+
+## Global HTTP Headers
+
+The frontend **automatically attaches** two custom headers to **every API request** via an interceptor. The backend should read these headers and use them to filter/translate responses accordingly.
+
+| Header        | Example Value | Description                                                |
+|---------------|---------------|------------------------------------------------------------|
+| `X-Region`    | `moscow`      | Region ID selected by the user. **Absent** = global (all). |
+| `X-Language`  | `ru`          | Active UI language: `ru`, `en`, or `hy`.                   |
+
+### Backend behavior
+
+- **`X-Region`**: If present, filter items/categories to only those available in that region. If absent, return everything (global catalog).
+- **`X-Language`**: If present, return translated `name`, `description`, etc. for categories/items when translations exist. If absent or `ru`, use russians defaults.
+
+### CORS requirements for these headers
+
+```
+Access-Control-Allow-Headers: Content-Type, X-Region, X-Language
+```
+
+---
+
+## 1. Health Check
+
+### `GET /ping`
+
+Simple health check.
+
+**Response `200`:**

+{ "message": "pong" }
+```

+---
+
+## 2. Catalog — Categories
+
+### `GET /category`
+
+Returns all top-level categories. Respects `X-Region` and `X-Language` headers.
+

+> **Fallback:** If this endpoint is down, the frontend uses 6 hardcoded defaults: Moscow, SPB, Yerevan, Minsk, Almaty, Tbilisi.
+
+---
+
+## 8. Authentication (Telegram Login)
+
+Authentication is **Telegram-based** with **cookie sessions** (HttpOnly, Secure, SameSite=None).
+
+All auth endpoints must include `withCredentials: true` CORS support.
+
+### Auth flow
+
+```
+1. User clicks "Checkout" → not authenticated → login dialog shown
+2. User clicks "Log in with Telegram" → opens https://t.me/{bot}?start=auth_{callback}
+3. User starts the bot in Telegram
+4. Bot sends user data → backend /auth/telegram/callback
+5. Backend creates session → sets Set-Cookie
+6. Frontend polls GET /auth/session every 3s
+7. Session detected → dialog closes → checkout proceeds
+```
+
+---
+
+### `GET /auth/session` — Check current session
+
+**Request:** Cookies only (session cookie set by backend).
+
+**Response `200`** (authenticated):
+```json
+{
+  "sessionId": "sess_abc123",
+  "telegramUserId": 123456789,
+  "username": "john_doe",
+  "displayName": "John Doe",
+  "active": true,
+  "expiresAt": "2026-03-01T12:00:00Z"
+}
+```
+
+**Response `200`** (expired):
+```json
+{
+  "sessionId": "sess_abc123",
+  "telegramUserId": 123456789,
+  "username": "john_doe",
+  "displayName": "John Doe",
+  "active": false,
+  "expiresAt": "2026-02-27T12:00:00Z"
+}
+```
+
+**Response `401`** (no session):
+```json
+{ "error": "No active session" }
+```
+
+**AuthSession object:**
+
+| Field            | Type    | Required | Description                                |
+|------------------|---------|----------|--------------------------------------------|
+| `sessionId`      | string  | yes      | Unique session ID                          |
+| `telegramUserId` | number  | yes      | Telegram user ID                           |
+| `username`       | string? | no       | Telegram @username (can be null)           |
+| `displayName`    | string  | yes      | User display name (first + last)           |
+| `active`         | boolean | yes      | Whether session is valid                   |
+| `expiresAt`      | string  | yes      | ISO 8601 expiration datetime               |
+
+---
+
+### `GET /auth/telegram/callback` — Telegram bot auth callback
+
+Called by the Telegram bot after user authenticates.
+
+**Request body (from bot):**
+```json
+{
+  "id": 123456789,
+  "first_name": "John",
+  "last_name": "Doe",
+  "username": "john_doe",
+  "photo_url": "https://t.me/i/userpic/...",
+  "auth_date": 1709100000,
+  "hash": "abc123def456..."
+}
+```
+
+**Response:** Must set a session cookie and return:
+```json
+{
+  "sessionId": "sess_abc123",
+  "message": "Authenticated successfully"
+}
+```
+
+**Cookie requirements:**
+
+| Attribute  | Value          | Notes                                      |
+|------------|----------------|--------------------------------------------|
+| `HttpOnly` | `true`         | Not accessible via JS                      |
+| `Secure`   | `true`         | HTTPS only                                 |
+| `SameSite` | `None`         | Required for cross-origin (API ≠ frontend) |
+| `Path`     | `/`            |                                            |
+| `Max-Age`  | `86400` (24h)  | Or as needed                               |
+
+---
+
+### `POST /auth/logout` — End session
+
+**Request:** Cookies only, empty body `{}`
+
+**Response `200`:**
+```json
+{ "message": "Logged out" }
+```
+
+Must clear/invalidate the session cookie.
+
+---
+
+### Session refresh
+
+The frontend re-checks the session **60 seconds before `expiresAt`**. If the backend supports sliding expiration, it can reset the cookie's `Max-Age` on each `GET /auth/session`.
+
+---
+
+## 9. i18n / Translations
+
+The frontend supports 3 languages: **Russian (ru)**, **English (en)**, **Armenian (hy)**.
+
+The active language is sent via the `X-Language` HTTP header on every request.
+
+### What the backend should do with `X-Language`
+
+1. **Categories & items**: If `translations` field exists for the requested language, return the translated `name`, `description`, etc. OR the backend can apply translations server-side and return already-translated fields.
+
+2. **The `translations` field** on items (optional approach):
+   ```json
+   {
+     "translations": {
+       "en": {
+         "name": "iPhone 15 Pro",
+         "simpleDescription": "Short desc in English",
+         "description": [{ "key": "Processor", "value": "A17 Pro" }]
+       },
+       "hy": {
+         "name": "iPhone 15 Pro",
+         "simpleDescription": "Կarcheck check"
+       }
+     }
+   }
+   ```
+
+3. **Recommended approach**: Read `X-Language` header and return the `name`/`description` in that language directly. If no translation exists, return the Russian default.
+
+---
+
+## 10. CORS Configuration
+
+For auth cookies and custom headers to work, the backend CORS config must include:
+
+```
+Access-Control-Allow-Origin: https://dexarmarket.ru    (NOT wildcard *)
+Access-Control-Allow-Credentials: true
+Access-Control-Allow-Headers: Content-Type, X-Region, X-Language
+Access-Control-Allow-Methods: GET, POST, PATCH, DELETE, OPTIONS
+```
+
+> **Important:** `Access-Control-Allow-Origin` cannot be `*` when `Allow-Credentials: true`. Must be the exact frontend origin.
+
+**Allowed origins:**
+- `https://dexarmarket.ru`
+- `https://novo.market`
+- `http://localhost:4200` (dev)
+- `http://localhost:4201` (dev, Novo)
+
+---
+
+## 11. Telegram Bot Setup
+
+Each brand needs its own bot:
+- **Dexar:** `@dexarmarket_bot`
+- **Novo:** `@novomarket_bot`
+
+The bot should:
+1. Listen for `/start auth_{callbackUrl}` command
+2. Extract the callback URL
+3. Send the user's Telegram data (`id`, `first_name`, `username`, etc.) to that callback URL
+4. The callback URL is `{apiUrl}/auth/telegram/callback`

