+# NetworkService — полная карта API-вызовов
+
+[← Главная](../index.md)
+
+Все HTTP-вызовы, выполняемые приложением. Класс `NetworkService` (`services/net/NetworkService.h/cpp`).
+
+---
+
+## Аутентификация
+
+| Метод | Путь | Слот | Описание |
+|-------|------|------|----------|
+| POST | `/api/v1/auth/login` | `loginAndSetup()` | Вход по `api_key`, получение токенов |
+| POST | `/api/v1/auth/refresh_token` | `refreshToken()` (private) | Обновление access_token |
+
+Токены сохраняются в `config.ini`. Авто-рефреш за 30 минут до истечения — `scheduleNextRefresh()`.
+
+---
+
+## Desktop
+
+| Метод | Путь | Слот | Описание |
+|-------|------|------|----------|
+| POST | `/api/v1/desktop/` | `loginAndSetup()` | Создание desktop при первом запуске (если `desktop_id` не сохранён) |
+
+Ответ: сохраняет `desktop_id` и `profile_id` в `config.ini`.
+
+---
+
+## Device
+
+| Метод | Путь | Слот | Описание |
+|-------|------|------|----------|
+| POST | `/api/v1/device/` | `createDevice()` | Регистрация нового Android устройства |
+| PATCH | `/api/v1/device/{api_id}` | `updateDevice()` | Обновление статуса/батареи устройства |
+| POST | `/api/v1/device/add_screenshot/{api_id}` | `postDeviceScreenshot()` | Загрузка скриншота (`multipart/form-data`, `image/jpeg`) |
+
+`api_id` — UUID, получаемый при создании и сохраняемый в таблице `devices`.
+
+---
+
+## Profile / Material
+
+| Метод | Путь | Слот | Описание |
+|-------|------|------|----------|
+| POST | `/api/v1/profile/bank_profile` | `postBankProfile()` | Создать банк-профиль |
+| PATCH | `/api/v1/profile/bank_profile/{id}` | `patchBankProfile()` | Обновить банк-профиль |
+| POST | `/api/v1/profile/material` | `postMaterial()` | Создать материал (карту) |
+
+`postBankProfile` сохраняет `bank_profile_id` в таблице `applications`.
+`postMaterial` сохраняет `material_id` (UUID) в таблице `accounts`.
+
+---
+
+## Tasks
+
+| Метод | Путь | Слот | Auth | Описание |
+|-------|------|------|------|----------|
+| GET | `/api/v1/task/get_tasks` | `getTasks()` | Bearer | Получить очередь задач (поллинг каждые 5 сек) |
+| POST | `/api/v1/task/task_result` | `postTaskResult()` | Bearer | Отправить результат задачи |
+
+`getTasks()` — асинхронный (без QEventLoop), использует сигнал `tasksReceived(QJsonArray)`.
+`postTaskResult()` — вызывается из `sendTaskResult()` в `EventHandler` в отдельном QThread.
+
+---
+
+## Устаревшие эндпоинты (legacy)
+
+Используют старый `multipart/form-data` API с токеном в теле. Пути задаются в `config.ini` напрямую как полные URL.
+
+| Слот | Ключ в config.ini | Статус |
+|------|-------------------|--------|
+| `postEventStatus()` | `net/eventStatusUpdate` | ⚠️ устарел, используется в `updateEventThread` |
+| `postAppStatus()` | `net/appStatusUpdate` | используется при смене статуса приложения |
+| `insertTransactionData()` | `net/transactionInsert` | создание транзакции |
+| `updateTransactionData()` | `net/transactionUpdate` | обновление транзакции |
+| `getPayments()` | `net/paymentsGet` | ⚠️ старый поллинг задач (заменён на `getTasks`) |
+
+---
+
+## Конфигурация путей (`config.ini`)
+
+```ini
+[net]
+apiBase           = http://localhost:9999
+pathAuthLogin     = /api/v1/auth/login
+pathAuthRefresh   = /api/v1/auth/refresh_token
+pathDesktopCreate = /api/v1/desktop/
+pathDevice        = /api/v1/device/
+pathDeviceScreenshot = /api/v1/device/add_screenshot/
+pathBankProfile   = /api/v1/profile/bank_profile
+pathMaterial      = /api/v1/profile/material
+pathGetTasks      = /api/v1/task/get_tasks
+pathTaskResult    = /api/v1/task/task_result
+```
+
+Если ключ отсутствует — используется значение по умолчанию (захардкожено в конструкторе `NetworkService`).
+
+---
+
+## Авторизация в запросах
+
+- **Bearer** — `Authorization: Bearer <access_token>` из `config.ini [common/access_token]`
+- **Legacy** — поле `token` в multipart-теле (из `config.ini [common/token]`)
