get_caller_identity

STS.Client.get_caller_identity()

Returns details about the IAM user or role whose credentials are used to call the operation.

Note

No permissions are required to perform this operation. If an administrator adds a policy to your IAM user or role that explicitly denies access to the sts:GetCallerIdentity action, you can still perform this operation. Permissions are not required because the same information is returned when an IAM user or role is denied access. To view an example response, see I Am Not Authorized to Perform: iam:DeleteVirtualMFADevice in the IAM User Guide .
