This Telegram bot is designed to automate the sale and management of subscriptions for a Remnawave panel. It integrates with the Remnawave API for user and subscription management and uses YooKassa for processing payments.

✨ Features

User Interaction:
- User registration with language selection (English/Russian).
- Display of main menu with available actions via inline keyboards.
- Ability for users to view their current subscription status, expiration date, and configuration link.
- Trial subscription system for new users (configurable, manual activation via button).
- Promo code system for users to apply discounts or bonuses.
- Referral program for users to earn bonus subscription days.
Subscription Management:
- Handles subscription purchases for various periods (1, 3, 6, 12 months).
- Integrates with YooKassa for payment processing, including fiscal receipt data.
- Automatic subscription activation/extension upon successful payment.
- Link and syncs users with a Remnawave panel account, primarily matching by Telegram ID.
- Updates user status, expiration dates, traffic limits, and inbounds on the Remnawave panel.
Admin Panel:
- Protected by ADMIN_IDS (supports multiple administrators).
- Statistics: View bot usage (total users, banned, active subscriptions), recent payments, and panel sync status.
- User Management:
  - Ban/Unban users by Telegram ID or @username (updates local DB and panel).
  - View a paginated list of banned users.
  - View a "user card" with detailed information and unban option.
- Broadcast: Send messages to all users, users with active subscriptions, or users with expired subscriptions.
- Promo Codes: Create and view promo codes (bonus days, activation limits, validity).
- Panel Sync: Manually trigger synchronization of users and subscriptions from the Remnawave panel to the bot's database, matching by Telegram ID.
- Activity Logs: View a paginated list of all user actions (messages, commands, callbacks) or logs for a specific user.
Notifications:
- Automated daily notifications to users about expiring subscriptions (via APScheduler).
- Notifications to users and inviters upon successful referral bonus application.
- Notifications to admin(s) about suspicious promo code input attempts.
Security & Technical:
- Uses parameterized queries to prevent SQL injection.
- Proactive check for suspicious input in promo code field (notifies admin).
- Middleware for checking banned users on every interaction.
- Middleware for logging user actions.
- Webhook support for Telegram and YooKassa for efficient updates.
- Configurable via .env file.
- Dockerized for easy deployment.

🚀 Technologies Used

Python 3.11
Aiogram 3.x: Asynchronous Telegram Bot Framework
aiohttp: For running the webhook server
aiosqlite: Asynchronous SQLite database interaction
YooKassa SDK: For payment processing
APScheduler: For scheduled tasks (e.g., notifications)
Pydantic: For settings management (loading from .env)
Docker & Docker Compose: For containerization and deployment

⚙️ Setup and Configuration

Prerequisites

Docker and Docker Compose installed.
A running instance of a Remnawave panel.
A Telegram Bot Token.
A YooKassa Shop ID and Secret Key.

Configuration Steps

Clone the Repository (if applicable):

