How do I set up a webhook for my Telegram bot using this package?

Refer to the separate WEBHOOK.md file for detailed steps, including handling self-signed certificates and reverse proxies like NGINX. It's complex and may require additional server configuration for production use.

node-red-contrib-telegrambot vs telegraf.js for Telegram bots

If you're already using Node-RED for automation, this package saves time with visual programming. For code-centric development or more control, telegraf.js is better suited as a standalone library.

How to handle media files like photos and videos in my bot?

The receiver node can automatically download media to a specified directory, with file IDs in msg.payload and optional weblinks. The sender node supports sending media via file IDs or paths, as shown in the message types table.

Can I use this for Telegram payment bots?

Yes, it supports invoice and successful_payment message types, with examples in the credits for payment functions. You need to configure provider tokens and handle pre-checkout queries via event nodes.

What's the difference between polling and webhook modes?

Polling is simpler but less efficient, checking for updates every 300ms by default. Webhook is real-time but requires HTTPS setup. The config node lets you switch between them based on your needs.

How to implement inline keyboards with callback queries?

Use the event node set to callback_query, and define inline_keyboard in msg.payload.options when sending messages. The package includes example flows for basic and editable inline keyboards.

What is telegrambot?

node-red-contrib-telegrambot is a Node-RED package that provides nodes for building and managing Telegram bots. It allows users to visually create bots that can send and receive messages, handle commands, and respond to events using the Telegram Bot API. The package solves the problem of integrating Telegram functionality into Node-RED flows without writing low-level API code.

Target Audience

Node-RED users, IoT developers, and hobbyists who want to create Telegram bots for notifications, automation, or interactive applications within a visual programming environment.

Value Proposition

Developers choose this package because it offers a drag-and-drop interface for Telegram bot development, comprehensive support for Telegram API features, and seamless integration with Node-RED's ecosystem for automation and IoT projects.

Overview

Telegram bot nodes for node-red.

Use Cases

Best For

Creating notification bots for IoT devices in Node-RED
Building interactive chatbots with custom keyboards
Automating responses to Telegram commands in workflows
Developing bots that handle media messages and files
Implementing payment or invoice bots using Telegram's API
Setting up bots that use webhooks for real-time updates

Not Ideal For

Projects requiring standalone bot deployment without Node-RED infrastructure
Teams needing ultra-low latency responses where visual flow execution adds overhead
Developers who prefer code-first approaches with direct Telegram API libraries like telegraf.js
Applications integrating multiple messaging platforms beyond Telegram

Pros & Cons

Pros

Comprehensive API Coverage

Supports all major Telegram message types, events, and API commands, including media groups, payments, and inline queries, as detailed in extensive tables for sender and receiver nodes.

Visual Development Ease

Integrates seamlessly into Node-RED's drag-and-drop interface, enabling bot logic creation without coding, with example flows for echo, keyboards, and commands.

Flexible Update Modes

Offers polling, webhook, or no-update modes with configurable intervals and SOCKS proxy support, adapting to different network and deployment scenarios.

Active Community Support

Credits numerous contributors, has a Telegram chat for help, and regular updates, ensuring ongoing maintenance and feature enhancements.

Cons

Complex Webhook Setup

Webhook configuration requires handling HTTPS certificates and reverse proxies, with separate documentation (WEBHOOK.md) that can be challenging for non-experts.

Node-RED Dependency

Tied exclusively to Node-RED, creating vendor lock-in and limiting portability to other bot frameworks or standalone applications.

Token Management Limits

The README warns against using a token in multiple configuration nodes simultaneously, which can hinder scalability for complex, multi-instance bot deployments.
