Have you used header-based versioning?
💡 Model Answer
Header-based versioning places the API version in a custom HTTP header (e.g., X-API-Version: 2). Clients specify the desired version, and the server routes the request accordingly. This approach keeps URLs clean, allows multiple versions to coexist without URL changes, and enables version negotiation. It also simplifies caching and can be combined with content negotiation. However, it requires clients to set headers correctly and may complicate tooling that expects versioning in the path.