+| `POST`   | `/purchase-email`     | Submit email after pay   | No   | —                  |
+
+> \* Cart/payment endpoints may use the session cookie if available for order association, but don't strictly require auth. The frontend enforces auth before checkout.

+## Базовые URL
+
+| Бренд  | Dev                              | Production                       |

+
+## Глобальные HTTP-заголовки
+
+Фронтенд **автоматически добавляет** два кастомных заголовка к **каждому API-запросу** через interceptor. Бэкенд должен читать эти заголовки и использовать для фильтрации/перевода ответов.
+
+| Заголовок     | Пример значения | Описание                                                          |
+|---------------|-----------------|-------------------------------------------------------------------|
+| `X-Region`    | `moscow`        | ID региона, выбранного пользователем. **Отсутствует** = все регионы. |
+| `X-Language`  | `ru`            | Активный язык интерфейса: `ru`, `en` или `hy`.                   |
+
+### Поведение бэкенда
+
+- **`X-Region`**: Если присутствует — фильтровать товары/категории только по этому региону. Если отсутствует — возвращать всё (глобальный каталог).
+- **`X-Language`**: Если присутствует — возвращать переведённые `name`, `description` и т.д., если переводы существуют. Если отсутствует или `ru` — возвращать на русском (по умолчанию).
+
+### Требования CORS для этих заголовков
+
+```
+Access-Control-Allow-Headers: Content-Type, X-Region, X-Language
+```
+
+---
+
+## 1. Проверка состояния
+
+### `GET /ping`

