API Versioning Best Practices
Learn API versioning best practices. Compare URL versioning, header versioning, and query parameter strategies for REST and GraphQL APIs.
API versioning allows you to make breaking changes without disrupting existing clients. Common strategies: URL versioning (/v1/users, /v2/users), header versioning (Accept: application/vnd.api.v1+json), and query parameter versioning (?version=1). Best practice is URL versioning for public APIs and header versioning for internal APIs. Test different versions with our <a href="/api-checker">API checker</a>.
