## 🔍 Data Validation Services

### 1. DaData Integration

**Статус:** ✅ **ПОЛНОСТЬЮ АКТИВНА** (обновлено 10.09.2025)

DaData API успешно интегрирован и используется для валидации ИНН при регистрации организаций. Включает полную валидацию контрольных сумм и проверку активности организаций.

#### Реализация в проекте

**Основной сервис:** `/src/services/dadata-service.ts`
**GraphQL интеграция:** `/src/graphql/resolvers/domains/user-management.ts`

```typescript
// src/services/dadata-service.ts
export class DaDataService {
  private apiKey: string
  private apiUrl: string

  constructor() {
    const apiKey = process.env.DADATA_API_KEY
    const apiUrl = process.env.DADATA_API_URL

    if (!apiKey || !apiUrl) {
      throw new Error('DaData API credentials not configured')
    }
    
    this.apiKey = apiKey
    this.apiUrl = apiUrl
  }

  // Получает информацию об организации по ИНН с полной валидацией
  async getOrganizationByInn(inn: string): Promise<OrganizationData | null> {
    try {
      const response = await axios.post<DaDataResponse>(
        `${this.apiUrl}/findById/party`,
        {
          query: inn,
          count: 1,
        },
        {
          headers: {
            Authorization: `Token ${this.apiKey}`,
            'Content-Type': 'application/json',
            Accept: 'application/json',
          },
        },
      )

      if (!response.data?.suggestions?.length) {
        return null
      }

      const company = response.data.suggestions[0]

#### GraphQL Integration

```typescript
// src/graphql/resolvers/domains/user-management.ts
verifyInn: async (_: unknown, args: { inn: string }) => {
  console.log('🔍 VERIFY_INN STARTED:', { inn: args.inn })

  // Базовая проверка длины ИНН
  if (!args.inn || (args.inn.length !== 10 && args.inn.length !== 12)) {
    return {
      success: false,
      message: 'Некорректный ИНН. ИНН должен содержать 10 или 12 цифр',
      organization: null,
    }
  }

  try {
    // Валидация ИНН по контрольной сумме
    if (!dadataService.validateInn(args.inn)) {
      return {
        success: false,
        message: 'Некорректный ИНН. Проверьте правильность введенных цифр',
        organization: null,
      }
    }

    // Получение данных из DaData
    const organizationData = await dadataService.getOrganizationByInn(args.inn)

    if (!organizationData) {
      return {
        success: false,
        message: 'Организация с таким ИНН не найдена',
        organization: null,
      }
    }

    // Проверка активности организации
    if (!organizationData.isActive) {
      return {
        success: false,
        message: 'Организация не активна или ликвидирована',
        organization: null,
      }
    }

    return {
      success: true,
      message: 'ИНН верифицирован успешно',
      organization: {
        name: organizationData.name,
        fullName: organizationData.fullName,
        address: organizationData.address,
        isActive: organizationData.isActive,
      },
    }
  } catch (error) {
    console.error('💥 VERIFY_INN ERROR:', error)
    return {
      success: false,
      message: 'Ошибка при проверке ИНН. Попробуйте позже',
      organization: null,
    }
  }
}
```

#### Результаты тестирования (10.09.2025)

**✅ Успешно протестированные ИНН:**
- `7743291031` → "А-Я ЛОГИСТИКА" (активная организация)
- `7736207543` → "ЯНДЕКС" (активная организация)  
- `7702070139` → "БАНК ВТБ" (активная организация)

**✅ Валидация ошибок:**
- `1234567890` → "Некорректный ИНН. Проверьте правильность введенных цифр" (не прошел контрольную сумму)

**✅ End-to-End тестирование:**
- Полный цикл регистрации организации работает: SMS → Phone Verification → INN Validation → Organization Creation
