Telegram to Google Drive Sync Bot

#csharp #telegram #telegrambot #googledrive #chat-bot

Project Goal:
The goal of the project was to implement full synchronization between a Telegram bot and Google Drive. The first bot allows users to create folders in Google Drive, upload photos directly through Telegram, and finish the session with a single click. The second bot is used to retrieve photos from the cloud by specifying the folder name.
