AWS-PHP-SDK / SNS direct addressing returns error

Question

Hi I am using Laravel 4 setup to make use of AWS SNS to send a push message to my iOS device, the publish command to my device works well from AWS console.

I then tried from PHP:

    $sns = AWS::get('sns');

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

I am getting

Guzzle \ Service \ Exception \ ValidationException Validation errors: [TopicArn] is a required string: The topic you want to publish to.

but the docs specifically say I can use publish to either send to a topic ARN or use direct addressing to send to a single device directly.

it seems the AWS PHP SDK forces me to use TopicArn anyway.

what am I doing wrong?

What version of the SDK and Guzzle do you have installed? – Fluvial

I ask because I cannot reproduce the error. I copied your code and ran it, but the Guzzle validation succeeds just fine as it should. – Fluvial

I have composer doing that for me, I had "guzzle/guzzle": "3.6.*" and now I added "aws/aws-sdk-php-laravel": "1.*". so I got Guzzle 3.6.0 and AWS-PHP-SDK 2.3.4 – Failing

worked.. see answer below – Failing

Answer 1

I just removed the explicit guzzle line from composer. then ran update, it removed guzzle 3.6 and installed 3.9. it then removed AWS-PHP-SDK 2.3.4 and installed dev-master

I then tried it and it worked.

not sure what was the problem, but different packages versions did not work together...

The problem is that version 2.3.4 of the SDK did not yet support mobile push notifications, so the TopicArn was required at that time. – Fluvial

It's good to explicitly declare your dependencies in your project's composer.json, for example: {"aws/aws-sdk-php-laravel": "~1.1", "aws/aws-sdk-php": "~2.6", "guzzle/guzzle": "~3.9.0"}, and stay up-to-date, especially with the SDK. – Fluvial
