Stripe integration that handles every edge case.
Payment integration is the highest-stakes code in most applications. A bug in the checkout flow costs real money. Getting Stripe integration right — payment intents, webhooks, error handling, idempotency — requires focused expertise.
Need Stripe integration built — one-time payments, subscriptions, or payment flow with proper error handling
Stripe integration has more surface area than it appears:
Payment Intents vs Checkout Sessions: Stripe Checkout (hosted page): easiest, limited customization. Payment Intents API: custom UI via Stripe Elements, full design control. For most SaaS: Stripe Checkout for subscriptions, Payment Elements for custom checkout UI.
Idempotency keys on every charge:
const paymentIntent = await stripe.paymentIntents.create({
amount: 2000,
currency: 'usd',
idempotencyKey: `payment_${orderId}` // Prevents duplicate charges on retry
});
Webhook handling for payment confirmation:
Never fulfill orders based on a successful client-side response. Fulfill based on payment_intent.succeeded webhook. Client-side success can be faked; webhook can't.
Failed payment handling:
Payment failures need to be surfaced to the user with actionable messages. Stripe's error codes map to specific messages: card_declined → "Your card was declined", insufficient_funds → "Insufficient funds".
Test coverage: Stripe provides test card numbers for every failure scenario. Testing the happy path isn't enough — test card declined, insufficient funds, 3DS authentication required.
