为什么值得看
HN热门讨论揭示了Webhooks在实际工程中的系统性难题：可靠性差、调试困难、版本兼容性混乱。对构建SaaS集成或API平台的工程师有直接参考价值，能避免踩过前人已踩的坑。
编辑判断
HN评论区里一线工程师的实战经验比原文更有价值。高频痛点集中在三个场景：消费者端没有幂等设计导致重复处理、提供者端随意变更payload结构却不发版本号、以及没有标准化重试策略让下游被突发流量打崩。
如果你正在设计事件通知系统，建议直接参考Stripe和GitHub的Webhooks实现作为baseline，它们的签名验证、事件ID去重、以及exponential backoff+jitte的重试机制已经是行业事实标准。另一个被低估的方案是考虑用Supabase Realtime或Ably这类托管服务替代自建，除非你的事件量级真的到了需要自研调度层的程度。

Dude is not wrong ... but good luck convincing the Internet to switch to a sane system, when everyone already thinks web hooks are a "solved problem".
The end here reminds me of "The Log: Real-time data's unifying abstraction" [0], which has unfortunately had a bit of link-rot since 2013. One complication in this approach involves access-windows: What if my system is only supposed to be seeing stuff that happened during two separate weeks in the y
Webhooks are a painful problem. To clarify, Stripe's events API definitely ships a cursor and polling it has been the method preferred by large consumers for a long time.
