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.
 */
bool AwsDoc::SNS::setSMSType(const Aws::String &smsType,
                             const Aws::Client::ClientConfiguration &clientConfiguration) {
    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;
    }
    else {
        std::cerr << "Error while setting SMS Type: '"
                  << outcome.GetError().GetMessage()
                  << "'" << std::endl;
    }

    return outcome.IsSuccess();
}

#### [ CLI ]

**AWS CLI**  
**To set SMS message attributes**  
The following `set-sms-attributes` example sets the default sender ID for SMS messages to `MyName`.  

```
aws sns set-sms-attributes \
    --attributes DefaultSenderID=MyName
```
This command produces no output.

#### [ JavaScript ]

**SDK for JavaScript (v3)**

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);
