In this article, we will show you how to download Java Facebook Messenger, which is a combination of two things: a Java client for the Facebook Messenger API and a conversational bot using Facebook Messenger and JBot. We will explain what they are, why you should use them, and how to get started with them. Let's begin!
What is Java Facebook Messenger?
Java Facebook Messenger is not an official product from Facebook, but rather a term we use to refer to two open-source projects that enable you to use Facebook Messenger with Java. They are:
A Java client for the Facebook Messenger API
The first project is called . The Facebook Messenger API is a set of web services that allow you to send and receive messages and other events from Facebook users via your own app or bot. The Java client is essentially a thin wrapper around the API, which makes it easier to use in your Java applications. It supports most but not all of the API functionality, such as sending text, image, audio, video, file, template, button, quick reply, and generic messages, as well as receiving message delivery and read receipts, postbacks, referrals, account linking events, and more.

A conversational bot using Facebook Messenger and JBot
The second project is called , which is a framework for making conversational bots using Java. JBot supports multiple platforms, such as Slack, Twitter, Websocket, and of course, Facebook Messenger. JBot makes it easy to create bots that can receive and reply messages, as well as handle complex conversations using dialogs. JBot also provides utilities for natural language processing (NLP), sentiment analysis, spell checking, profanity filtering, and more.

How to download Java Facebook Messenger?
Now that you know the benefits of using Java Facebook Messenger, you might be eager to try it out. In this section, we will show you how to download Java Facebook Messenger in seven easy steps. We will assume that you have some basic knowledge of Java, Maven, and Git, as well as a Facebook account. Let's get started!
Step 1: Clone the GitHub project
The first step is to clone the GitHub project that contains both the Java client for the Facebook Messenger API and the conversational bot with Facebook Messenger and JBot. You can do this by running the following command in your terminal:
git clone
This will create a folder called jbot in your current directory, which contains the source code and other files for the project. You can also download the project as a ZIP file from and extract it to your desired location.
Step 2: Create a Facebook app and a page
The next step is to create a Facebook app and a page that will be used to communicate with your bot. You can do this by following these steps:
Go to and log in with your Facebook account.
Click on Create App in the top right corner and choose Manage Business Integrations as the app type.
Enter a name for your app, such as Java Facebook Messenger, and click on Create App ID.
On the left sidebar, click on Messenger under Products.
Under Access Tokens, click on Add or Remove Pages.
If you already have a page that you want to use for your bot, select it and click on Generate Token. Otherwise, click on Create New Page and follow the instructions to create a new page.
Copy the generated page access token and save it somewhere. You will need it later.
Step 3: Generate a page access token and paste it in application.properties file
The third step is to generate a page access token that will allow your app to send and receive messages from your page. You can do this by following these steps:
In the same Messenger section of your app dashboard, scroll down to Built-In NLP.
Toggle the switch to enable built-in NLP for your page. This will allow your bot to use natural language processing features provided by Facebook.
In your jbot folder, open the file jbot-example/src/main/resources/application.properties.
Paste your page access token in the line that says messenger4j.pageAccessToken=REPLACE_WITH_YOUR_PAGE_ACCESS_TOKEN.
Save the file and close it.
Step 4: Run the example application
The fourth step is to run the example application that comes with the project. This will allow you to test your bot locally before deploying it to a server. You can do this by following these steps:
In your terminal, navigate to the jbot folder and run the following command:
mvn clean install -DskipTests=true
This will build the project and install it in your local repository.
Navigate to the jbot-example folder and run the following command:
mvn spring-boot:run -Dserver.port=8080 -Dmaven.test.skip=true
This will run the example application on port 8080 of your localhost.
In your browser, go to . You should see a page that says Welcome to JBot Example.
Click on the link that says Facebook Messenger Bot. You should see a page that says Facebook Messenger Bot Example.
Scan the QR code with your Facebook Messenger app on your phone or click on the Send Message button to open a chat window with your bot.
Step 5: Set up webhook to receive messages and other events
The fifth step is to set up a webhook that will allow your app to receive messages and other events from Facebook. A webhook is a URL that Facebook will call whenever something happens on your page, such as a user sending a message, clicking a button, or subscribing to your bot. You can do this by following these steps:
In order to set up a webhook, you need to have a public URL for your app that Facebook can access. Since you are running your app locally, you can use a tool like to create a secure tunnel to your localhost.
In your terminal, run the following command:
ngrok http 8080
This will create a public URL for your app, such as Copy this URL and save it somewhere. You will need it later.
In the same Messenger section of your app dashboard, scroll down to Webhooks.
Click on Add Callback URL.
Paste your ngrok URL in the Callback URL field and add /webhook/facebook at the end of it. For example, if your ngrok URL is then your callback URL should be
In the Verify Token field, enter any string that you want, such as jbot. You will need to use the same string in your application.properties file later.
Click on Verify and Save. You should see a green check mark next to your callback URL if everything is OK.
Select the events that you want to subscribe to, such as messages, messaging_postbacks, messaging_optins, etc.
Select the page that you want to subscribe to and click on Subscribe.
In your jbot folder, open the file jbot-example/src/main/resources/application.properties.
Paste your verify token in the line that says messenger4j.verifyToken=REPLACE_WITH_YOUR_VERIFY_TOKEN.
Save the file and close it.
In your terminal, stop and restart the example application by pressing Ctrl+C and running the following command again:
mvn spring-boot:run -Dserver.port=8080 -Dmaven.test.skip=true
This will update your application with the new verify token.
Step 6: Start Step 6: Start messaging your bot or try the jbot-example
The sixth step is to start messaging your bot or try the jbot-example that comes with the project. You can do this by following these steps:
In your Facebook Messenger app on your phone, open the chat window with your bot.
Send a message to your bot, such as Hi, Help, or Menu. You should receive a reply from your bot.
Try different commands and options that your bot offers, such as Weather, Shop, Quiz, etc. You should see various types of messages and attachments, such as text, image, audio, video, file, template, button, quick reply, and generic messages.
If you want to try the jbot-example, which is a sample bot that showcases some of the features of JBot, send a message to your bot with the word jbot. You should see a welcome message from the jbot-example.
Follow the instructions and prompts from the jbot-example to interact with it. You should see how it uses dialogs, NLP, sentiment analysis, spell checking, profanity filtering, and more.
Step 7: Customize your bot by extending the FbBot class
The seventh and final step is to customize your bot by extending the FbBot class. The FbBot class is an abstract class that provides methods for handling different types of events and messages from Facebook. You can override these methods to implement your own logic and functionality for your bot. You can do this by following these steps:
In your jbot folder, open the file jbot-example/src/main/java/example/jbot/facebook/FbBot.java.
This is the class that extends the FbBot class and implements the methods for handling different types of events and messages from Facebook.
You can modify this class to customize your bot according to your needs and preferences. For example, you can change the welcome message, add new commands and options, use different types of messages and attachments, call external APIs or services, etc.
You can also create new classes that extend the FbBot class and register them in the jbot-example/src/main/java/example/jbot/facebook/FbBotApplication.java file.
Save your changes and restart your example application to see them in action.
