## API Category Template

Each new API category must follow this structure:

```
src/categories/[category-name]/
├── index.ts          # Main API class
├── types.ts          # TypeScript interfaces
├── schemas.ts        # Zod validation schemas  
├── tests/
│   ├── unit.test.ts  # Unit tests (95% coverage)
│   └── integration.test.ts # Integration tests
└── README.md         # Category documentation
```

## Integration Requirements

### Backward Compatibility
- [ ] Existing Product API must remain unchanged
- [ ] All breaking changes require migration guide
- [ ] Automated breaking change detection

### Quality Standards
- [ ] 95% test coverage minimum
- [ ] Type safety with Zod validation
- [ ] Performance: <200ms response times
- [ ] Documentation completeness

### Development Process
1. **Design Phase**
   - [ ] API design document
   - [ ] Schema definition  
   - [ ] Breaking change analysis

2. **Implementation Phase**
   - [ ] Core functionality
   - [ ] Type definitions
   - [ ] Comprehensive tests

3. **Integration Phase**
   - [ ] Main client integration
   - [ ] Documentation updates
   - [ ] Migration guide (if needed)

4. **Validation Phase**
   - [ ] Breaking change check
   - [ ] Performance validation
   - [ ] Bundle size check

## Risk Management

### High-Risk Categories
Categories that could impact existing functionality:
- [ ] **Core Client Changes** - Changes to main OzonSellerAPI class
- [ ] **HTTP Client Updates** - Changes to core HTTP functionality
- [ ] **Type System Changes** - Changes to base types

### Medium-Risk Categories  
Categories with moderate complexity:
- [ ] **Large API Surface** - Categories with >20 methods
- [ ] **Complex Dependencies** - Categories requiring significant dependencies
- [ ] **Performance Critical** - Categories handling high-volume operations

### Low-Risk Categories
Isolated categories with minimal impact:
- [ ] **Self-Contained APIs** - No dependencies on other categories
- [ ] **Simple Operations** - Basic CRUD operations only
- [ ] **Optional Features** - Non-essential functionality

## Quality Gates

Before any category can be marked as complete:

- [ ] **Breaking Change Check**: `npm run breaking:check` passes
- [ ] **Test Coverage**: `npm run test:coverage` shows ≥95%
- [ ] **Performance Test**: `npm run test:performance` passes
- [ ] **Bundle Size**: `npm run bundle:check` within limits
- [ ] **Risk Assessment**: `npm run risk:assess` acceptable
- [ ] **Documentation**: Complete API documentation
- [ ] **Integration Test**: Works with main client
