Webhooks and beyond

Webhooks have become the go-to mechanism for delivering platform events. While transformative, they suffer from well-known limitations.

Best practices today dictate validating and queuing webhooks via a message bus upon receipt. This raises a fundamental question: Why rely on the inefficiency of a public HTTP endpoint at all? Why not deliver events directly to a secure, efficient destination?

The future of event delivery lies in interoperable, secure, and efficient Event Destinations. By embracing this pattern, we can build a developer experience that drives progress and simplifies event-driven architectures for everyone.

“I've been working with (and against) webhooks for years, both as a consumer and an producer, always wishing that we as an industry could come up with something better. In my opinion, Event Destinations are exactly that.”
