Stripe Integration Kit
Part of the Payment Stack by CodeVault
A complete local simulation of Stripe payment workflows: checkout sessions, payment intents, customer management, and webhook signature verification. Understand every pattern before touching the real API.
Features
- Full checkout session lifecycle (create → complete → webhook)
- Payment intent state machine (requires_method → processing → succeeded)
- Customer CRUD with metadata support
- Webhook signature generation and HMAC-SHA256 verification
- Idempotency key handling to prevent duplicate charges
- JSON file-based persistence (swap for your real database)
- Supports 16 currencies with minimum amount validation
- Full demo mode showing the end-to-end flow
- Python stdlib only — zero dependencies
Quick Start
# Run the full demo (creates customer, payment intent, checkout session)
python src/stripe_integration_kit.py --action demo
# Create a customer
python src/stripe_integration_kit.py --action create-customer --email user@example.com --name "Jane Dev"
# Create a $49.99 payment intent
python src/stripe_integration_kit.py --action create-intent --amount 4999 --currency usd
# Confirm a payment
python src/stripe_integration_kit.py --action confirm-intent --intent-id pi_abc123
# Create a checkout session
python src/stripe_integration_kit.py --action create-checkout --customer cus_001 --amount 2999
# List all customers
python src/stripe_integration_kit.py --action list-customers

Stripe Integration Kit — Payment Stack by DataNest
A complete local simulation of Stripe payment workflows: checkout sessions,
payment intents, customer management, webhook handling, and customer portal
sessions. Demonstrates all the logic you'd need to integrate Stripe into
a real application — without requiring an actual Stripe API key.
Why this exists:
Integrating Stripe is conceptually simple but operationally complex. You
need to handle idempotency keys, webhook signature verification, customer
lifecycle events, payment intent state machines, and error recovery. This
kit implements the full workflow locally so you can understand the patterns,
test your integration logic, and build confidence before touching the real
API. Swap the mock HTTP layer for `requests` and you're production-ready.
Usage:
python stripe_integration_kit.py --action create-checkout --customer cus_001
python stripe_integration_kit.py --action create-intent --amount 4999 --currency usd
python stripe_integration_kit.py --action verify-webhook --payload-file event.json
python stripe_integration_kit.py --action list-customers --data-dir ./stripe_data