+
+## 8. Авторизация (вход через Telegram)
+
+Авторизация **через Telegram** с **cookie-сессиями** (HttpOnly, Secure, SameSite=None).
+
+Все auth-эндпоинты должны поддерживать CORS с `credentials: true`.
+
+### Процесс авторизации
+
+```
+1. Пользователь нажимает «Оформить заказ» → не авторизован → показывается диалог входа
+2. Нажимает «Войти через Telegram» → открывается https://t.me/{bot}?start=auth_{callback}
+3. Пользователь запускает бота в Telegram
+4. Бот отправляет данные пользователя → бэкенд /auth/telegram/callback
+5. Бэкенд создаёт сессию → устанавливает Set-Cookie
+6. Фронтенд опрашивает GET /auth/session каждые 3 секунды
+7. Сессия обнаружена → диалог закрывается → оформление заказа продолжается
+```
+
+---
+
+### `GET /auth/session` — Проверить текущую сессию

+Фронтенд повторно проверяет сессию за **60 секунд до `expiresAt`**. Если бэкенд поддерживает скользящий срок действия (sliding expiration), можно обновлять `Max-Age` cookie при каждом вызове `GET /auth/session`.
+
+---
+
+## 9. i18n / Переводы
+
+Фронтенд поддерживает 3 языка: **Русский (ru)**, **Английский (en)**, **Армянский (hy)**.
+
+Активный язык отправляется через HTTP-заголовок `X-Language` с каждым запросом.
+
+### Что бэкенд должен делать с `X-Language`
+
+1. **Категории и товары**: Если для запрошенного языка есть поле `translations`, вернуть переведённые `name`, `description` и т.д. ИЛИ бэкенд может применять переводы на стороне сервера и возвращать уже переведённые поля.
+
+2. **Поле `translations`** на товарах (опциональный подход):
+   ```json
+   {
+     "translations": {
+       "en": {
+         "name": "iPhone 15 Pro",
+         "simpleDescription": "Short desc in English",
+         "description": [{ "key": "Processor", "value": "A17 Pro" }]
+       },
+       "hy": {
+         "name": "iPhone 15 Pro",
+         "simpleDescription": "Կarcheck check"
+       }
+     }
+   }
+   ```
+
+3. **Рекомендуемый подход**: Читать заголовок `X-Language` и возвращать `name`/`description` на этом языке напрямую. Если перевода нет — возвращать русский вариант по умолчанию.
+
+---
+
+## 10. Настройка CORS
+
+Для работы auth-cookie и кастомных заголовков конфигурация CORS бэкенда должна включать:
+
+```
+Access-Control-Allow-Origin: https://dexarmarket.ru    (НЕ wildcard *)
+Access-Control-Allow-Credentials: true
+Access-Control-Allow-Headers: Content-Type, X-Region, X-Language
+Access-Control-Allow-Methods: GET, POST, PATCH, DELETE, OPTIONS
+```
+
+> **Важно:** `Access-Control-Allow-Origin` не может быть `*` при `Allow-Credentials: true`. Должен быть точный origin фронтенда.
+
+**Разрешённые origins:**
+- `https://dexarmarket.ru`
+- `https://novo.market`
+- `http://localhost:4200` (dev)
+- `http://localhost:4201` (dev, Novo)
+
+---
+
+## 11. Настройка Telegram-бота
+
+Каждому бренду нужен свой бот:
+- **Dexar:** `@dexarmarket_bot`
+- **Novo:** `@novomarket_bot`
+
+Бот должен:
+1. Слушать команду `/start auth_{callbackUrl}`
+2. Извлечь callback URL
+3. Отправить данные пользователя (`id`, `first_name`, `username` и т.д.) на этот callback URL
+4. Callback URL: `{apiUrl}/auth/telegram/callback`

+bro we need to do changes, that client required
+1. we need to add location logic
+1.1 the catalogs will come or for global or for exact region
+1.2 need to add a place where the user can choose his region like city if choosed moscow the country is set russian
+1.3 can we try to understand what country is user logged or whach city by global ip and set it?
+2. we need to add somekind of user login logic
+2.1 user can add to cart, look the items and etc without logged in, but when he is going to buy/pay ->
+  at first he have to login with telegram, i will send you the bots adress.
+  2.1.1 if is not logged -> will see the QR or link for logging via telegram
+  2.1.2 if logged we need to ping server to check if he is active user. the expiration date (like day or 5 days) we will get from bakcend with session id
+2.2 and when user is logged, that time he can do a payment
