Webhooks are everywhere in modern systems—but they’re often misunderstood.
In this video, we break down how webhooks actually work, using clear visuals and real-world examples to show how events flow between systems and what really happens behind the scenes.
We’ll compare polling vs webhooks, walk through webhook components, explain delivery guarantees and reliability issues, and cover the most important best practices—like security and idempotency—that developers often miss.

✅ What webhooks are (and what they are not)

✅ How polling differs from event-driven communication

✅ The key components of a webhook system

✅ Delivery guarantees, retries, ordering, and duplicates

✅ Security, signatures, and idempotency

✅ When webhooks are the right tool—and when they’re not

Webhooks are push-based notifications that eliminate the need for constant polling by allowing servers to send real-time event data to your application when specific actions occur. Unlike REST APIs where you repeatedly request data, webhooks require you to provide a public URL endpoint that receives HTTP POST requests containing event payloads. Common use cases include payment processing, video encoding completion, and CI/CD pipeline triggers. Key implementation considerations include verifying request signatures for security, handling duplicate events through idempotency, and managing out-of-order delivery using timestamps.
