How to Design Idempotent Webhook Delivery That Developers Trust
from The Developer Tools Podcast with Fexingo: APIs, Infrastructure, and Software for Engineers Hosted by Fexingo
In this episode, Lucas and Luna dig into the design decisions behind webhook delivery that developers can rely on. They explore the problem of duplicate events, the role of idempotency keys in webhook payloads, and how delivery receipts change the trust equation. Using the example of a payment provider that processes millions of events daily, they show why a simple 'at-least-once' guarantee isn't enough and how to build a system that lets clients safely deduplicate. They also touch on the trade-offs between exactly-once and at-least-once semantics, and why observability is the secret weapon for webhook consumers. If you've ever built or consumed webhooks, this episode gives you a framework for making them less fragile and more debuggable. A must-listen for platform engineers and API designers who want to reduce integration pain for their users. #WebhookDelivery #Idempotency #API Design #DeveloperExperience #PlatformEngineering #EventDriven #Reliability #Observability #PaymentAPIs #DistributedSystems #BackendDev #TechPodcast #BusinessAndTech #FexingoBusiness #BusinessPodcast #DevTools #EngineeringCulture #API Reliability Keep every episode free: buymeacoffee.com/fexingo
