Quick Answer
API versioning in production: run v1 and v2 simultaneously. Track which clients use each version via analytics. Set a deprecation date for v1, communicate to all clients, add Deprecation and Sunset headers to v1 responses. Monitor v1 traffic - only retire when traffic approaches zero. Never break existing clients without warning. Version at the URL level (/api/v1) for maximum visibility.
Answer
Support multiple API versions safely. Methods: URL versioning, headers, query params. Enables backward compatibility and gradual migration.
