Role-based access control (RBAC) for Telegram automations

🔐 n8n Workflow: Role-Based Access Control (RBAC) for Telegram Automations

This n8n workflow lets you control access to your internal Telegram bots and automation systems based on user roles and departments. It ensures that only authorized team members — defined in your employee database — can interact with specific parts of your workflow. Perfect for agencies, internal tools, or multi-team organizations where permissions differ across roles (e.g., Marketing, Sales, Administration).

📌 Section 1: Trigger & Input

⚡ Receive Message (Telegram Trigger) Purpose: Captures incoming messages from users interacting with your Telegram bot.

How it works:

When a user sends any message to the bot, the workflow retrieves their Telegram username and triggers the process.

Benefit:

Provides a secure and instant entry point for validating user identity before running any internal logic.

📌 Section 2: Role Lookup

📋 Employee Database (Data Table Node) Purpose: Fetches user details such as Position and Type from your internal employee table.

Structure Example:

UserName===Position===Type User_1===Marketing===SEO User_2===Administration===Manager User_3===Marketing===Target

Benefit:

Centralized employee management — you can update access levels (roles or departments) directly in the data table without editing the workflow.

📌 Section 3: Position & Role Check

🧩 Choose Position (Switch Node)

Purpose: Determines the user’s department or role level (e.g., Marketing, Sales, Administration).

🧩 Check Role Type (Switch Node)

Purpose: Performs a second-level check — filters users by Type (e.g., SEO, SMM, Target).

Logic:

Marketing → SEO → Send to SEO workflow branch Marketing → Target → Send to Ads branch Administration → Manager → Grant full access Sales → Employee → Limited access

Benefit:

Allows multi-level, role-based logic with different automation paths for each team or position.

📌 Section 4: Action Routing

💬 No Operation Nodes (Placeholders) Purpose: Represent different action branches — each can later be replaced with the logic specific to that department.

Examples:

“Target” branch → connect to ad performance automation “SEO” branch → connect to Google Search Console reports “Sales” branch → connect to CRM updates

Benefit:

A flexible access framework — ready to integrate with any process per department.
