Stripe is a modern payment processing platform providing comprehensive APIs and tools for accepting payments, managing subscriptions, and building payment infrastructure. Stripe's developer-friendly approach, extensive documentation, and powerful capabilities have made it the preferred choice for many online businesses and platforms. Proper Stripe integration enables secure payment processing, subscription billing, and advanced revenue optimisation.
Stripe Fundamentals
Stripe provides several core capabilities:
Payment processing - Accepting one-time payments through credit cards, digital wallets, and alternative payment methods.
Subscription billing - Managing recurring subscription charges, including automated renewal, prorated adjustments, and dunning management.
Connect - Creating marketplace platforms where multiple sellers accept payments and retain portions of transaction value.
Billing - Comprehensive subscription and invoicing management.
Fraud detection - Advanced machine learning algorithms detecting and preventing fraudulent transactions.
Stripe Products and Services
Stripe offers specialised products:
Stripe Payments - Core payment processing for one-time and recurring charges.
Stripe Billing - Subscription management including automated invoicing and dunning.
Stripe Connect - Marketplace infrastructure enabling sellers to accept payments.
Stripe Radar - Fraud prevention leveraging machine learning to detect suspicious transactions.

Integration Approaches
Stripe supports multiple integration approaches:
Stripe.js - JavaScript library enabling secure payment form building on your website.
Payment intents - Modern API for handling multi-step payments, supporting payment methods beyond cards.
Webhooks - Event notifications when payment status changes, enabling automated responses.
Server-side integration - Direct API calls for backend payment processing.
Mobile SDKs - iOS and Android libraries for payment processing in mobile apps.
Secure Payment Implementation
Secure Stripe integration requires careful practices:
API key management - Storing publishable and secret API keys securely. Secret keys should never be exposed in client-side code.
HTTPS everywhere - All communication must use HTTPS encryption.
Tokenisation - Stripe tokens represent payment information without storing sensitive data directly.
Webhook verification - Verifying that webhooks genuinely come from Stripe using signed headers.
PCI compliance - Using Stripe's secure methods avoids handling raw payment data and PCI compliance complexity.
Payment Methods
Stripe supports diverse payment methods:
Cards - Credit cards, debit cards, and prepaid cards from major networks.
Wallets - Apple Pay, Google Pay, and Microsoft Pay for convenient mobile payments.
Bank transfers - ACH transfers in the US, SEPA transfers in Europe.
Local methods - Alipay, WeChat Pay, iDEAL, and many region-specific payment methods.
BNPL - Buy-now-pay-later options like Afterpay and Klarna.
Supporting multiple methods increases conversion by letting customers pay their preferred way.
Subscription Billing
Stripe Billing simplifies subscription management:
Recurring charges - Automatically charging customers on a schedule.
Metered billing - Billing for variable usage (e.g., API calls, storage) rather than fixed plans.
Proration - Handling mid-cycle changes (upgrades, downgrades) with prorated billing.
Dunning - Managing failed payment retry logic, recovering failed charges.
Invoicing - Generating professional invoices and sending to customers.
Seat-based billing - Scaling prices with number of users (seats) for SaaS applications.
Stripe Connect for Marketplaces
Connect enables building marketplace platforms:
Express accounts - Simplifying seller onboarding through Stripe-hosted account creation.
Payout splits - Automatically distributing transaction proceeds to sellers.
Seller payouts - Directly depositing funds to seller bank accounts.
Compliance - Connect handles regulatory requirements for marketplace payment flows.
Two-sided marketplaces like those PixelForce builds frequently leverage Connect for payment handling.
Handling Payment Failures
Stripe provides sophisticated failure handling:
Automatic retries - Stripe automatically retries failed charges according to configurable logic.
Webhooks notification - Your system receives notifications of failed charges, enabling appropriate action.
Dunning management - Sophistiated retry strategies recover failed payments rather than simply giving up.
Customer communication - Integrating with communication systems to notify customers of failures.
Monitoring and Analytics
Stripe provides visibility into payment operations:
Dashboard - Real-time overview of payments, subscriptions, and revenue.
Reporting - Detailed reports on transaction patterns, refunds, and disputes.
Radar rules - Creating custom rules triggering on suspicious patterns.
Searchable data - Querying payment history to understand customer transactions.
Security and Compliance
Stripe handles security and compliance:
PCI compliance - Stripe is PCI-compliant, reducing your own compliance burden.
Encryption - All data is encrypted in transit and at rest.
3D Secure - Additional authentication for high-risk transactions.
Regulatory compliance - Stripe manages complex regulatory requirements across jurisdictions.
Testing Stripe Integration
Thorough testing is essential:
Test mode - Stripe provides test environments enabling safe testing without real transactions.
Test cards - Using specific test card numbers to simulate various scenarios (successful charges, insufficient funds, etc.).
Webhook testing - Using Stripe's webhook testing tools to verify integration.
Error scenarios - Testing various failure and error conditions.
