n8n tutorial - Lesson 28: Build a RAG Chatbot with n8n Pinecone and Telegram

Hi everyone, in this post I'll show you how to build a RAG chatbot that answers questions over Telegram using n8n, Pinecone, and Claude Haiku — a practical n8n RAG pipeline tutorial from real session notes. This is part of the n8n Workflow Automation Tutorial series, and by the end you'll have a working Telegram bot that queries your Pinecone knowledge base on demand.

How to do:

Step 1 — Prepare the RAG Query Sub-Workflow

Before building the Telegram-facing workflow, you need to make your existing RAG query workflow callable by other workflows in n8n.
  1. Open your existing RAG query workflow — in this series it is named T8-B2-RAG-Query.
  2. Add a new trigger node: search for and select When Executed by Another Workflow.
  3. Inside that trigger node, define one input field:
    • Field name: query
    • Field type: String
  4. Save the workflow and set its status to Active.

Note — The Call n8n Workflow tool node only lists sub-workflows that have a When Executed by Another Workflow trigger. If your workflow uses a Chat Trigger or Manual Trigger only, it will not appear in the tool's dropdown. You must add this trigger and declare the input schema for the workflow to be usable as a tool.

Step 2 — Create the RAG Telegram Workflow

This step builds the main workflow — T8-B3-RAG-Telegram — that receives a Telegram message and routes it through an AI Agent with Pinecone-backed RAG.
  1. Create a new workflow and name it T8-B3-RAG-Telegram.
  2. Add a Telegram Trigger node as the entry point. Configure it with your Telegram bot token so it listens for incoming messages.
  3. Add an AI Agent node and connect it to the Telegram Trigger output.
    • Set the model to Claude Haiku 4.5 (or your preferred model credential).
    • Pass the user's message from the trigger as the agent's input prompt.
  4. Inside the AI Agent's Tools section, add a Call n8n Workflow tool.
  5. In the Call n8n Workflow tool, select T8-B2-RAG-Query from the workflow list and map the query field to the incoming user message.
  6. Add a Telegram node at the end, set the action to Send Message, and map the Chat ID and the AI Agent's output text as the message body.
  7. Save and set the workflow to Active.

Tip — When mapping the Chat ID for the reply, use the value from the Telegram Trigger output — typically $json.message.chat.id. This ensures the bot always replies to the correct conversation thread.

Step 3 — Test the End-to-End RAG Chatbot

With both workflows active, send a real message through Telegram to confirm the full pipeline works.
  1. Open Telegram and find your bot.
  2. Send a question that is covered by your Pinecone knowledge base.
  3. Confirm that:
    • The Telegram Trigger fires and passes the message to the AI Agent.
    • The AI Agent calls T8-B2-RAG-Query with the query field populated.
    • The RAG query retrieves relevant context from Pinecone and returns it to the agent.
    • The agent composes a response and the Telegram send node delivers it back to the chat.
  4. Check the execution logs in n8n for each workflow to verify no errors occurred.

Tip — If the bot replies but the answer is not grounded in your knowledge base, check that the T8-B2-RAG-Query workflow is returning results correctly by running it manually with a test query value first.

Step 4 — Set Up a Cloudflare Named Tunnel (for a Stable Webhook URL)

A named Cloudflare Tunnel gives your local n8n instance a permanent public HTTPS URL, so Telegram webhooks never break on restart — unlike Quick Tunnel which generates a new URL every time.
  1. Log in to your Cloudflare account and add your domain (e.g. dan14.vn) on the free plan.
  2. At your domain registrar, replace the existing nameservers with the two Cloudflare nameservers provided — for example:
    • brenna.ns.cloudflare.com
    • hasslo.ns.cloudflare.com
  3. Wait for DNS propagation — typically 1–2 hours but can take up to 24 hours. Cloudflare will send a confirmation email when the domain is active.
  4. Once you receive the "your domain is now active on Cloudflare" email, open a terminal and run:
    1. cloudflared tunnel login — a browser window opens; select your domain and click Authorize.
    2. cloudflared tunnel create n8n-tunnel — note the Tunnel ID that is returned.
    3. cloudflared tunnel route dns n8n-tunnel n8n.dan14.vn — this creates a CNAME record in your Cloudflare DNS automatically.
  5. Create the tunnel config file at C:\Users\<user>\.cloudflared\config.yml with the following content: 
    tunnel: <TUNNEL_ID>
credentials-file: C:\Users\<user>\.cloudflared\<TUNNEL_ID>.json
ingress:
  - hostname: n8n.dan14.vn
    service: http://localhost:5678
  - service: http_status:404
  6. Start the tunnel by running: cloudflared tunnel run n8n-tunnel

