Payment Gateway Integration
Table of Contents
Overview
Build secure payment processing systems with major payment providers (Stripe, PayPal, Square), handling transactions, subscriptions, webhooks, PCI compliance, and error scenarios across different backend frameworks.
When to Use
- Processing customer payments
- Implementing subscription billing
- Building e-commerce platforms
- Handling refunds and disputes
- Managing recurring charges
- Integrating payment webhooks
Quick Start
Minimal working example:
# config.py
import os
class StripeConfig:
STRIPE_SECRET_KEY = os.getenv('STRIPE_SECRET_KEY')
STRIPE_PUBLISHABLE_KEY = os.getenv('STRIPE_PUBLISHABLE_KEY')
STRIPE_WEBHOOK_SECRET = os.getenv('STRIPE_WEBHOOK_SECRET')
# stripe_service.py
import stripe
from datetime import datetime, timedelta
import logging
logger = logging.getLogger(__name__)
stripe.api_key = os.getenv('STRIPE_SECRET_KEY')
class StripePaymentService:
@staticmethod
def create_payment_intent(amount, currency='usd', description=None, metadata=None):
"""Create a payment intent"""
try:
intent = stripe.PaymentIntent.create(
amount=int(amount * 100), # Convert to cents
currency=currency,
// ... (see reference guides for full implementation)

- Implement retry logic
❌ DON'T
- Handle raw card data
- Store sensitive payment information
- Log sensitive details
- Trust client-side validation only
- Ignore webhook events
- Hardcode API keys
- Use test keys in production
- Skip SSL/TLS verification
- Forget to validate amounts
- Store payment tokens without encryption

Popular backend & apis skills
find-skills
vercel-labs/skills
Helps users discover and install agent skills when they ask questions like "how do I do X", "find a skill for X", "is there a skill that can...", or express interest in extending capabilities.

google/agents-cli
This skill should be used when the user wants to "write agent code", "build an agent with ADK", "add a tool", "create a callback", "define an agent", "use state management" — in a project that needs ADK (Agent Development Kit) API patterns and code examples. It provides a quick reference for agent types, tool definitions, orchestration patterns, callbacks, state management, the graph Workflow API, and reference recipes to study. Do NOT use for scaffolding (use google-agents-cli-scaffold) or deployment (use google-agents-cli-deploy).
embedded-captions
heygen-com/hyperframes
Add captions or subtitles to an existing single-subject talking-head video without editing the footage. Use for plain verbatim captions, cinematic captions embedded behind the subject, VFX captions, “炸/特效/酷炫字幕,” or a named identity from the 35-style catalog. Route by visual identity, not by backend engine. The quiet anchor rail is the default; embed every word only when the user explicitly wants a fully cinematic treatment. The workflow runs locally end to end, including transcription and subject matting; split multi-shot footage before applying it.
