Stripe Integration Architecture
The overall design of how your application communicates with Stripe's APIs for payment processing, customer management, and subscription handling.
Description
Stripe integration architecture defines how your backend services interact with Stripe's suite of APIs to handle payments, subscriptions, invoicing, and customer data. A well-designed architecture separates Stripe-specific logic into a dedicated service layer, isolating API calls, webhook handlers, and data mapping from your core business logic. This abstraction makes it feasible to swap payment providers or support multiple providers without rewriting your entire payment flow.
The architecture typically involves a server-side SDK (stripe-node, stripe-python, etc.) for creating and managing Stripe objects, a webhook ingestion endpoint for processing asynchronous events, and a thin client-side layer using Stripe.js or Elements for secure card collection. The server maintains a mapping between your internal user/account models and Stripe Customer objects, storing the Stripe customer ID alongside your user record. API keys are split into publishable keys (client-side, restricted scope) and secret keys (server-side only), with separate keys for test and live modes.
Production architectures should account for Stripe API versioning by pinning to a specific API version, rate limiting considerations (Stripe enforces 100 requests/second in live mode), and graceful degradation when Stripe is experiencing downtime. Idempotency keys should be used on all mutating requests to prevent duplicate operations during retries.
Prompt Snippet
Structure the Stripe integration behind a PaymentService abstraction layer that encapsulates all stripe-node SDK calls, mapping internal domain models to Stripe API objects (Customer, PaymentIntent, Subscription, Invoice). Store the stripe_customer_id on your users table and lazily create Stripe Customer objects on first payment interaction. Pin the Stripe API version in your SDK initialization and use idempotency keys on all POST requests to handle network retries safely. Separate webhook ingestion into its own route with raw body parsing to support signature verification.
