How to Version Public Web APIs Without Mixing Routes and Contracts

Path versions like /api/v1 and semantic API versions solve different problems. Keep routing, compatibility, and release notes separated; otherwise client migrations get messy fast.

[ KEY POINTS ]
  1. /v1/ is a routing boundary, not the same thing as semantic versioning. Treating both as one contract confuses breaking-change policy.
  2. major.minor.patch fits API contracts and changelogs better than URL structure. Clients need compatibility rules, not just a path label.
  3. Small public APIs should document what triggers a new route versus a contract version bump. That saves support time when SDKs or integrations depend on it.
