Why does my n8n Telegram trigger not work?

Telegram needs a public HTTPS webhook with a valid certificate. Check WEBHOOK_URL, DNS, HTTPS and that the workflow is active.

Can n8n send WhatsApp messages?

Yes, through the WhatsApp Business Cloud API from Meta, which needs a business account and approved templates.

Can I run Telegram bots from n8n on my own server?

Yes. Host n8n on a VPS with HTTPS and use the Telegram Trigger and Telegram nodes.

n8n Telegram and WhatsApp Automation: A Practical Guide

Telegram and WhatsApp are popular channels for alerts, support and simple chatbots. n8n has nodes for both. The hard part on a self-hosted server is usually not the workflow, it is getting a public HTTPS webhook URL working.

What you need first

n8n running on a server with a domain and a valid HTTPS certificate.
WEBHOOK_URL set to your public address. See the environment variables guide.
An active workflow, because the production webhook only listens when active.

Telegram: step by step

Open Telegram and talk to @BotFather. Create a bot and copy the token.
In n8n, add a Telegram credential with that token.
Add the Telegram Trigger node and choose the updates you want, such as messages.
Add nodes that process the message and a Telegram node to reply.
Activate the workflow. n8n registers the webhook with Telegram.

Telegram only sends events to HTTPS URLs with a valid certificate, so if nothing arrives, check HTTPS, DNS and WEBHOOK_URL. Our webhook troubleshooting guide lists the common causes.

Telegram ideas

Server or website down alerts.
New order or payment notifications.
A command bot that returns report numbers.
Daily summary messages for a team group.

WhatsApp: what is different

WhatsApp automation normally uses the official WhatsApp Business Platform (Cloud API) from Meta. You need a Meta business account, a phone number set up for the API and approved message templates for messages that start a conversation. In n8n you use the WhatsApp Business Cloud nodes and a webhook that Meta calls with incoming messages. Rules and pricing are set by Meta and can change, so read their current documentation.

WhatsApp ideas

Order confirmations and shipping updates.
Appointment reminders.
Replies to common questions, with a handoff to a person for hard ones.
Lead capture from a click-to-chat link.

Good practice

Only message people who agreed to hear from you.
Follow each platform's rules. Spam gets numbers banned.
Verify webhook signatures where the platform supports it.
Keep tokens in n8n credentials, not in workflow text.
Run the workflow on a server so it answers 24/7.

A managed n8n server comes with HTTPS and a stable address for Telegram and WhatsApp webhooks.
