How to Use WhatsApp API in Android Studio?

WhatsApp has become one of the most popular messaging platforms worldwide, and many developers are looking for ways to integrate it into their Android applications. Luckily, WhatsApp provides an API that allows developers to incorporate its features seamlessly. In this tutorial, we will explore how to use the WhatsApp API in Android Studio.


In order to use the WhatsApp API in your Android application, you need to have the following prerequisites:

  • Android Studio: Make sure you have Android Studio installed on your system. You can download it from the official Android website.
  • WhatsApp Business Account: You need a WhatsApp Business account in order to access the API.

    If you don’t have one, create a new account on the WhatsApp Business website.

  • WhatsApp Business API Client: Download and install the WhatsApp Business API client on your system. This client allows you to connect with the WhatsApp servers and access the API.

Setting Up Your Project

To get started, follow these steps:

  1. Create a new project in Android Studio by going to File > New > New Project. Choose an appropriate name and package for your application.
  2. Add the necessary dependencies to your project’s build.gradle file. Open the file and add the following lines of code:
    // Other dependencies..
    implementation 'com.twilio:twilio-java-sdk:7.55.+'

In this example, we are using Twilio’s Java SDK for interacting with the WhatsApp API. Feel free to explore other libraries if you prefer.

Initializing the WhatsApp API Client

Once you have set up your project, it’s time to initialize the WhatsApp API client. Follow these steps:

  1. Import the necessary classes in your Java file:
import com.twilio.Twilio;
import com.RestClient;
import com.http.TwilioRestClient;
import com.TwilioRestClient.Builder;
import com.type.PhoneNumber;
  1. Add the following code snippet to initialize the WhatsApp API client:
// Your Account SID from
String accountSid = "YOUR_ACCOUNT_SID";
// Your Auth Token from
String authToken = "YOUR_AUTH_TOKEN";

// Initialize the Twilio REST client
Twilio.init(accountSid, authToken);

Make sure to replace “YOUR_ACCOUNT_SID” and “YOUR_AUTH_TOKEN” with your actual Twilio account SID and auth token.

Sending a WhatsApp Message

To send a message using the WhatsApp API, follow these steps:

  1. Add the following code snippet to send a message:
// Create a new message
Message message = Message.creator(
                new PhoneNumber("TO_PHONE_NUMBER"), // Destination phone number
                new PhoneNumber("FROM_PHONE_NUMBER"), // Your Twilio phone number
                "Hello from your Android application!") // Message content

// Output the message SID for reference

Replace “TO_PHONE_NUMBER” with the recipient’s phone number and “FROM_PHONE_NUMBER” with your Twilio phone number. Also, modify the message content as per your requirements.

Running Your Application

Before running your application, make sure you have set up a virtual device or connected a physical device to your system. After that, click on the Run button in Android Studio to launch your application.

Once the application is running, you should see the WhatsApp message being sent to the specified recipient. You can also check the Twilio console for any error messages or logs related to the API requests.
