#rest#api#versioning

Answer

  1. URI versioning: Include the version in the URL (e.g., /api/v1/resource). Easy to use but makes URLs longer.
  2. Query parameter versioning: Use a query string (e.g., /api/resource?v=1). Simple, but can be overlooked by clients.
  3. Header versioning: Send version info in request headers (e.g., Accept: application/vnd.example.v1+json). Keeps URLs clean but may require client complexity.
  4. Semantic versioning: Use a combination of the above approaches while adhering to semantic versioning principles to signal breaking changes clearly.