Note — The last ingress rule — service: http_status:404 — is required as a catch-all. Cloudflare will reject the config if no catch-all rule is present.

Step 5 — Update n8n Webhook URL and Restart

After the tunnel is live, update n8n's environment config so all webhooks use the new permanent domain.
  1. Open your Docker Compose file at D:\n8n\docker-compose.yml.
  2. Find the WEBHOOK_URL environment variable and set it to: https://n8n.dan14.vn
  3. Save the file and restart Docker:
    • Run docker compose down then docker compose up -d in the same directory.
  4. In n8n, deactivate and reactivate any webhook-based workflows — for example T7-B2-Telegram-Chatbot and T8-B3-RAG-Telegram — so they re-register with the new URL.

Production tip — Always deactivate then reactivate webhook workflows after changing WEBHOOK_URL. n8n caches the webhook registration URL at activation time, so existing active workflows will still point to the old address until you cycle them.

Key Lessons from This Session

  1. Sub-workflows must have a "When Executed by Another Workflow" trigger to appear as a callable tool. Chat Trigger and Manual Trigger are not recognized by the Call n8n Workflow tool node — you must add this specific trigger and declare the input schema.
  2. Named Tunnels require your domain to be managed inside Cloudflare DNS. Quick Tunnel works without a domain but the URL changes on every restart, breaking all registered webhooks.
  3. The Cloudflare tunnel setup order matters: add domain → change nameservers → wait for propagation → login with cloudflared → create tunnel → route DNS → write config → run tunnel.
  4. Reactivating workflows after a webhook URL change is mandatory. n8n does not automatically re-register webhooks when the environment variable changes.

Conclusion:

In this n8n RAG pipeline tutorial, you built a fully functional RAG chatbot on Telegram by chaining a Telegram Trigger, an AI Agent, and a callable RAG sub-workflow backed by Pinecone — a key milestone in this n8n workflow automation series. You also learned how to give your local n8n instance a stable public URL using a Cloudflare Named Tunnel, which is essential for reliable webhook-based workflows in production. Next session, the focus shifts to completing the Named Tunnel setup and verifying the permanent webhook URL end-to-end.

Integrating Google Calendar into n8n Using OAuth2: A Complete Setup Guide

On

n8n is an open-source workflow automation platform that lets you connect hundreds of applications together without writing complicated code. Here's what's interesting: once you integrate Google Calendar into n8n, every change to your schedule—a new event, a cancellation, a time shift—can become the starting trigger for an automated workflow that handles everything downstream.

To make this work, n8n requires OAuth2 credentials that you create yourself on Google Cloud. The process sounds intimidating at first, but it really only takes 10-15 minutes if you follow the steps below carefully.

Connecting Google Calendar to n8n: Step-by-Step

Step 1: Add the Google Calendar Node to Your Workflow

Open n8n and create a new workflow. Click the Add first step button in the center of your screen. In the search bar that appears on the right, type calen to filter your options. You'll see suggestions including Calendly and Google Calendar—select Google Calendar.


Step 2: Choose Your Trigger or Action

After selecting Google Calendar, n8n displays all available features organized into two categories. The Triggers section contains 5 types of event-based activators: On event cancelled, On event created, On event ended, On event started, and On event updated. The Actions section includes 6 direct actions you can perform on your calendar. Pick the trigger that matches your workflow goal. For example, choose On event started if you want your workflow to run the moment an event begins.


