Best for

▸Designing backward-compatible API versioning strategies for breaking changes
▸Creating deprecation timelines and communication plans for API retirement
▸Implementing sunset headers and migration guides for version transitions
▸Establishing API governance policies for contract testing and change management
▸Planning API evolution paths while maintaining consumer SLA commitments

What you'll get

●Compatibility matrix categorizing changes as non-breaking, behavioral, or breaking with specific versioning recommendations
●Deprecation protocol with RFC-compliant headers, timeline milestones, and consumer notification templates
●Contract testing implementation guide with tool recommendations and automated compatibility checks

Not designed for ↓

×Writing actual API code or implementation details
×Designing specific API endpoints or data schemas
×Database migration or infrastructure deployment strategies
×General software architecture without API-specific lifecycle concerns

Expects

Current API version status, consumer landscape details, planned changes with compatibility impact assessment, and existing versioning approach.

Returns

Structured lifecycle management plan with versioning strategy, deprecation timeline, communication templates, and governance compliance framework.
