API Deprecation and Sunset Strategy

This lesson adds advanced coverage to REST API Development based on the official documentation and practical production work.

Focus for this lesson: version retirement with headers, docs, and migration paths.

Learning Goals

  • Understand the core idea and when to use it.
  • Apply it in a real project without breaking security or performance.
  • Connect it to tests, documentation, and monitoring when needed.

Practical Example

Sunset: Wed, 11 Nov 2026 23:59:59 GMT
Documentation reference: HTTP Sunset header and API lifecycle docs.

Professional Implementation Steps

  • Review boundaries and responsibilities before writing code.
  • Build a small example and then apply it to a real feature.
  • Add a test or smoke check that proves the behavior.
  • Document the impact on maintenance and deployment.

Hands-on Practice

Apply this topic to an existing page, API, or component, then review the result for maintainability, security, performance, and user experience.

Production addition: do not judge success only by running the example. Judge it by how clear, testable, and maintainable the decision is.
Avoid copying documentation patterns blindly. Tie every option to a clear project reason.

Summary

Add this topic to your toolbox as an engineering decision that can be explained, tested, and reviewed.