Step 3: Open the Credential Settings

Your Google Calendar Trigger node appears with a configuration panel on the right. In the Credential field, you'll see "No credentials" with a red warning icon. Click the Set up credential button in the bottom right corner to begin authentication.

A Google Calendar account window opens, displaying your OAuth Redirect URL in the format http://localhost:5678/rest/oauth2-credential/callback. Copy this URL now—you'll need it in the next step. Click Click To Copy for a quick copy.


Step 4: Create a New Project on Google Cloud

Open your browser and navigate to console.cloud.google.com. Click your current project name in the top navigation bar to open the project selector. Click New project in the upper right corner.

On the new project creation page, enter a name in the Project name field—something like n8n-QTM-CLD works well. The Project ID generates automatically and cannot be changed afterward. Click Create to finish.


Step 5: Select Your New Project

Once your project is created, Google Cloud shows a success notification in the Notifications area (bottom right corner). Click Select Project in that notification to switch to your new project. The navigation bar title updates to reflect your new project name.


Step 6: Enable the Google Calendar API

In Google Cloud Console, go to APIs & Services and select Library. Alternatively, use the search bar next to your project name and search for Google Calendar API, then open its detail page. Click the Enable button to activate the API for your project. Once enabled, the page switches to the API management dashboard with tabs for Overview, Documentation, and Support.


Step 7: Configure the OAuth Consent Screen

Go to APIs & Services and select OAuth consent screen. You'll see a message saying "Google Auth Platform not configured yet." Click Get started to begin configuration.

The setup includes 4 short steps. In the App Information step, enter an app name in the App name field—for example, n8n-QTM-Calendar. Select a support email address in the User support email field. Click Next.

On the Audience step, keep the default setting as External since you're using a personal Google account. Click Next.

On the Contact Information step, enter an email address where Google can notify you of any project-related changes. Click Next.

On the Finish step, check the box to agree with Google API Services User Data Policy, then click Continue. Next, click Create OAuth client to complete the consent screen setup.


Step 8: Create Your OAuth Client ID

After your consent screen is ready, the OAuth Overview page displays a Metrics section indicating no OAuth client exists yet. Click Create OAuth client to begin.

On the Create OAuth client ID page, set Application type to Web application (item 1 in the screenshot). Enter a name in the Name field—for example, Web client 1 (item 2).

Scroll down to the Authorized redirect URIs section. Click Add URI and paste the callback URL you copied from n8n in Step 3—specifically, http://localhost:5678/rest/oauth2-credential/callback. Click Create.


Step 9: Copy Your Client ID and Client Secret

Google Cloud displays an "OAuth client created" dialog with complete details. Copy both your Client ID and Client Secret right now—after you close this dialog, you won't be able to view your Client Secret again. You can also download a JSON file for secure storage using the Download JSON button.


Step 10: Enter Your Credentials in n8n and Sign In

Return to n8n and paste your Client ID and Client Secret into the corresponding fields in the Google Calendar account window. Click Sign in with Google to complete the connection.

Troubleshooting the "Access blocked" Error

If you encounter an error message saying "Access blocked: [app name] has not completed the Google verification process" with code Error 403: access_denied, you've hit a common issue. This happens when your app is in Testing mode and you haven't added your account to the test user list.

Here's how to fix it: Return to Google Cloud Console and go to APIs & Services → OAuth consent screen. Select the Audience tab from the left menu (item 1 in image 20). Click Add users (item 2), enter your Gmail address in the email field (item 3), then click Save (item 4). Go back to n8n and try signing in with Google again.

Check the boxes to grant n8n access to your Google Calendar and click Continue.


What Can You Do With Google Calendar Connected to n8n?

Once the connection is established, Google Calendar becomes part of your n8n automation ecosystem. Here's what becomes possible.

Automate Workflows Based on Calendar Events

  • The five Google Calendar trigger types in n8n let you build workflows that activate automatically whenever your schedule changes. When a new event is created, n8n can automatically send confirmation emails to attendees via Gmail, create matching tasks in Notion or Trello, or post alerts to your Slack channel. When an event starts, n8n can send SMS reminders, open related documents, or launch a meeting bot. When an event ends, n8n can automatically save summary notes, update project statuses, or send feedback surveys to participants.

