How to send push notification from web to iOS and android device using AWS SNS in Laravel 5.1?

I have coded like,

$sns = App::make('aws')->createClient('sns');

    $data = json_encode([
        'APNS' => ['apns' => [
                'alert' => $message
            ]
        ]
    ]);

    Log::info($data);

    $sns->publish(array(
        'Message' => $data,
        'TargetArn' => "arn:aws:sns:us-west-2:360542326270:endpoint/APNS_SANDBOX/Testtest/20a75cd1-da25-3331-8126-4db497cbdd5e"
    ));

I'am getting the error as below:

[Aws\Sns\Exception\SnsException]
