In this blog post, we will guide you through the easy steps to build your very own WhatsApp bot using Python, making the process accessible even for beginners!

Create a WhatsApp Bot Using Python Easily

Prerequisites

Before starting, you will need the following:

Step 1: Set Up Your Twilio Account

To send messages on WhatsApp, you need to create a Twilio account and configure WhatsApp:

  • Sign up at Twilio's website.
  • Navigate to the Twilio Console and activate your free trial.
  • Request access to the Twilio Sandbox for WhatsApp under the "Messaging" section.
  • Follow the instructions to link your WhatsApp number with the Twilio Sandbox.

Step 2: Install Required Libraries

Use pip to install the required libraries. Open your terminal and run:

pip install twilio flask

Step 3: Create Your Python Script

Open your favorite code editor and create a new Python file named whatsapp_bot.py. Below is a sample code to get you started:


from flask import Flask, request
from twilio.twiml.messaging_response import MessagingResponse

app = Flask(__name__)

@app.route("/whatsapp", methods=['POST'])
def whatsapp_bot():
    msg = request.form.get('Body')
    response = MessagingResponse()
    response.message(f"You said: {msg}")
    return str(response)

if __name__ == "__main__":
    app.run(debug=True)

Step 4: Expose Your Local Server

To send messages from WhatsApp to your Flask application, you need to expose your local server to the internet using a service like Ngrok:

  • Download and install Ngrok.
  • Run the following command in your terminal:
    • ngrok http 5000
  • Copy the forwarding URL provided by Ngrok.

Step 5: Configure Twilio Webhook

Go back to your Twilio console and navigate to the Sandbox settings:

  • Paste the Ngrok URL followed by /whatsapp into the "When a message comes in" field.
  • Click "Save" to update the webhook.

Step 6: Run Your Bot

Run your Python script by executing:

python whatsapp_bot.py

Now you can send messages to your Twilio Sandbox number, and the bot will respond back!