git clone https://github.com/machka-pasla/remnawave-tg-shop
cd remnawave-tg-shop

Create an .env File: Copy the env.example file to .env and fill in your specific values:
```
cp .env.example .env
nano .env 
```
Key variables to configure in .env:
- BOT_TOKEN: Your Telegram Bot Token from BotFather.
- ADMIN_IDS: Comma-separated list of your Telegram User IDs for admin access (e.g., 12345678,98765432). Crucial for bot management.
- DEFAULT_LANGUAGE: Default language for new users (e.g., ru or en).
- DEFAULT_CURRENCY_SYMBOL: e.g., RUB, USD.
- SUPPORT_LINK: (Optional) URL for a support chat/contact (e.g., https://t.me/your_support).
- SERVER_STATUS_URL: (Optional) URL to a server status page (e.g., Uptime Kuma).
- YooKassa Settings:
  - YOOKASSA_SHOP_ID: Your shop ID from YooKassa.
  - YOOKASSA_SECRET_KEY: Your secret key from YooKassa.
  - YOOKASSA_WEBHOOK_BASE_URL: Your publicly accessible HTTPS base URL where the bot will listen for YooKassa webhooks (e.g., https://your.domain.com). The full path will be {YOOKASSA_WEBHOOK_BASE_URL}/webhook/yookassa.
  - YOOKASSA_RETURN_URL: (Optional) URL user is redirected to after payment, often https://t.me/your_bot_username.
  - YOOKASSA_DEFAULT_RECEIPT_EMAIL: Important for 54-FZ (Russian fiscalization). A default email for sending fiscal receipts.
  - YOOKASSA_VAT_CODE: VAT code for items in receipt (e.g., 1 for "No VAT". Consult YooKassa documentation and tax advisor).
  - YOOKASSA_PAYMENT_MODE: e.g., full_prepayment.
  - YOOKASSA_PAYMENT_SUBJECT: e.g., service.
- TELEGRAM_WEBHOOK_BASE_URL: (Optional) If you want Telegram updates via webhook. Can be the same as YOOKASSA_WEBHOOK_BASE_URL. If not set, the bot will use polling for Telegram updates.
- PRICE_X_MONTH: Prices for different subscription durations.
- Panel API Settings:
  - PANEL_API_URL: Full URL to your Remnawave panel's API (e.g., http://localhost:3000/api or https://panel.yourdomain.com/api).
  - PANEL_API_KEY: API Key for authenticating with the Remnawave panel.
- PANEL_USER_DEFAULT_INBOUND_UUIDS: (Optional) Comma-separated list of inbound UUIDs from your panel to assign to users. If empty, activateAllInbounds: true (panel default) is used for new users.
- TRIAL_ENABLED, TRIAL_DURATION_DAYS, TRIAL_TRAFFIC_LIMIT_GB: Settings for the trial period.
- WEB_SERVER_HOST, WEB_SERVER_PORT: Host and port for the bot's internal webhook server.
- LOGS_PAGE_SIZE: For admin panel log pagination.
Locales:
- Translation files are in the locales/ directory (en.json, ru.json). Ensure they are present and correctly formatted. The bot_database.sqlite3 and locales directory will be mounted as volumes in Docker. locales mounting is optional.
Build and Run with Docker Compose:
```
docker compose up --build -d
```
This command will build the Docker image (if it doesn't exist or if Dockerfile changed) and start the vpn-shop service in detached mode.
Webhook Setup (Important if using webhooks):
- Reverse Proxy (Nginx, Caddy, etc.): You need a reverse proxy to handle incoming HTTPS traffic, manage SSL certificates (e.g., from Let's Encrypt), and forward requests to your bot's container.
  - Forward requests for https://{YOOKASSA_WEBHOOK_BASE_URL_domain}/webhook/yookassa to http://vpn-shop:{WEB_SERVER_PORT}/webhook/yookassa (where vpn-shop is the service name in docker-compose.yml).
  - If using Telegram webhooks, forward requests for https://{TELEGRAM_WEBHOOK_BASE_URL_domain}/<YOUR_BOT_TOKEN> to http://vpn-shop:{WEB_SERVER_PORT}/<YOUR_BOT_TOKEN>.
- Telegram Webhook Registration: The bot attempts to set its Telegram webhook URL on startup if TELEGRAM_WEBHOOK_BASE_URL is configured in .env. Check the bot logs to confirm if this was successful. You can also manually check using the Telegram Bot API method getWebhookInfo.
Database:
- A SQLite database file (bot_database.sqlite3) will be created in your project root (or wherever you map the volume). The schema is initialized automatically on the first run if the file doesn't exist.
Viewing Logs:
```
docker compose logs -f vpn-shop
```

🐳 Docker Setup

`Dockerfile`

FROM python:3.11-slim

WORKDIR /app

COPY requirements.txt .

# Consider adding build arguments for proxy if needed in your environment
# ARG HTTP_PROXY
# ARG HTTPS_PROXY
# ENV http_proxy=$HTTP_PROXY
# ENV https_proxy=$HTTPS_PROXY

RUN pip install --no-cache-dir -r requirements.txt

COPY . .

# Ensure main.py is executable if needed, though python command handles it
# RUN chmod +x main.py

CMD ["python", "main.py"]

`docker-compose.yml`

YAML

services:
  vpn-shop:
    build: .
    container_name: vpn-shop
    hostname: vpn-shop
    networks:
      - remnawave-network # Ensure this external network exists or define it
    volumes:
      - ./bot_database.sqlite3:/app/bot_database.sqlite3
    #   - ./locales:/app/locales
    restart: unless-stopped
    # Optionally, expose ports if you are not using a shared Docker network
    # and want to access the bot's webserver directly (not recommended for production without a reverse proxy)
    # ports:
    #   - "8080:8080" 

networks:
  remnawave-network:
    external: true # Assumes 'remnawave-network' is an existing external Docker network
                   # If not, you might want to define it here or use a default bridge.

Note on remnawave-network: The docker-compose.yml assumes an external network named remnawave-network. If this network doesn't exist or you want the bot on a different network (e.g., a default bridge or a new one defined in this compose file), you'll need to adjust the networks section. If the Remnawave panel is also running in Docker on the same host, putting them on the same user-defined network allows them to communicate using service names.