Manage and Sync Calendar Data Across Systems

  • Using the Actions group, n8n can actively read, create, update, or delete calendar events based on data from other applications. For instance, when a new order arrives from WooCommerce, n8n automatically creates a shipping event on your calendar. When a customer books through a Typeform form, n8n instantly creates the corresponding appointment and sends Google Meet links to both parties. Everything runs hands-free on your end.

Important Considerations Before Going Live

  • If you're running n8n on localhost instead of a real domain, Google OAuth won't permit authentication in production. For actual work, you'll need to deploy n8n on a server with a valid HTTPS address and update the Authorized redirect URI in Google Cloud accordingly. The real concern is that apps in Testing mode only support up to 100 test users, and tokens expire after 7 days. If you want stable long-term usage, plan to submit your app for Google verification.

5 Best AI Coding Subscriptions for 2026: Finding Value Beyond 'Unlimited' Plans

On

AI-powered coding tools are advancing at breakneck speed. In just a few years, they've evolved from novelty experiments into genuine productivity multipliers—helping developers write code faster, squash bugs quicker, refactor intelligently, and analyze projects with minimal friction.

There's a shift happening in how these platforms charge. Previously, many AI coding services lured users with "unlimited" packages. Pay a flat monthly fee, get nearly unrestricted access. Simple. Appealing. Unsustainable.

The reality is brutal: running cutting-edge AI models costs serious money. So providers are moving away from unlimited tiers toward token limits, credit systems, weekly caps, and hourly restrictions. Users still pay monthly subscriptions, but with explicit controls over how much they can actually consume. What's interesting here is that this isn't necessarily bad news. When designed thoughtfully, token and credit-based plans give developers better cost predictability and eliminate the false "unlimited" facade that actually tanks your speed or locks features when you cross some invisible threshold.

Below are five AI coding subscriptions that deliver genuine value right now—each suited to different workflows and development needs.

MiniMax Token Plan

MiniMax stands out for developers hunting for low-cost AI with reasonable limits. Around 20 USD per month buys access to MiniMax's coding models through web and desktop apps, plus integration with familiar tools: Claude Code, Cursor, Cline, Roo Code, Kilo Code, Codex CLI, and OpenCode.

Instead of hourly or weekly caps, MiniMax uses token-based metering. You control allocation directly. Prefer pay-as-you-go? Credit packs start at just $5. For coding, debugging, refactoring, or building AI agents, the cost-to-output ratio here is genuinely competitive.

MiMo Token Plan

MiMo is newer but gaining serious traction in developer circles. Fast processing speed, efficient token consumption, and genuinely impressive UI generation capabilities set it apart.

Like MiniMax, you subscribe monthly and receive credits usable across MiMo's AI model ecosystem. The real concern is whether the speed gains justify the cost—but for large projects, they often do.

Xiaomi's MiMo-V2.5-Pro supports context windows up to 1 million tokens, ideal for large codebases or tasks requiring the AI to retain massive amounts of code context. It integrates with OpenCode, Cline, OpenClaw, Kilo Code, and Blackbox—perfect if you're building custom workflows or deploying AI agents.

GLM Coding Plan

GLM Coding Plan used to own the "cheapest AI coding option" title. Lately, Z.ai adjusted pricing—likely to offset operating costs for their newer GLM-5.2 model and shore up tool integrations.

It's no longer the bargain basement pick, but it remains solid for developers wanting a dedicated coding assistant rather than a general-purpose chatbot. Supports Claude Code, Cline, Kilo Code, OpenCode, and OpenClaw. Focus is practical: writing, debugging, building features.

OpenAI Codex

If you're on ChatGPT already, OpenAI's Codex extension for Visual Studio Code is the path of least resistance. It integrates directly into the ChatGPT ecosystem—no separate AI coding subscription needed.

Codex understands your entire project structure. It generates code, fixes bugs, analyzes codebases, and modifies multiple files simultaneously. The catch? Daily or weekly usage limits apply. Heavy-duty developers burn through these fast. You can buy additional credits to keep going, but costs add up.

