What is API Versioning?

API Versioning is the practice of managing changes to an API specification across multiple released iterations without breaking existing client integrations.

Detailed Explanation

Common strategies include URL path versioning (/v1/users), custom header versioning (X-API-Version: 1), and Accept header content negotiation.

Common Mistakes to Avoid

  • Changing field types in minor releases
  • Deprecating endpoints without deprecation headers

Verify Version Prefixes with APIForge

Paste any OpenAPI specification URL or YAML file into APIForge for instant 0-100 quality scoring, schema linting, and zero-CORS proxy testing.
