How Stripe Built an API That Handles Millions of Requests Per Second

In this episode of The API Podcast, Lucas and Luna dive into the architectural decisions behind Stripe's API infrastructure, which processes millions of requests per second with remarkable consistency. They explore how Stripe uses idempotency keys to prevent duplicate charges, the trade-offs between synchronous and asynchronous payment processing, and why their API design philosophy centers on developer experience and reliability. Lucas explains the importance of idempotency in distributed systems, using real-world examples of network retries and payment failures. Luna questions whether Stripe's approach could be over-engineered for smaller teams, and they discuss how smaller startups can adopt similar principles without the complexity. The episode also touches on Stripe's use of eventual consistency and how they handle race conditions in financial transactions. If you've ever wondered how the world's most developer-friendly payment API stays rock-solid under massive load, this episode offers a practical breakdown of the key patterns. #StripeAPI #IdempotencyKeys #PaymentProcessing #APIDesign #DistributedSystems #DeveloperExperience #APIInfrastructure #MillionsOfRequests #EventualConsistency #RaceConditions #NetworkRetries #SynchronousVsAsynchronous #APIReliability #TechPodcast #Technology #FexingoBusiness #BusinessPodcast #API Keep every episode free: buymeacoffee.com/fexingo
