api-versioning-strategy

The best way to version a REST API safely is selecting a strategy like URL path, custom header, or media-type versioning. This ensures parallel old and new versions run during migration, preventing breaks while allowing progress.

To implement a deprecation policy for an evolving GraphQL API, apply an evolutionary versioning approach using sunset windows and deprecation headers. This provides migration guidance and minimizes client disruption during schema changes.

Yes, this API versioning strategy supports gRPC and event streams. It applies tailored versioning and deprecation policies across REST, GraphQL, gRPC, and event streams to fit various API styles and consumer bases.

To enforce a phased rollout with parallel support, use a phase-based roadmap that maintains both old and new API versions during migration. Combine this with in-band and out-of-band communications alongside migration documents.

Use media-type versioning instead of URL path versioning when you need evolutionary versioning without changing endpoint paths. The strategy selection depends on your specific API style, intended consumers, and change profile to generate the optimal plan.
