The Svix Implementation Guide provides a step-by-step overview of how to launch webhooks, including deciding which events to send, figuring out where to hook into Svix, embedding the consumer application portal, configuring the environment and creating event types, testing and validation, and launching with customers. The guide emphasizes the importance of being thoughtful about webhook decisions, starting small, and using tools like automated testing and a pre-built consumer app portal to make the integration process smoother. The exact time it takes to complete the integration varies depending on the company size and complexity, but two weeks is often a reasonable estimate.
