Getting started

Prerequisites

Adding the package to your product

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-messages</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-messages</artifactId>
    <version>1.0.0</version>
</dependency>

Key concepts

Then SDK provides two clients and each client can be async client or normal client:

  • NotificationMessageClient or NotificationMessageAsyncClient provide operation to send message (text, media or template) and download media file from Whatsapp for given mediaId which we receive in incoming message event (User to Business Flow).
  • MessageTemplateClient or MessageTemplateAsyncClient provide operation to fetch template list for given channel.

Authentication

You can get a key and/or connection string from your Communication Services resource in Azure Portal. Once you have a key, you may authenticate with any of the following methods:

Using a connection string

NotificationMessagesClient notificationClient = new NotificationMessagesClientBuilder()
    .connectionString("<CONNECTION_STRING>")
    .buildClient();

MessageTemplateClient messageTemplateClient = new MessageTemplateClientBuilder()
    .connectionString("<CONNECTION_STRING>")
    .buildClient();

Using AzureKeyCredential

String endpoint = "https://<resource-name>.communication.azure.com";
AzureKeyCredential azureKeyCredential = new AzureKeyCredential("<access-key>");
NotificationMessagesClient notificationClient = new NotificationMessagesClientBuilder()
    .endpoint(endpoint)
    .credential(azureKeyCredential)
    .buildClient();

String endpoint = "https://<resource-name>.communication.azure.com";
AzureKeyCredential azureKeyCredential = new AzureKeyCredential("<access-key>");
MessageTemplateClient messageTemplateClient = new MessageTemplateClientBuilder()
    .endpoint(endpoint)
    .credential(azureKeyCredential)
    .buildClient();

Using Azure Active Directory managed identity

Client API key authentication is used in most of the examples, but you can also authenticate with Azure Active Directory using the Azure Identity library. To use the DefaultAzureCredential provider shown below,

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

String endpoint = "https://<resource-name>.communication.azure.com";
TokenCredential credential = new DefaultAzureCredentialBuilder().build();
NotificationMessagesClient notificationClient =  new NotificationMessagesClientBuilder()
    .endpoint(endpoint)
    .credential(credential)
    .buildClient();

String endpoint = "https://<resource-name>.communication.azure.com";
TokenCredential credential = new DefaultAzureCredentialBuilder().build();
MessageTemplateClient messageTemplateClient = new MessageTemplateClientBuilder()
    .endpoint(endpoint)
    .credential(credential)
    .buildClient();
