• 4. Ngrok: Download from ngrok.com to expose your local server to the internet.

Step 2: Download the Chatbot Project

This GitHub repo has over 600 stars and contains everything you need to get started. Just download the complete project and start customizing it.

You can choose one of the following methods:

• 1. Download as ZIP: Click here to download the project , then unzip it anywhere on your computer.
• OR clone with Git:

git clone https://github.com/YonkoSam/whatsapp-python-chatbot.git

2. After downloading or cloning, open your terminal, go to the project folder, and install the required libraries with:

pip install -r requirements.txt

Step 3: Add Your API Keys

In the .env file, paste your actual keys like this:

Where to get them:

Step 4: Run the Bot

Run the chatbot using:

python script.py

Now open a second terminal window and run:

ngrok http 5001

Copy the ngrok URL (like https://abcd1234.ngrok.io) and add /webhook at the end. Then go to your WaSenderAPI dashboard and paste it into the webhook field under your session settings. Select only message_upsert.

Step 5: Customize and Chat

Open persona.json to control how your bot talks. Example:

{
  "name": "Chat Assistant",
  "base_prompt": "You are a friendly and smart assistant. Keep your answers short and helpful."
}
    

Now send a WhatsApp message to the number connected via WaSenderAPI. Your bot will respond automatically!
