Explanation:
The Query API for IAM and AWS STS lets you call service actions. Query API requests are HTTPS requests that must contain an Action parameter to indicate the action to be performed. IAM and AWS STS support GET and POST requests for all actions, that is, the API does not require you to use GET for some actions and POST for others.
