Getting started

Prerequisites

Include the package

Include the BOM file

Please include the azure-sdk-bom to your project to take dependency on the General Availability (GA) version of the library. In the following snippet, replace the {bom_version_to_target} placeholder with the version number. To learn more about the BOM, see the AZURE SDK BOM README.

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>com.azure</groupId>
            <artifactId>azure-sdk-bom</artifactId>
            <version>{bom_version_to_target}</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

and then include the direct dependency in the dependencies section without the version tag.

<dependencies>
  <dependency>
    <groupId>com.azure</groupId>
    <artifactId>azure-communication-sms</artifactId>
  </dependency>
</dependencies>

Include direct dependency

If you want to take dependency on a particular version of the library that is not present in the BOM, add the direct dependency to your project as follows.

<dependency>
  <groupId>com.azure</groupId>
  <artifactId>azure-communication-sms</artifactId>
  <version>1.1.29</version>
</dependency>

Authenticate the client

Azure Active Directory Token Authentication

A DefaultAzureCredential object must be passed to the SmsClientBuilder via the credential() function. Endpoint and httpClient must also be set via the endpoint() and httpClient() functions respectively.

AZURE_CLIENT_SECRET, AZURE_CLIENT_ID and AZURE_TENANT_ID environment variables are needed to create a DefaultAzureCredential object.

// You can find your endpoint and access key from your resource in the Azure Portal
String endpoint = "https://<RESOURCE_NAME>.communication.azure.com";

SmsClient smsClient = new SmsClientBuilder()
    .endpoint(endpoint)
    .credential(new DefaultAzureCredentialBuilder().build())
    .buildClient();

Access Key Authentication

SMS uses HMAC authentication with the resource access key. The access key must be provided to the SmsClientBuilder via the credential() function. Endpoint and httpClient must also be set via the endpoint() and httpClient() functions respectively.

// You can find your endpoint and access key from your resource in the Azure Portal
String endpoint = "https://<resource-name>.communication.azure.com";
AzureKeyCredential azureKeyCredential = new AzureKeyCredential("<access-key>");

SmsClient smsClient = new SmsClientBuilder()
    .endpoint(endpoint)
    .credential(azureKeyCredential)
    .buildClient();

Alternatively, you can provide the entire connection string using the connectionString() function instead of providing the endpoint and access key.

// You can find your connection string from your resource in the Azure Portal
String connectionString = "https://<resource-name>.communication.azure.com/;<access-key>";

SmsClient smsClient = new SmsClientBuilder()
    .connectionString(connectionString)
    .buildClient();

Key concepts

There are two different forms of authentication to use the Azure Communication SMS Service.

Examples

Send a 1:1 SMS Message

Use the send or sendWithResponse function to send an SMS message to a single phone number.

SmsSendResult sendResult = smsClient.send(
    "<from-phone-number>",
    "<to-phone-number>",
    "Weekly Promotion");

System.out.println("Message Id: " + sendResult.getMessageId());
System.out.println("Recipient Number: " + sendResult.getTo());
System.out.println("Send Result Successful:" + sendResult.isSuccessful());

Send a 1:N SMS Message

To send an SMS message to a list of recipients, call the send or sendWithResponse function with a list of recipient phone numbers. You may also add pass in an options object to specify whether the delivery report should be enabled and set custom tags.

SmsSendOptions options = new SmsSendOptions();
options.setDeliveryReportEnabled(true);
options.setTag("Marketing");

Iterable<SmsSendResult> sendResults = smsClient.sendWithResponse(
    "<from-phone-number>",
    Arrays.asList("<to-phone-number1>", "<to-phone-number2>"),
    "Weekly Promotion",
    options /* Optional */,
    Context.NONE).getValue();

for (SmsSendResult result : sendResults) {
    System.out.println("Message Id: " + result.getMessageId());
    System.out.println("Recipient Number: " + result.getTo());
    System.out.println("Send Result Successful:" + result.isSuccessful());
}

Troubleshooting

SMS operations will throw an exception if the request to the server fails. Exceptions will not be thrown if the error is caused by an individual message, only if something fails with the overall request. Please use the isSuccessful() flag to validate each individual result to verify if the message was sent.

try {
    SmsSendOptions options = new SmsSendOptions();
    options.setDeliveryReportEnabled(true);
    options.setTag("Marketing");

    Response<Iterable<SmsSendResult>> sendResults = smsClient.sendWithResponse(
        "<from-phone-number>",
        Arrays.asList("<to-phone-number1>", "<to-phone-number2>"),
        "Weekly Promotion",
        options /* Optional */,
        Context.NONE);

    Iterable<SmsSendResult> smsSendResults = sendResults.getValue();
    for (SmsSendResult result : smsSendResults) {
        if (result.isSuccessful()) {
            System.out.println("Successfully sent this message: " + result.getMessageId() + " to " + result.getTo());
        } else {
            System.out.println("Something went wrong when trying to send this message " + result.getMessageId() + " to " + result.getTo());
            System.out.println("Status code " + result.getHttpStatusCode() + " and error message " + result.getErrorMessage());
        }
    }
} catch (RuntimeException ex) {
    System.out.println(ex.getMessage());
}
