FastAPI Twilio Webhook Handler

This project is a FastAPI application designed to handle incoming webhooks from Twilio. It processes messages and responds with a formatted XML response.

Features

• Validates incoming requests from Twilio.
• Processes user queries and generates responses.
• Returns responses in XML format suitable for Twilio.

Prerequisites

• Python 3.7 or higher
• FastAPI
• Uvicorn (ASGI server)
• Ngrok (for exposing local server to the internet)
• Twilio account for testing webhooks

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/your-repo-name.git
   cd your-repo-name

2. Create a virtual environment:

   python -m venv venv
   source venv/bin/activate  # On Windows use `venv\Scripts\activate`

3. Install dependencies:

   pip install -r requirements.txt

Configuration

1. Environment Variables:

   Create a .env file in the root directory and add your Twilio credentials and any other necessary configuration:

   TWILIO_ACCOUNT_SID=your_account_sid
   TWILIO_AUTH_TOKEN=your_auth_token
   

2. Ngrok Setup:

   Download and install Ngrok from ngrok.com. Use it to expose your local server to the internet:

   ngrok http 8000

   Note the forwarding URL provided by Ngrok (e.g., http://e868-2a09-bac0-1000-41c-00-238-2a.ngrok-free.app) and configure it in your Twilio webhook settings.

Running the Application

1. Start the FastAPI server:

   uvicorn main:app --reload

   This will start the server on http://127.0.0.1:8000.

2. Set up Twilio Webhook:

   In your Twilio console, set the webhook URL to the Ngrok forwarding address followed by /webhook/twilio.

Usage

• Webhook Endpoint:

  The main endpoint for Twilio webhooks is /webhook/twilio. It expects POST requests from Twilio.

• Processing Logic:

  The application processes incoming messages and generates a response based on the provided context.

Troubleshooting

• Common Issues:

  • Ensure Ngrok is running and the URL is correctly configured in Twilio.
  • Check server logs for any errors or issues.
  • Verify that all environment variables are set correctly.
