  title: Svix Register Event Type and Send Example
  summary: Create an event type, subscribe an endpoint to it, and send the event type's example message.
  description: >-
    Event types are the schema-bearing catalog entries that drive Svix
    delivery. This workflow registers a new event type, creates an endpoint
    that filters on it for an existing application, and then asks Svix to send
    the event type's built-in example payload to that endpoint so the
    integration can be verified end to end. Every step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.
