'SenderID' issues sending SMS on Amazon SNS (Official PHP SDK)

Question

For some reason the SenderID seems to revert to NOTICE - see here when I set the SenderID in the code.

When I leave the SenderID variable out, it sends as the default set - this is good, but we will be occasionally changing the name for different uses.

I am using the Official PHP SDK, with the code below:

$aws_cred = array(
    'credentials' => array(
        'key' => 'GOT THE KEY',
        'secret' => 'GOT THE SECRET',
    ),
    'region' => 'eu-west-1', // < your aws from SNS Topic region
    'version' => 'latest'
    );
    $sns = new \Aws\Sns\SnsClient($aws_cred);

    $args = array(
    "SenderID" => "MySendID",
    "SMSType" => "Promotional",
    "Message" => "Amazon y u do dis??",
    "PhoneNumber" => "+number"
    );

    $result = $sns->publish($args);

I am sending to the UK (so SID works there), and also it is within the 11 character limit.

Does anyone have any idea why this is happening?

Cheers

I have found the answer.

The search system didn't materialise this originally, but finally, I have found it.

I found the solution. Set the args this way. It works!

$args = array(
    'MessageAttributes' => [
          'AWS.SNS.SMS.SenderID' => [
               'DataType' => 'String',
               'StringValue' => 'YourSenderName'
        ]
     ],
      "SMSType" => "Transactional",
      "PhoneNumber" => "+87654321",
      "Message" => "Hello World!"
);
