Data access patterns for simple Stripe integrations

Summary

The article examines how applications should store and access product data in simple Stripe integrations as requirements for security, performance, and scalability evolve. It compares using Stripe’s built-in product fields with a separate database, while explaining that publishable API keys cannot retrieve product details and that secret or restricted keys must remain server-side. A web backend or serverless function can proxy requests securely, while CloudFront caching reduces repeated calls and latency but requires an appropriate refresh cadence. For richer metadata, inventory, variants, or custom attributes, the article describes combining DynamoDB with Lambda and Stripe, using Event Destinations or webhooks to synchronize changes and weighing that flexibility against database overhead.

Takeaways

1. 1

   Publishable API keys can collect payment information but cannot retrieve Stripe product details; secret and restricted keys should be handled on the server side.

2. 2

   CloudFront can reduce Lambda, API Gateway, and Stripe calls by serving cached data, but cache updates must balance response performance with data freshness.

3. 3

   A separate database supports variants, inventory, custom metadata, and efficient querying, but requires synchronization with Stripe through Event Destinations or webhooks.
