Goal

Develop integration of our chatbot service with Telegram via the Telegram Bot API. The integration should provide:

Receiving messages from users in Telegram.
Sending responses to users via Telegram.

The integration should be implemented as a separate module that interacts with our API.

Tasks

Creating the bot
- Set up the bot via BotFather.
- Ensure the possibility of integrating our service with user bots.
Authorization
- Implement a mechanism for transferring and storing the bot tokens provided by the user during registration.
- Ensure token validity checks before use.
Receiving messages
- Implement processing of incoming messages via the Telegram webhook.
- The webhook should receive events messages and transmit them in standard format through our API.
  Message format:
```
jsonCopy code{
  "message_id": "string",
  "sender_id": "string",
  "chat_id": "string",
  "timestamp": "ISO8601",
  "content": "string",
  "type": "text|image|video|document|sticker"
}
```
- Supported message types:
  - Text.
  - Images.
  - Videos.
  - Documents.
  - Stickers.
Sending messages
- Implement sending messages to users via the Telegram API.
- Supported response types:
  - Text.
  - Media files (images, videos).
  - Documents.
Bot commands
- Ensure the possibility of setting up custom commands (e.g., /start).
- Commands should be processed by the service and sent to our API.
Error handling
- Implement a mechanism for handling API errors (e.g., authorization errors, invalid data).
- In case of errors, log with a detailed description.
Testing
- Provide a test bot to demonstrate the integration functionality.
- Verify the correctness of receiving and sending messages, including considering different content types.
Documentation
- Provide documentation for the module, which includes:
  - Instructions for setting up the bot via BotFather.
  - Description of endpoints for integration.
  - Examples of requests and responses.

Technical requirements

Telegram API

Programming languages
