API Documentation with OpenAPI / Swagger

A Kafka-backed REST API is still a REST API — clients need to discover and try it without reading your source code.

Learning objectives

  • Beginner: Explain why a Kafka-backed service still needs OpenAPI/Swagger documentation like any other REST API.
  • Intermediate: Add Swagger annotations to a producer's REST endpoints so its contract is discoverable without reading the source.
  • Advanced: Keep generated API docs accurate as the producer's DTOs evolve, without manually maintaining a separate spec file.
