## Validation Features

### Standardized Error Responses

All endpoints return consistent error format:

```json
{
  "success": false,
  "error": "Validation failed",
  "errors": [
    {
      "field": "email",
      "message": "Field 'email' is required",
      "code": "REQUIRED"
    }
  ]
}
```

### Structured Logging

All validation failures are logged using `ordio_log()` with:

- Log level: `WARN`
- Context: Validation errors, input data, endpoint name
- Correlation IDs for request tracking

### Validation Rules

Each endpoint defines validation rules including:

- **Required fields:** Fields that must be present
- **Type checking:** email, string, integer, phone, url
- **Length limits:** min_length, max_length
- **Value constraints:** min_value, max_value, enum

## Benefits

1. **Security:** Prevents invalid data from reaching HubSpot API
2. **Consistency:** All endpoints use the same validation approach
3. **Debugging:** Structured error responses make issues easier to identify
4. **Maintainability:** Centralized validation logic in `request-validator.php`
5. **User Experience:** Clear, field-specific error messages

## Next Steps

- [ ] Add input sanitization to all endpoints
- [ ] Add CSRF protection for form submissions
- [ ] Create OpenAPI documentation for all endpoints
- [ ] Add integration tests for validation scenarios
