    What This Automation Does

    This bot handles everything your Telegram group or channel throws at it — automatically, without you touching a thing. Here's what it does the moment a message arrives: → Reads texts, photos, voice notes, and files — and sorts them instantly → Detects slash commands like /start, /pay, or /help and routes them to the right workflow → Registers new members into Google Sheets automatically → Processes payments and triggers invoice workflows → Sends fast, accurate replies back to users — no manual effort needed One n8n workflow. Every message type. Fully handled.  

    How the Workflow Works: Input → Process → Output

    Inputs

    • Telegram updates: Messages, files, callback queries, payments, and membership events.

    Processing Steps

    • A Telegram Trigger node receives all updates.
    • A Set node prepares data.
    • A main Switch node sorts input into categories: Message, Callback, System, Payment.
    • Within Message, another Switch finds if it is text, photo, file, or voice.
    • An IF node checks if text is a command starting with a slash.
    • A command Switch directs known commands to workflows; unknown commands get a fallback reply.
    • System inputs check for new member events; if found, an Execute Workflow updates Google Sheets to register the user.
    • Payment data triggers payment-related workflows after tagging action identifiers.

    Outputs

    • Replies sent back to Telegram chats confirming message types.
    • Google Sheets updated with user status.
    • Triggered workflows handle payments and invoices.

    Tools and Services Used

    • n8n platform: For building and running automation workflows.
