Stripe Integration: Payments, Subscriptions, Webhooks
Payment gateway is a critical conversion point. An error at checkout means losing a customer. Stripe solves this: minimal friction for users, automatic 3D Secure handling, support for Apple Pay and Google Pay. Stripe supports over 135 currencies and dozens of payment methods, including SEPA, iDEAL, and Klarna. With a unified API, adapting to local methods takes half the time compared to competitors. We have been using Stripe in commercial projects for over five years, integrated it into 50+ projects, and guarantee stable integration with any stack—from Laravel to React.
A common pain point is incorrect webhook handling, causing orders not to be marked as paid. We break down how to avoid this and offer a turnkey solution. Reducing payment declines by 40% is a real result after configuring Stripe Radar and fraud monitoring rules.
Why Stripe is Better Than Alternatives
Stripe outperforms PayPal and Adyen in UI customization flexibility and implementation speed. Unlike PayPal, Stripe gives full control over the checkout flow via Elements and Payment Intents. Adapting local methods (SEPA, iDEAL) is twice as fast as competitors thanks to a unified API. The single Payment Intents interface simplifies PSD2 and SCA compliance.
How Stripe Protects Against Fraud
Stripe uses machine learning to analyze transactions in real time. Radar automatically blocks suspicious operations and reduces chargebacks. You can create custom rules: for example, reject orders from anonymous IPs or require 3D Secure for amounts over $500. In our projects, we configure Radar together with the charge.dispute.created webhook for prompt dispute response.
Why Choose Custom Integration via Payment Intents
Checkout Session lets you launch in a day but lacks flexibility for subscriptions and complex discount logic. Payment Intents gives full UI control via Stripe Elements: you can embed the payment form into your design, save cards for repeat purchases, and manage multi-currency. In the long run, custom integration saves up to 25% on fees by optimizing payment routing.
How We Integrate Stripe: Workflow
- Analysis — we study your business scenario: one-time payments, subscriptions, multi-currency, UI requirements.
- Design — we choose the integration method: Payment Intents (custom UI with Stripe Elements) or Checkout Session (ready-made page).
-
Implementation — we write code on Laravel (PHP 8.3+) and React/Next.js with TypeScript. We use the official SDKs
stripe/stripe-phpand@stripe/react-stripe-js. - Testing — we run all cases: success, failure, 3D Secure, refund, limit exceeded, cancellation.
- Deployment — we set up webhooks with signature verification, monitoring, and error logging.
Timeline: 3 to 7 business days. We'll assess your project in one day—get in touch. Receive a consultation on Stripe integration—we'll evaluate your project in one day.
What's Included in the Integration
- API documentation with request examples.
- Webhook handler with signature verification.
- Test environment with Stripe test cards.
- Team training (one hour).
- Two weeks of support after launch.
Comparison of Integration Methods
| Criteria | Payment Intents | Checkout Session |
|---|---|---|
| UI customization | Full (Stripe Elements) | Limited (ready-made page) |
| Subscriptions | Supported (via Product/Price) | Only via Customer Portal |
| 3D Secure | Automatic | Automatic |
| Implementation time | 3-5 days | 1-2 days |
| Recommended cost | Higher (custom development) | Lower (ready-made page) |
Typical Errors and Their Solutions
| Problem | Solution |
|---|---|
| Incorrect webhook signature | Verify the Stripe-Signature header using the library |
| Duplicate payments | Use idempotency with the idempotency_key parameter |
| Session loss | Save client_secret on the client and restore via retrieve |
How to Set Up Webhook Handling
For local development, use Stripe CLI: stripe listen --forward-to localhost:8000/webhook/stripe. On the server, specify the URL in the Dashboard. The handler must return 200 OK and verify the signature. Example code:
public function handleWebhook(Request $request): Response { $payload = $request->getContent(); $sigHeader = $request->header('Stripe-Signature'); try { $event = \Stripe\Webhook::constructEvent( $payload, $sigHeader, config('services.stripe.webhook_secret') ); } catch (\Stripe\Exception\SignatureVerificationException $e) { return response('Invalid signature', 400); } match ($event->type) { 'payment_intent.succeeded' => $this->handleSuccess($event->data->object), 'payment_intent.payment_failed' => $this->handleFailed($event->data->object), default => null, }; return response('OK', 200); } private function handleSuccess(\Stripe\PaymentIntent $intent): void { $orderId = $intent->metadata->order_id; Order::where('id', $orderId)->update([ 'status' => 'paid', 'transaction_id' => $intent->id, ]); } What to Do on Payment Errors
Stripe notifies via the payment_intent.payment_failed event. In the handler, log the reason (decline_code) and notify the customer. To reduce declines, enable automatic card updating and configure fraud monitoring rules.