If you're already on ChatGPT Plus or higher, Codex deserves a trial run before exploring alternatives.

Kimi Code

Kimi Code skips token counting in favor of weekly quota resets. Track your weekly allowance, not cumulative token spend. Simpler mental model.

Works on web, Visual Studio Code, CLI, and developer-focused tools. The AI handles codebase analysis, file edits, terminal commands, refactoring, debugging, and feature development. Their Kimi K2.7 Code model has noticeably improved coding quality, making it a solid pick for Kimi ecosystem regulars.

Which AI Coding Plan Should You Choose?

There's no universal best. Your pick depends on tools you already use and daily workload intensity.

ChatGPT Plus users: Start with OpenAI Codex. It's pre-integrated, runs smoothly in VS Code, and understands projects well.

Need a backup service or plan to build AI agents? MiniMax Token Plan wins on budget and generous limits. GLM Coding Plan fits if you want a specialized ecosystem.

Large codebases or exploring different workflows? MiMo Token Plan impresses with speed and 1-million-token support.

Heavy Kimi users? Kimi Code balances weekly resets with solid real-world coding support.

The industry trend is clear: AI coding providers are abandoning "unlimited" theater in favor of transparent, resource-aware subscriptions. This helps you control costs while letting developers fund better, stronger models. Everyone wins.

n8n tutorial - Lesson 27: Connect n8n to Telegram via Cloudflare Tunnel

On
n8n tutorial - Lesson 27: Connect n8n to Telegram via Cloudflare Tunnel

Hi everyone, in this post we'll walk through how to connect n8n to Telegram using a Cloudflare Tunnel — making your n8n telegram chatbot reachable from the internet without a VPS. This is part of the n8n Workflow Automation Tutorial series and covers the exact setup used to activate the T7-B2-Telegram-Chatbot workflow in a real session.

How to do:

Step 1 — Install Cloudflare Tunnel (cloudflared)

You need cloudflared installed locally to create a public tunnel to your n8n instance running on localhost:5678.
  1. Open a terminal and run: winget install Cloudflare.cloudflared
  2. After installation, start a quick tunnel with: cloudflared tunnel --url http://localhost:5678
  3. Copy the generated public URL — it looks like https://random-name.trycloudflare.com. You will need this in the next step.

Note — This is a "quick tunnel." The URL changes every time you restart cloudflared. That means you must update WEBHOOK_URL and restart n8n each time. A Named Tunnel fixes this — covered at the end of this post.

Step 2 — Set WEBHOOK_URL in Docker Compose

n8n needs to know its own public URL so it can register the correct webhook address with Telegram.
  1. Open your docker-compose.yml file in a text editor.
  2. Under the environment section for your n8n service, add or update:
    • WEBHOOK_URL=https://your-tunnel-url.trycloudflare.com
  3. Save the file, then restart n8n by running: docker compose down && docker compose up -d

Tip — If you skip this step, n8n will still register a localhost address with Telegram, and the webhook will never receive messages. Always set WEBHOOK_URL before activating any Telegram workflow.

Step 3 — Build the Telegram Chatbot Workflow (T7-B2-Telegram-Chatbot)

This workflow receives a user message from Telegram, passes it to an AI Agent, and sends the reply back — the core n8n telegram chatbot pattern.
  1. In n8n, create a new workflow named T7-B2-Telegram-Chatbot.
  2. Add a Telegram Trigger node as the starting node. This registers a webhook with Telegram automatically when the workflow is activated.
  3. Add an AI Agent node (using Claude Haiku 4.5 or your preferred model) connected to the Telegram Trigger.
  4. In the AI Agent node, set Source for Prompt to Define below, then set the prompt expression to: {{ $json.message.text }}
    • This extracts the actual text the user typed in Telegram.
  5. Do not add a Simple Memory node — Telegram Trigger uses a session concept, but Simple Memory caused issues in testing and was removed.
  6. Add a Telegram node at the end to send the AI Agent's reply back to the user.

