Setting SMS messaging preferences

How to use Amazon SNS to set the DefaultSMSType attribute.

//! Set the default settings for sending SMS messages.
/*!
  \param smsType: The type of SMS message that you will send by default.
  \param clientConfiguration: AWS client configuration.
  \return bool: Function succeeded.

    Aws::SNS::SNSClient snsClient(clientConfiguration);

    Aws::SNS::Model::SetSMSAttributesRequest request;
    request.AddAttributes("DefaultSMSType", smsType);

    const Aws::SNS::Model::SetSMSAttributesOutcome outcome = snsClient.SetSMSAttributes(
            request);

    if (outcome.IsSuccess()) {
        std::cout << "SMS Type set successfully " << std::endl;
    }

Create the client in a separate module and export it.

import { SNSClient } from "@aws-sdk/client-sns";

// The AWS Region can be provided here using the `region` property. If you leave it blank
// the SDK will default to the region set in your AWS config.
export const snsClient = new SNSClient({});

Import the SDK and client modules and call the API.

import { SetSMSAttributesCommand } from "@aws-sdk/client-sns";
import { snsClient } from "../libs/snsClient.js";

/**
 * @param {"Transactional" | "Promotional"} defaultSmsType
 */
export const setSmsType = async (defaultSmsType = "Transactional") => {
  const response = await snsClient.send(
    new SetSMSAttributesCommand({
      attributes: {
        // Promotional – (Default) Noncritical messages, such as marketing messages.
        // Transactional – Critical messages that support customer transactions,
        // such as one-time passcodes for multi-factor authentication.
        DefaultSMSType: defaultSmsType,
      },
    })
  );
  console.log(response);
  // {
  //   '$metadata': {
  //     httpStatusCode: 200,
  //     requestId: '1885b977-2d7e-535e-8214-e44be727e265',
  //     extendedRequestId: undefined,
  //     cfId: undefined,
  //     attempts: 1,
  //     totalRetryDelay: 0
  //   }
  // }
  return response;
};

$SnSclient = new SnsClient([
    'profile' => 'default',
    'region' => 'us-east-1',
    'version' => '2010-03-31'
]);

try {
