Key links:

• Quick Start

Getting started

Currently supported environments

• LTS versions of Node.js

Prerequisites

• You must have an Azure subscription to use this package.
• An existing Communication Services resource. If you need to create the resource, you can use the Azure Portal, the Azure PowerShell, or the Azure CLI.
• See how to register whatsapp business account & create a channel for registering whatsapp channel to your Communication Services resource.

Install the @azure-rest/communication-messages package

Install the Azure CommunicationMessages REST client REST client library for JavaScript with npm:

npm install @azure-rest/communication-messages

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

import MessageClient, { MessagesServiceClient } from "@azure-rest/communication-messages";

const connectionString = `endpoint=https://<resource-name>.communication.azure.com/;accessKey=<Base64-Encoded-Key>`;
const client:MessagesServiceClient = MessageClient(connectionString);

Using AzureKeyCredential

import { AzureKeyCredential } from "@azure/core-auth";
import MessageClient, { MessagesServiceClient } from "@azure-rest/communication-messages";

const endpoint = "https://<resource-name>.communication.azure.com";
const credential = new AzureKeyCredential("<Base64-Encoded-Key>");
const client:MessagesServiceClient = MessageClient(endpoint, credential);

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, or other credential providers provided with the Azure SDK, please install the @azure/identity package:

npm install @azure/identity

The @azure/identity package provides a variety of credential types that your application can use to do this. The README for @azure/identity provides more details and samples to get you started. AZURE_CLIENT_SECRET, AZURE_CLIENT_ID and AZURE_TENANT_ID environment variables are needed to create a DefaultAzureCredential object.

import { DefaultAzureCredential } from "@azure/identity";
import MessageClient, { MessagesServiceClient } from "@azure-rest/communication-messages";

const endpoint = "https://<resource-name>.communication.azure.com";
let credential = new DefaultAzureCredential();
const client:MessagesServiceClient = MessageClient(endpoint, credential);

Send a Template Message with WhatsApp Channel

Note: Business always starts the conversation with a template message.

To send an Template Message, you need add template to your WhatsApp Bussiness Account. For more detail on WhatsApp Template, refer Create and Manage Templates. In below example, we are using

 Template Name: sample_issue_resolution
 Template Language: en_US

 Template Body: "Hi {{1}}, were we able to solve the issue that you were facing?"
 
 With Quick Action Button (Yes, No)

const nameValue:MessageTemplateValue = {
        kind: "text",
        name: "name",
        text: "Arif"
    };

    const yesAction: MessageTemplateValue = {
        kind: "quickAction",
        name: "Yes",
        payload: "Yes"
    };

    const noAction: MessageTemplateValue = {
        kind: "quickAction",
        name: "No",
        payload: "No"
    };

    const templateBindings:MessageTemplateBindings = {
        kind: "whatsApp",
        body: [
            {
                refValue: "name"
            }
        ],
        buttons: [
            {
                subType: "quickReply",
                refValue: "Yes"
            },
            {
                subType: "quickReply",
                refValue: "No"
            }
        ]
    };

    const template:MessageTemplate = {
        name: "sample_issue_resolution",
        language: "en_US",
        bindings: templateBindings,
        values: [nameValue, yesAction, noAction]
    };

    const  result = await client.path("/messages/notifications:send").post({
        contentType: "application/json",
        body: {
            channelRegistrationId: "<Channel_Registration_Id>",
            to: ["<to-phone-number-1>"],
            kind: "template",
            template: template
        }
    });
    if (result.status === "202") {
        const response:Send202Response = result as Send202Response;
        response.body.receipts.forEach((receipt) => {
            console.log("Message sent to:"+receipt.to+" with message id:"+receipt.messageId);
        });
    } else {
        throw new Error("Failed to send message");
    }

Send a Text Message with WhatsApp Channel

Note: Business can't start a conversation with a text message. It needs to be user initiated.

const  result = await client.path("/messages/notifications:send").post({
        contentType: "application/json",
        body: {
            channelRegistrationId: "<Channel_Registration_Id>",
            to: ["<to-phone-number-1>"],
            kind: "text",
            content: "Hello World!!"
        }
    });

 if (result.status === "202") {
        const response:Send202Response = result as Send202Response;
        response.body.receipts.forEach((receipt) => {
            console.log("Message sent to:"+receipt.to+" with message id:"+receipt.messageId);
        });
    } else {
        throw new Error("Failed to send message");
    }

Send a Media Message with WhatsApp Channel

Note: Business can't start a conversation with a media message. It needs to be user initiated.

const  result = await client.path("/messages/notifications:send").post({
        contentType: "application/json",
        body: {
            channelRegistrationId: "<Channel_Registration_Id>",
            to: ["<to-phone-number-1>"],
            kind: "image",
            mediaUri: "https://<your-media-image-file>"
        }
    });

 if (result.status === "202") {
        const response:Send202Response = result as Send202Response;
        response.body.receipts.forEach((receipt) => {
            console.log("Message sent to:"+receipt.to+" with message id:"+receipt.messageId);
        });
    } else {
        throw new Error("Failed to send message");
    }

Troubleshooting

Logging

Enabling logging may help uncover useful information about failures. In order to see a log of HTTP requests and responses, set the AZURE_LOG_LEVEL environment variable to info. Alternatively, logging can be enabled at runtime by calling setLogLevel in the @azure/logger:

const { setLogLevel } = require("@azure/logger");

setLogLevel("info");

For more detailed instructions on how to enable logs, you can look at the @azure/logger package docs.
