REST API Engineering Studio

KRW 510,000 · informational list price

Design versioned HTTP APIs with validation, pagination, and problem payloads that reviewers can follow.

You practice contract-first thinking with OpenAPI drafts, implement controllers that stay thin, and learn how to evolve endpoints without surprising clients. Case studies come from operational reporting APIs rather than toy CRUD demos.

What you build and study

  • OpenAPI-first iteration with review checkpoints
  • Pagination strategies and stable sorting keys
  • RFC7807-style problem details
  • Idempotency keys for mutating routes
  • Consumer-driven contract notes for partners
  • Mock servers for parallel frontend work
  • Load testing hooks with sensible baselines

Outcomes

  • Publish an API changelog alongside code
  • Defend design trade-offs in a mock design review
  • Instrument latency and error budgets on critical paths

Mentor

Spent a decade shipping public HTTP surfaces for logistics products.

Questions

Only comparisons in a single session. The course stays focused on REST patterns most Spring teams still maintain.

Recent reflections

  • “Problem detail homework was picky, but it changed how I write release notes for API tweaks.”
