I've been working on improving developer experience around event-driven integrations lately, and webhooks continue to be one of those deceptively "simple" tools that actually require quite a bit of infrastructure to handle properly at scale—retries, signature validation, queuing, DLQs, observability, etc.

I recently published a technical post that goes deep into what webhooks are, how they actually work under the hood, and why they matter in modern architectures: https://vartiq.com/blog/what-is-webhook-how-it-works-and-why...

Would love to hear how others are handling webhooks in production:

1. How are you queuing/processing them? 2. Do you use a third-party tool? 3. What kind of failure handling/retries do you implement?

Curious what the broader HN community thinks about the evolution of webhooks and whether we're due for better primitives around this.
