We don't usually think much about Webhooks -- at least I don't. It's just web requests after all, right? In reality, there is a lot of complexity behind routing webhook requests through the internet. What if a webhook request gets lost? How do you know it was received in the first place? Can it be a security issue if a webhook gets handled twice? (Spoiler alert: yes)

Today I sit down with Tom from Svix to talk about what it takes to build an enterprise-ready webhook service. Of course it's written in Rust.
