Get an IAM user using an AWS SDK

The following code examples show how to get an IAM user.

Warning

To avoid security risks, don't use IAM users for authentication when developing purpose-built software or working with real data. Instead, use federation with an identity provider such as AWS IAM Identity Center (successor to AWS Single Sign-On).

    {
        var response = await _IAMService.GetUserAsync(new GetUserRequest { UserName = userName });
        return response.User;
    }

// UserWrapper encapsulates user actions used in the examples.
// It contains an IAM service client that is used to perform user actions.
type UserWrapper struct {
	IamClient *iam.Client
}



// GetUser gets data about a user.
func (wrapper UserWrapper) GetUser(userName string) (*types.User, error) {
	var user *types.User
	result, err := wrapper.IamClient.GetUser(context.TODO(), &iam.GetUserInput{
		UserName: aws.String(userName),
	})
