🤖 Creating a WhatsApp Chatbot with Open AI and Twilio

In this article, we will explore how to connect your WhatsApp number with Open AI to create a chatbot that can answer user queries. We will use Twilio to handle the communication between the chatbot and WhatsApp. By the end of this Tutorial, you will have a fully functional chatbot that can provide accurate responses to user queries.

1. Introduction

Chatbots have become increasingly popular as they offer a convenient way for businesses to interact with their customers. With the advancements in AI and natural language processing, it is now easier than ever to create intelligent chatbots that can understand and respond to user queries effectively. In this tutorial, we will leverage the power of Open AI and Twilio to build a WhatsApp chatbot.

2. Setting up the Environment

Before we dive into the implementation, there are a few things we need to set up. First, you will need an Open AI API key. You can create an account on the Open AI Website and obtain the API key from your account section. Make sure to keep this API key secure as it contains sensitive information.

Next, you will need a Twilio account and a Twilio project. Sign up for a Twilio account and create a new project. In your project settings, you will find the account SID and auth token. These credentials are also sensitive, so make sure not to share them with anyone you don't trust.

3. Creating a WhatsApp Chatbot with Open AI and Twilio

3.1 Obtaining Open AI API Key

To connect your WhatsApp number with Open AI, you will need an API key. Follow the steps Mentioned in your Open AI account section to create a new API key. Remember to keep this key safe and not share it with anyone unauthorized.

3.2 Creating a Twilio Account and Project

In order to handle the communication between the chatbot and WhatsApp, you will need a Twilio account and project. Sign up for a Twilio account if you haven't already and create a new project. In your project settings, you will find the account SID and auth token. These credentials will be required later in the implementation.

3.3 Activating Communication with Twilio WhatsApp

Once you have set up your Twilio account and project, you need to activate communication with Twilio WhatsApp. Follow the instructions provided by Twilio to send a verification code from your WhatsApp account. Once the code is sent and verified, Twilio will allow communication with your WhatsApp number.

3.4 Installing Required Packages

Before running the application, we need to install the required packages. Use a package manager like pip to install the packages listed in the requirements.txt file. This file is provided in the GitHub repository for this tutorial.

3.5 Understanding the Code Structure

The code for our chatbot application is organized into several files. The entry point of the application is run.py, and the main logic is implemented in src/app.py. The Flask application handles two routes: the home route and the receive message route. The Helper module contains helper functions for making requests to Open AI and sending messages using Twilio's APIs.

4. Running the Application

Now that we have set up the environment and understood the code structure, let's run the application and test our chatbot.

4.1 Starting the Flask Server

To run the application locally, open a terminal, navigate to the project directory, and run the command python run.py. This will start the Flask server on your local machine.

4.2 Configuring NGROK

To expose our local environment to the internet, we will use NGROK. Start NGROK on the same port as the Flask server by running the command ngrok http 5000 in a separate terminal.

4.3 Configuring WhatsApp Sandbox

In the Twilio project settings, go to the WhatsApp sandbox configuration. In the "When a message comes in" section, paste the NGROK URL followed by /twilio/receive-message as the URL for incoming messages. Save the configuration.

4.4 Testing the Chatbot

To test the chatbot, send a message to the WhatsApp number associated with your Twilio project. The message will be received by Twilio, which will forward it to your Flask application via NGROK. The application will process the message, generate a response using Open AI, and send the response back to the user through Twilio.

5. Conclusion

In this tutorial, we have learned how to create a WhatsApp chatbot using Open AI and Twilio. We set up the environment, obtained the necessary API keys, implemented the chatbot logic, and tested the application. Chatbots can be a powerful tool for businesses to provide quick and accurate responses to customer queries. With the knowledge gained from this tutorial, you can customize and enhance the chatbot according to your specific requirements.