Tip — The prompt expression {{ $json.message.text }} is the correct path for Telegram Trigger output. If you use a generic {{ $json.text }} it will return empty and the agent will have no input to work with.

Step 4 — Activate the Workflow

Activating the workflow registers the webhook URL with Telegram — this is the step that makes everything live.
  1. Make sure cloudflared is still running and your n8n instance is up with the correct WEBHOOK_URL set.
  2. In the workflow editor, click the Inactive toggle in the top-right corner to set the workflow to Active.
  3. n8n will call the Telegram API to register the webhook at your Cloudflare Tunnel URL automatically.
  4. Open Telegram, find your bot, send a message, and verify the AI Agent replies.

Note — Every time the Cloudflare quick tunnel restarts and gives you a new URL, you must: update WEBHOOK_URL in docker-compose.yml, restart n8n, then toggle the workflow Inactive → Active again. This re-registers the new URL with Telegram.

Step 5 — Understand the Quick Tunnel Limitation and Next Steps

The quick tunnel works perfectly for testing your n8n workflow automation, but it has one real-world drawback you need to plan around.
  1. The problem: The quick tunnel URL (e.g. https://random-name.trycloudflare.com) changes on every restart of cloudflared.
  2. Each URL change requires three actions:
    • Update WEBHOOK_URL in docker-compose.yml
    • Restart n8n with docker compose down && docker compose up -d
    • Toggle the Telegram workflow Inactive then Active to re-register the webhook
  3. Long-term fix — Named Cloudflare Tunnel: A named tunnel gives you a fixed subdomain (e.g. https://n8n.yourdomain.com) that never changes. Setup requires a Cloudflare account with a domain attached.
  4. Alternative — VPS deployment: When you deploy n8n on a VPS, the Webhook node automatically gets a public URL. You no longer need cloudflared at all.
    • Note: Oracle Cloud free tier signup from some regions (e.g., Vietnam) can be difficult — factor this into your planning.

Production tip — For a stable n8n telegram chatbot in production, a Named Cloudflare Tunnel or a VPS is strongly recommended. The quick tunnel is only suitable for development and testing sessions.

Key Lessons from This Session

  1. Always set WEBHOOK_URL before activating a Telegram workflow. Without it, n8n registers a localhost address that Telegram cannot reach.
  2. Quick Cloudflare Tunnel URLs are temporary. The URL changes on every restart — you must update WEBHOOK_URL, restart n8n, and re-activate the workflow each time.
  3. Use {{ $json.message.text }} for the AI Agent prompt in a Telegram Trigger workflow. This is the correct data path from the Telegram Trigger output.
  4. Remove Simple Memory when using a Telegram Trigger. Simple Memory added complexity without benefit in this setup and caused issues during testing.
  5. The Webhook node in n8n does not create a public URL by itself. It only creates an endpoint — you still need cloudflared, ngrok, or a VPS to expose it publicly. On a VPS, the public URL is automatic.
  6. Named Cloudflare Tunnel or VPS is the correct production path. The quick tunnel is a development shortcut, not a stable deployment strategy.

Conclusion:

In this n8n tutorial, we connected a local n8n instance to Telegram using a Cloudflare Tunnel, activated the T7-B2-Telegram-Chatbot workflow, and got a real AI-powered chatbot responding to Telegram messages. The key takeaway for this n8n workflow automation pattern is that WEBHOOK_URL and tunnel stability are the two variables that determine whether your bot stays online. In the next post in this series, we'll merge the Telegram Chatbot with a RAG pipeline so the bot can answer questions from a knowledge base.

Getting Started with Mapify AI: Turn Any Content Into Mind Maps in Minutes

On

Mapify is an AI-powered tool that does something pretty clever: it transforms lengthy content into visual mind maps in just a few minutes. Instead of manually reading, analyzing, and organizing ideas yourself, you simply feed Mapify your text, documents, website links, or YouTube videos—and it automatically identifies key points and builds a structured, easy-to-follow mind map for you.

