-# FastAPI Application
+# Stripe Payment Integration Service
 
-This is a FastAPI application bootstrapped by BackendIM, the AI-powered backend generation platform.
+A FastAPI service for handling Stripe payments with complete payment processing capabilities.
+
+## Features
+
+- Create and manage Stripe payment intents
+- Process payments securely
+- Handle Stripe webhooks for payment status updates
+- Store payment records in SQLite database
+- RESTful API with automatic OpenAPI documentation
+- Health check endpoint
+
+## Environment Variables
+
+You need to set the following environment variables:
+
+```bash
+STRIPE_SECRET_KEY=sk_test_your_stripe_secret_key_here
+STRIPE_WEBHOOK_SECRET=whsec_your_webhook_secret_here
+```
+
+## Installation
+
+1. Install dependencies:
+```bash
+pip install -r requirements.txt
+```
+
+2. Run database migrations:
+```bash
+alembic upgrade head
+```
+
+3. Start the development server:
+```bash
+uvicorn main:app --reload --host 0.0.0.0 --port 8000
+```
+
+## API Endpoints
+
+### Base Endpoints
+- `GET /` - Service information
+- `GET /health` - Health check
+- `GET /docs` - Interactive API documentation
+- `GET /redoc` - Alternative API documentation
+
+### Payment Endpoints
+- `POST /api/v1/payments/create-payment-intent` - Create a new payment intent
+- `GET /api/v1/payments/payment-intent/{payment_intent_id}` - Get payment intent details
+- `GET /api/v1/payments/payment/{payment_intent_id}` - Get payment record from database
+- `POST /api/v1/payments/webhook` - Handle Stripe webhooks
+
+## Usage Example
+
+### Create a Payment Intent
+
+```bash
+curl -X POST "http://localhost:8000/api/v1/payments/create-payment-intent" \
+     -H "Content-Type: application/json" \
+     -d '{
+       "amount": 2000,
+       "currency": "usd",
+       "customer_email": "customer@example.com",
+       "customer_name": "John Doe",
+       "description": "Payment for services"
+     }'
+```
+
+### Response
+
+```json
+{
+  "client_secret": "pi_xxxxx_secret_xxxxx",
+  "payment_intent_id": "pi_xxxxx",
+  "amount": 2000,
+  "currency": "usd",
+  "status": "requires_payment_method"
+}
+```
+
+## Database Schema
+
+The service uses SQLite with the following tables:
+
+### Payments Table
+- `id` - Primary key
+- `stripe_payment_intent_id` - Stripe payment intent ID
+- `amount` - Payment amount
+- `currency` - Payment currency
+- `status` - Payment status
+- `customer_email` - Customer email
+- `customer_name` - Customer name
+- `description` - Payment description
+- `metadata` - Additional metadata (JSON)
+- `created_at` - Creation timestamp
+- `updated_at` - Last update timestamp
+- `is_webhook_processed` - Webhook processing status
+
+### Payment Methods Table
+- `id` - Primary key
+- `stripe_payment_method_id` - Stripe payment method ID
+- `customer_email` - Customer email
+- `type` - Payment method type
+- `card_brand` - Card brand (for card payments)
+- `card_last_four` - Last four digits of card
+- `is_default` - Default payment method flag
+- `created_at` - Creation timestamp
+
+## Development
+
+### Code Formatting
+The project uses Ruff for code formatting and linting:
+
+```bash
+ruff check .
+ruff format .
+```
+
+### Database Migrations
+To create a new migration:
+
+```bash
+alembic revision --autogenerate -m "Description of changes"
+```
+
+To apply migrations:
+
+```bash
+alembic upgrade head
+```
+
+## Webhook Configuration
+
+Configure your Stripe webhook endpoint URL in the Stripe Dashboard:
+- URL: `https://yourdomain.com/api/v1/payments/webhook`
+- Events: `payment_intent.succeeded`, `payment_intent.payment_failed`
+
+## Security Notes
+
+- Always use HTTPS in production
+- Store Stripe keys securely as environment variables
+- Verify webhook signatures for security
+- Never expose secret keys in client-side code
