Build a Telegram Bot with n8n in 30 Minutes

Introduction to n8n and Telegram Bots

I recently discovered the power of n8n and how it can be used to automate workflows with ease. In this post, I'll share my experience of building a simple Telegram bot using n8n in under 30 minutes.

Prerequisites

Before you start, make sure you have the following:

n8n installed on your system (I'm using the desktop app)
A Telegram account and a bot token from the BotFather
Basic knowledge of n8n workflows

Step 1: Create a New Workflow

Create a new workflow in n8n and add the following nodes:

Telegram node to receive updates from your bot
Function node to process the updates
Telegram node to send responses back to the user

Step 2: Configure the Telegram Node

Configure the Telegram node to receive updates from your bot by providing the bot token and setting up a webhook. You can use the tg:// protocol to set up the webhook.

Step 3: Process Updates with a Function Node

Use the Function node to process the updates received from the Telegram node. For example, you can use JavaScript to parse the message text and respond accordingly.

Step 4: Send Responses with the Telegram Node

Configure the second Telegram node to send responses back to the user. You can use the sendMessage method to send a response.

Example Workflow

Here's an example workflow that responds with a greeting:

Receive update from Telegram node
Process update with Function node: if (msg.text === 'hello') { return { text: 'Hello! How are you?' }; }
Send response with Telegram node
