific to the specified API operation.
Requests and responses are encoded by using the UTF-8 character set.
