Obtaining a Temporary Access Key and Security Token Through an Agency
Function
This API is used to obtain a temporary access key and security token by using an agency.
Temporary access keys and security tokens are issued by the system to IAM users, and can be valid for 15 minutes to 24 hours. The temporary access key and security token follow the principle of least privilege. A temporary access key must be used together with a security token, and the x-security-token field must be included in the request header. For details, see How Do I Use a Temporary AK/SK to Sign Requests?
The API can be called using both the global endpoint and region-specific endpoints. For IAM endpoints, see Regions and Endpoints.
