Core Strategy
Start with explicit versioning policy, compatibility contract tests, and objective deprecation timelines. Avoid ad hoc breaking changes in shared endpoints.
Implementation Pattern
- Use semantic API versioning policy for major contract changes
- Introduce adapter layers for legacy payload support
- Maintain consumer-facing migration guides with examples
- Enforce contract checks in CI before release
Operational Recommendations
Track endpoint adoption and sunset legacy versions only after objective usage thresholds and communication milestones are met.
