Read the full story Arnaud Frammery Software Engineer, API Connect Squad At my previous company (WorkOS) we had to build a lot of infrastructure internally to support webhooks.

You can think of them as a reverse-API or asynchronous API notifications. An API call is how a server can make requests from another service, and webhooks are how that service would asynchronously notify the server of events. What is webhooks as a service? Webhooks as a service refers to Svix's software as a service (SaaS) webhook platform. We've built a user interface for managing your users' webhook subscriptions as well as an API that simplifies the process of implementing webhook best practices at scale. What is a webhook service? A webhook service is similar to 'webhooks as a service' above, but also encompasses scenarios where the service is hosted by the service directly, rather than using the Svix WaaS offering. For example, a self-hosted instance of the Svix open source webhooks server would be considered a webhooks service. Are Svix webhooks secure? Yes! Our webhook service was designed for security from the ground up. We follow industry best practices, encrypt all data both in transit and at rest, and are compliant with SOC 2 Type II, GDPR, CCPA and more. Can Svix handle our scale? We process billions of messages for our customers, and we power top companies like Brex, Benchling, and Drata. We can most likely handle your scale, but please reach out if you have any specific questions or requirements. What are the challenges with building webhooks? Webhooks are a pain. Developers need to worry about deliverability, retries, monitoring, security, and much more. All of which are different for webhooks compared to the…
