api-design-and-evolution

Design API contracts by prioritizing consumer jobs and domain semantics over implementation details to prevent breaking changes. This approach ensures durable, maintainable interfaces by making assumptions explicit and documenting failure modes.

Plan API deprecations and migrations using evolution frameworks that assess breaking changes and provide clear evidence for compatibility. This ensures durable consumer-focused contracts while managing transitions smoothly across REST, GraphQL, or event interfaces.

Yes, this approach works for REST, GraphQL, RPC, events, webhooks, and streaming interfaces. It applies contract-first design and compatibility assessments across the full lifecycle of multiple protocols to satisfy consumer requirements.

Document explicit failure modes by creating API briefs and contracts that prioritize consumer jobs and domain semantics. This contract-first approach ensures robust, maintainable interfaces by satisfying requirements for clear compatibility assessments and durable documentation.

You need contract-first API design when building consumer-facing interfaces that require robust integration and durable documentation. It prevents unwritten assumptions and breaking changes by guiding the creation of contracts focused on consumer jobs and domain semantics.

Yes, you can use this method to design an API contract for creating and listing invoices including retry and migration behavior. It guides the creation of durable, consumer-focused contracts that explicitly define failure modes and compatibility.
