How APIs Handle Billions of Events with Event-Driven Architecture

In this episode of The API Podcast, Lucas and Luna explore how event-driven architecture powers real-time API communication at massive scale. They break down the difference between traditional request-response APIs and event-driven systems using webhooks and event streams. Lucas explains how companies like GitHub and Twilio use event-driven patterns to handle billions of events daily, with concrete examples like GitHub's push event webhooks and Twilio's status callbacks. They discuss the trade-offs: eventual consistency, debugging complexity, and the challenge of idempotency in event delivery. Luna brings up a real-world case of a startup that migrated from polling to webhooks and cut server costs by 70 percent. The episode also covers event sourcing, the outbox pattern, and how event-driven APIs enable microservices to communicate asynchronously.
