Request structure

Last Updated: Jul 03, 2017

Service address

The API access URL for the STS service is:

  1. https://sts.aliyuncs.com

Communication Protocol

  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.)

Request parameters

  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.

Character encoding

  Requests and return results are encoded using the UTF-8 character set.