What's interesting here is how Mapify handles content summarization. The tool excels at extracting the most important information and presenting it as logical branches, making it ideal for students and professionals who need to absorb knowledge quickly. Beyond just auto-generating mind maps, Mapify lets you edit branches, add new information, and reorganize the structure however you like. Here's how to get started.

How to Create Mind Maps with Mapify

Step 1:

Head to the Mapify website using the link below and set up your account.

https://mapify.so/vi/app/new

n8n tutorial - Lesson 26: n8n Multi-Tool AI Chatbot: Internal Knowledge Assistant

On
n8n tutorial - Lesson 26: n8n Multi-Tool AI Chatbot: Internal Knowledge Assistant

Hi everyone, in this session we're building a multi-tool internal knowledge assistant using an n8n chatbot workflow — an AI agent that pulls data from multiple Google Sheets sources and synthesizes it into a single natural-language report. This is part of our ongoing n8n workflow automation tutorial series, and it's where the real power of agents over fixed workflows becomes clear.

How to do:

Step 1 — Upgrade Your Existing Agent with Three New Tools

Open your base agent workflow (here: T7-B1-First-Agent) and add three new Google Sheets tool nodes — each connecting to a different data source.
  1. Open the workflow and click the + button inside the AI Agent node's Tools section to add a new tool.
  2. Add the first tool: set Name to get_rejected_content, connect it to the Google Sheets node pointing to spreadsheet T6-Rejected, tab Sheet1.
  3. Add the second tool: set Name to get_youtube_performance, connect it to spreadsheet T5-Performance-Snapshots, tab Snapshots.
  4. Add the third tool: set Name to get_comments_queue, connect it to spreadsheet T5-Comments-Queue, tab Queue.
  5. For each tool, fill in the Description field immediately — describe what data it returns so the agent can decide when to call it.

Note — Always configure all four fields — Name, Description, Operation, and Document/Sheet — in one go. Skipping Description means the agent won't know when to invoke the tool, and you'll have to go back and re-edit each node.

Step 2 — Add a System Prompt to Define the Agent's Role

The System Message field in the AI Agent node is where you define the agent's persona, default language, and response behavior — without it, the agent gives raw data dumps instead of useful summaries.
  1. Click the AI Agent node to open its settings, then locate the System Message field.
  2. Write a prompt that:
    • Declares the agent's role (e.g., "You are an internal assistant for a content team.")
    • Specifies the response language appropriate for your team.
    • Instructs the agent to summarize insights rather than list raw data.
  3. Save the node after entering the system prompt.

Tip — The system prompt is the single biggest lever for output quality. Telling the agent to "summarize insights, not raw rows" transforms the response from a data table into an actionable briefing.

Step 3 — Test the Daily Briefing (Multi-Tool Parallel Call)

Send one natural-language question to verify the agent calls all three tools and synthesizes a combined report.
  1. Open the workflow's test chat or trigger a manual execution.
  2. Send the message: Give me a full system overview report for today.
  3. Watch the execution log — the agent should call all three tools in parallel: get_rejected_content, get_youtube_performance, and get_comments_queue.
  4. Verify the output contains all four sections:
    • YouTube performance summary
    • Blog/rejected content status
    • Comment queue overview
    • A "needs action" section highlighting items requiring follow-up

Note — This is the core advantage of an agent over a fixed n8n workflow automation: one free-form question triggers dynamic multi-tool reasoning. A scheduled workflow would require you to hardcode exactly which nodes run and in what order.

Step 4 — Build the Telegram Chatbot Workflow

Create a new workflow named T7-B2-Telegram-Chatbot that chains a Telegram trigger, the AI agent, and a Telegram reply node.
  1. Create a new workflow and add a Telegram Trigger node as the entry point — this listens for incoming messages via webhook.
  2. Add an AI Agent node and configure it with the same four tools and system prompt from Steps 1–2.
  3. Add a Simple Memory node and connect it to the AI Agent's memory input so conversation context persists across messages.
  4. Add a Telegram node (Send Message operation) and wire it to the agent's output to return the response to the user.
  5. Set the model to Claude Haiku 4.5 (or your preferred model) in the AI Agent node.

