6. Testing

Perform end-to-end testing to ensure:

Call flow works seamlessly from customer initiation to AI responses.

Payment authorization and capture are accurate based on call duration.

Receipts are generated correctly and sent to customers.

System handles edge cases like call disconnections, exceeding authorized amounts, and payment failures.

Use test environments provided by Stripe, Twilio, and OpenAI to simulate real-world scenarios.

Step-by-Step Implementation with Coding Examples

Step 1: Set Up Accounts and Obtain API Keys

Stripe:

Create an account at Stripe.

Complete business verification to activate payment processing.

Obtain your API Secret Key and configure a webhook endpoint for payment updates.

Twilio:

Sign up at Twilio.

Purchase a phone number for handling incoming calls.

Enable Programmable Voice and configure webhooks to route calls to your backend.

OpenAI:

Sign up at OpenAI.

Obtain your API key and familiarize yourself with the ChatGPT API documentation.

Hosting:

Set up a cloud hosting environment using Heroku, AWS, or Google Cloud for backend deployment.

Step 2: Develop the Backend System

Initialize the Project

Create a project directory and initialize it with the required libraries.

pip install flask stripe twilio openai

Set up environment variables for secure storage of API keys.

export STRIPE_API_KEY='your_stripe_api_key'

export TWILIO_ACCOUNT_SID='your_twilio_account_sid'

export TWILIO_AUTH_TOKEN='your_twilio_auth_token'

export OPENAI_API_KEY='your_openai_api_key'

Code Example: Payment Authorization and Capture

Authorize Payment at Call Start:

import stripe

stripe.api_key = "your_stripe_secret_key"

def authorize_payment():

payment_intent = [login to view URL](

amount=2500, # Amount in cents

currency="usd",

payment_method="pm_card_visa", # Replace with actual payment method ID

capture_method="manual",

)

return [login to view URL]

Capture Payment at Call End:

def capture_payment(payment_intent_id, final_amount):

[login to view URL](

payment_intent_id,

amount=final_amount,

)

[login to view URL](payment_intent_id)

Code Example: Twilio Integration

Handle Incoming Calls:

from flask import Flask, request

from twilio.twiml.voice_response import VoiceResponse

app = Flask(__name__)

@[login to view URL]("/incoming_call", methods=["POST"])

def handle_call():

response = VoiceResponse()

[login to view URL]("Welcome to the AI-powered phone service. Please hold while we connect you.")

# Forward call logic here

return str(response)

if __name__ == "__main__":

[login to view URL](port=5000)

Code Example: OpenAI Integration

ChatGPT Response Generation:

import openai

openai.api_key = "your_openai_api_key"

def get_chatgpt_response(transcription):

response = [login to view URL](

model="gpt-4",

messages=[

{"role": "system", "content": "You are a helpful conversational assistant."},

{"role": "user", "content": transcription},

],

)

return [login to view URL][0].message["content"]

Step 3: Create the Web Interface

Frontend Tasks:

Use HTML to create a simple form for customer registration.

Add JavaScript to handle form submissions and API requests to the backend.

<form id="register-form">

<input type="text" name="name" placeholder="Name" required />

<input type="email" name="email" placeholder="Email" required />

<input type="text" name="card_number" placeholder="Card Number" required />

<button type="submit">Register</button>

</form>

[login to view URL]('register-form').addEventListener('submit', async (e) => {

[login to view URL]();

const formData = new FormData([login to view URL]);

const response = await fetch('/api/register', {

method: 'POST',

body: formData,

});

const result = await [login to view URL]();

alert([login to view URL]);

});

Step 4: Testing and Debugging
