How to handle async response in aws sns publish notification

[kcs-nareshramoliya]

I have used this for push notification and its working fine but when I publish push notification control goes over and I can't perform database operation after publish call. So how to handle the asynchronous call. Is it possible using Guzzle promise to wait for response?

$sns->publish(array( //Async
                                'TargetArn' => $userDeviceToken->sns_arn,
                                'MessageStructure' => 'json',
                                'Message' => json_encode(array(
                                    'default' => '',
                                    'APNS_SANDBOX' => json_encode(array(
                                        'aps' => array(
                                            'alert' => array(
                                                'body' => $notificationMessage,
                                                'title' => $notificationTitle,
                                            )
                                        ),
                                        'badge' => '0',
                                        'sound' => 'default',
                                        'content-available' => '1'
                                    ))
                                ))

I want to perform db operation after all the notification publish and sent.

Hi @nareshramoliya, thanks for reaching out to us. Messages can be published asynchronously to SNS using the publishAsync() method, which returns a Guzzle promise for which you can wait() for a response.

$promise = $sns->publishAsync([
    'TargetArn' => $topicArn,
    'Message' => $message,
    'Subject' => $subject
]);

$promise->wait();
