How APIs Use Webhooks for Real-Time Event-Driven Architecture

Episode 27 of The API Podcast digs into webhooks — the unsung backbone of real-time event-driven architecture. Lucas walks through how Twilio and GitHub use webhooks to push data instead of forcing developers to poll, saving millions in compute costs and cutting latency from seconds to milliseconds. Luna questions the reliability trade-offs: what happens when your webhook endpoint is down? They explore retry policies, payload signing for security, and a concrete case where a startup replaced 80 percent of their API polling with a single webhook subscription. If you design or consume APIs, this episode gives you a practical mental model for when to use webhooks versus polling versus Server-Sent Events — and the one number that convinced a team to switch. #Webhooks #EventDrivenArchitecture #RealTimeAPIs #Twilio #GitHub #ServerSentEvents #Polling #APIDesign #PayloadSigning #WebhookSecurity #EventDrivenDesign #TechPodcast #SoftwareEngineering #DeveloperTools #BackendDevelopment #APIEconomy #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
