Versioning Strategies

Managing API evolution

APIs evolve. Versioning prevents breaking clients:

URL path versioning:

/api/v1/users
/api/v2/users

Most common. Clear and explicit.

Header versioning:

Accept: application/vnd.api+json;version=2

Cleaner URLs but less discoverable.

Query parameter:

/api/users?version=2

Easy to test but pollutes parameters.

Best practices:

Support old versions for deprecation period
Document breaking changes clearly
Use semantic versioning principles
