Telegram Task Management

Field	Documentation
Automation Title	Telegram Task Management & Reminder System
Category	Operations / Project Management
Detailed Description	This automation streamlines task management by allowing teams to assign and track tasks directly through Telegram, with automatic reminders and centralized tracking in Google Sheets. It solves the problem of scattered task assignments across multiple chat platforms and missed deadlines by providing a structured system that captures tasks from Telegram conversations, stores them in an organized spreadsheet, and sends proactive reminders as deadlines approach. The system is designed for team leads, project managers, and team members who need to coordinate tasks efficiently without switching between multiple applications. Expected outcomes include improved task completion rates, reduced missed deadlines, and centralized task visibility.
How It Works (Functionality)	Trigger 1 (Daily Reminders):
Cron schedule → Read Google Sheets → Calculate Reminders (Code node) → Send Telegram reminders
Trigger 2 (Task Management):
Telegram message → Parse message (Code node) → Validate task → Branch: [New task → Log to Sheets → Send confirmation] OR [Status update → Update Sheets → Send confirmation]