Step 5 — Handle the Localhost / HTTPS Limitation for Telegram

Telegram Trigger uses a webhook, which requires a publicly accessible HTTPS URL — this is the wall you'll hit when running n8n locally.
  1. Understand the constraint:
    • Telegram webhooks only POST to HTTPS public URLs.
    • A local localhost n8n instance has no public URL, so Telegram can't reach it.
  2. Attempt with ngrok (common workaround):
    • Install ngrok and get an HTTPS tunnel URL.
    • Open docker-compose.yml and add the environment variable N8N_WEBHOOK_URL=https://your-ngrok-url.
    • Restart the container: run docker-compose down && docker-compose up -d.
    • Verify the variable was applied: run docker exec <container_name> env | findstr N8N_WEBHOOK_URL.
  3. Accept the result: ngrok free tier is too unstable for Telegram webhooks in practice — tunnels disconnect, Telegram stops receiving events.
  4. Leave T7-B2-Telegram-Chatbot as Inactive until you deploy to a VPS with a real domain and HTTPS certificate.

Production tip — The real fix is deploying n8n on a VPS with a proper domain and HTTPS — the same requirement as Human-in-the-Loop workflows. ngrok is fine for quick testing but not reliable for any trigger that depends on an external service pushing data to you.

Note — When working with Docker, remember that the container name shown by docker ps is not always the same as the service name in docker-compose.yml. Always use docker ps to find the real container name before running docker exec commands.

Step 6 — Audit API Costs and Decide Which Workflows to Keep Active

Some scheduled workflows call an AI model on every item every run — these accumulate cost fast and should be deactivated when not needed.
  1. Identify high-cost workflows to deactivate:
    • T5-B2-Comment-Pipeline — runs every 30 minutes, calls Claude for every comment. Primary cost driver.
    • T2-B4-Email-Classifier — runs every 15 minutes, calls Claude for every email.
  2. Identify safe workflows to keep active (no AI calls or infrequent calls):
    • T6-B1-Error-Handler — no AI node.
    • T5-B2b-Reply-Sender — no AI node.
    • T5-B3b-Title-Updater — no AI node.
    • T5-B4-Performance-Insight — weekly schedule, one AI call per run.
    • T5-B7-Weekly-Digest — weekly schedule, one AI call per run.
  3. Toggle the high-cost workflows to Inactive in the n8n dashboard until you're ready to run them intentionally.

Tip — A per-item AI call inside a frequent schedule is the fastest way to drain API credits. The rule: if a workflow calls an AI model in a loop and runs more than once per hour, treat it as high-cost by default and run it manually or reduce its frequency.

Key Lessons from This Session

  1. Always fill in the tool Description field immediately. The agent uses this text to decide which tool to call — a blank description makes the tool invisible to the agent's reasoning.
  2. One question → multi-tool parallel execution is the agent's core value. A fixed n8n tutorial workflow can automate a known sequence; an agent handles unknown, flexible queries by choosing tools dynamically.
  3. Telegram Trigger requires a real HTTPS public URL. ngrok free tier is not reliable enough for production webhooks — deploy to a VPS for any external trigger.
  4. Set environment variables in docker-compose.yml, not in the running container. Use docker-compose down && docker-compose up -d to apply changes, and verify with docker exec.
  5. Frequent scheduled workflows with per-item AI calls are the main API cost risk. Audit and deactivate them when not in active use.
  6. Agent vs. fixed workflow is a design choice, not a default. Use agents when the query is unpredictable or requires reasoning; use fixed workflows for known, repeatable automation sequences.

Conclusion:

In this n8n tutorial session, we turned a single-tool agent into a full internal knowledge assistant by connecting it to three Google Sheets data sources, adding a system prompt, and validating multi-tool parallel execution with one natural-language question. We also built a Telegram-connected n8n chatbot workflow, hit the real-world HTTPS limitation of local deployments, and learned how to audit API costs across the entire automation stack. The next session will explore either scheduled agent automation, custom code tools, or a VPS deployment to unlock Telegram and Human-in-the-Loop workflows — all key milestones in n8n workflow automation.
