Webhook Architecture Design

Tom Hacohen, CEO of Svix, sat down with Ken Ruf, Head of Growth at Svix, to discuss webhook architecture and best practices for sending webhooks at scale. They talked about scalability, security, developer experience, customer experience, and the importance of monitoring and visibility in a webhook system. Tom emphasized the need for retries, security measures such as signing requests and using HMAC, fan out to multiple services, filtering by event types, and providing visibility into delivery status. He also highlighted the importance of defining requirements upfront and considering factors like rate limiting to ensure smooth operation at scale.
