Use DeleteUser with an Amazon SDK or CLI

        Aws::Client::ClientConfiguration clientConfig;
        // Optional: Set to the AWS Region (overrides config file).
        // clientConfig.region = "us-east-1";

    Aws::CognitoIdentityProvider::CognitoIdentityProviderClient client(clientConfig);

        Aws::CognitoIdentityProvider::Model::DeleteUserRequest request;
        request.SetAccessToken(accessToken);

        Aws::CognitoIdentityProvider::Model::DeleteUserOutcome outcome =
                client.DeleteUser(request);

        if (outcome.IsSuccess()) {
            std::cout << "The user " << userName << " was deleted."
                      << std::endl;
        }
        else {
            std::cerr << "Error with CognitoIdentityProvider::DeleteUser. "
                      << outcome.GetError().GetMessage()
                      << std::endl;
        }

To delete a user

This example deletes a user.

Command:

aws cognito-idp delete-user --access-token ACCESS_TOKEN

	"github.com/aws/aws-sdk-go-v2/service/cognitoidentityprovider"
	"github.com/aws/aws-sdk-go-v2/service/cognitoidentityprovider/types"
)

type CognitoActions struct {
	CognitoClient *cognitoidentityprovider.Client
}



// DeleteUser removes a user from the user pool.
func (actor CognitoActions) DeleteUser(ctx context.Context, userAccessToken string) error {
	_, err := actor.CognitoClient.DeleteUser(ctx, &cognitoidentityprovider.DeleteUserInput{
		AccessToken: aws.String(userAccessToken),
	})
	if err != nil {
		log.Printf("Couldn't delete user. Here's why: %v\n", err)
	}
	return err
}

export const deleteUser = async ({ region, accessToken }) => {
