  Configure & Secure API endpoints

  Declaratively configure an idempotent REST API that supports HTTP request-response interactions with a Kafka service. Then set up a Server Sent Events (SSE) endpoint to reliably stream the service’s snapshots and events across the web. Wrap everything up by securing your REST and SSE endpoints with JWT access tokens. Get Started ➔
