API Versioning

API versioning strategies with moclojer - URL versioning, header versioning, and managing multiple API versions simultaneously for backward compatibility.

Implement API versioning in moclojer to support multiple API versions.

🎯 Versioning Strategies

1. URL Versioning

# v1 endpoints
- endpoint:
    method: GET
    path: /api/v1/users
    response:
      status: 200
      body: >
        {"users": [{"id": 1, "name": "Alice"}], "version": "1.0"}

# v2 endpoints
- endpoint:
    method: GET
    path: /api/v2/users
    response:
      status: 200
      body: >
        {
          "data": [{"id": 1, "fullName": "Alice Johnson"}],
          "meta": {"version": "2.0"}
        }

2. Header Versioning

- endpoint:
    method: GET
    path: /api/users
    response:
      status: 200
      headers:
        X-API-Version: "{{header-params.Accept-Version}}"
      body: >
        {
          "version": "{{header-params.Accept-Version}}",
          "users": []
        }

✅ Best Practices

• Use semantic versioning (v1, v2, v3)

• Maintain backward compatibility

• Document version differences

• Deprecate gradually
