Whatsapp Business java api SDK

Whatsapp business api SDK, written in java. This SDK implements the Official Whatsapp Cloud API and WhatsApp Business Management API. These allows you to:

manage your WhatsApp Business Account assets, such as message templates and phone numbers;
send messages to your contacts, such as simple text messages, messages with buttons, video, images, sticker...
upload, delete and retrieve media files.
receive webhooks events

The WhatsApp Business API allows medium and large businesses to communicate with their customers at scale. Using the API, businesses can build systems that connect thousands of customers with agents or bots, enabling both programmatic and manual communication. Additionally, you can integrate the API with numerous backend systems, such as CRM and marketing platforms.The library is designed to be simple and flexible, making it ideal for a wide range of use cases.

This SDK supports WhatsApp Business API versions from v16.0 onwards. See api changelog

👀 Overview

There are two client classes that can be used to interact with the API:

WhatsappBusinessCloudApi, a synchronous/blocking WhatsApp Business Platform Cloud API client;

Send and receive messages using a cloud-hosted version of the WhatsApp Business Platform. The Cloud API allows you to implement WhatsApp Business APIs without the cost of hosting of your own servers and also allows you to more easily scale your business messaging.

 WhatsappApiFactory factory = WhatsappApiFactory.newInstance(TestUtils.TOKEN);

 WhatsappBusinessCloudApi whatsappBusinessCloudApi = factory.newBusinessCloudApi(ApiVersion.V19_0);

WhatsappBusinessManagementApi, a synchronous/blocking WhatsApp Business Management API client;

The WhatsApp Business Management API allows you to programmatically manage your WhatsApp Business Account assets, such as message templates and phone numbers.

WhatsappApiFactory factory = WhatsappApiFactory.newInstance(TOKEN);

WhatsappBusinessManagementApi whatsappBusinessCloudApi = factory.newBusinessManagementApi(ApiVersion.V19_0);

These can be instantiated through the corresponding factory method of WhatsappApiFactory, by passing the token, which can be created following the instructions at whatsapp.

👀 Proxy

You can add a proxy to the api by calling the method setHttpProxy(...) of class WhatsappApiServiceGenerator

public static void setHttpProxy(String host, int port, String username, String pwd)

Call this method before create the api instance like:

// Set http proxy with credentials before the creation of the api instance
WhatsappApiServiceGenerator.setHttpProxy("<YOUR_PROXY_HOST>", "<YOUR_PROXY_PORT>", "<YOUR_PROXY_USERNAME>", "<YOUR_PROXY_PWD>");

// Create the api instance
WhatsappBusinessCloudApi whatsappBusinessCloudApi = factory.newBusinessCloudApi();

📜 Examples (Proxy):

Direct proxy without authentication credentials:

   WhatsappApiFactory factory = WhatsappApiFactory.newInstance(TestConstants.TOKEN);

        // Set http proxy without credentials before the creation of the api instance
        WhatsappApiServiceGenerator.setHttpProxy("localhost", 8080, null,null);
        
        WhatsappBusinessCloudApi whatsappBusinessCloudApi = factory.newBusinessCloudApi();
        var message = MessageBuilder.builder()//
                .setTo(PHONE_NUMBER_1)//
                .buildTextMessage(new TextMessage()//
                        .setBody(Formatter.bold("Hello world!") + "\nSome code here: \n" + Formatter.code("hello world code here"))//
                        .setPreviewUrl(false));

        MessageResponse messageResponse = whatsappBusinessCloudApi.sendMessage(PHONE_NUMBER_ID, message);

        System.out.println(messageResponse);

With authentication credentials:

 WhatsappApiFactory factory = WhatsappApiFactory.newInstance(TestConstants.TOKEN);

        // Set http proxy with credentials before the creation of the api instance
        WhatsappApiServiceGenerator.setHttpProxy("localhost", 8080, "username", "password");
        
        WhatsappBusinessCloudApi whatsappBusinessCloudApi = factory.newBusinessCloudApi();
        var message = MessageBuilder.builder()//
                .setTo(PHONE_NUMBER_1)//
                .buildTextMessage(new TextMessage()//
                        .setBody(Formatter.bold("Hello world!") + "\nSome code here: \n" + Formatter.code("hello world code here"))//
                        .setPreviewUrl(false));

        MessageResponse messageResponse = whatsappBusinessCloudApi.sendMessage(PHONE_NUMBER_ID, message);

        System.out.println(messageResponse);

⬇️ WebHooks

Webhooks are triggered when a customer performs an action or the status for a message a business sends a customer changes.

WebHook objects are mapped on WebHookEvent class

See Whatsapp api documentation for more details. Example:

//payload = the webhook payload json sent by Whatsapp
//using WebHook.constructEvent() to deserialize event
WebHookEvent event = WebHook.constructEvent(payload);

See an example here

You get a webhooks notification:

1- When a customer performs an action

Sends a text message to the business
Sends an image, video, audio, document, or sticker to the business
Sends contact information to the business
Sends location information to the business
Clicks a reply button set up by the business
Clicks a call-to-actions button on an Ad that Clicks to WhatsApp
Clicks an item on a business' list
Updates their profile information such as their phone number
Asks for information about a specific product
Orders products being sold by the business
