Golang Bindings for the Telegram Bot API

Headline

This is a maintained fork of go-telegram-bot-api that preserves the original design while staying current with the latest Telegram Bot API specifications. It continues the development of the original github.com/go-telegram-bot-api package.

Features

Complete coverage of the Telegram Bot API
Simple and intuitive interface
Minimal dependencies
Production-ready and actively maintained
Preserves original API structure for easy migration

Installation

Install the latest version:

go get -u github.com/OvyFlash/telegram-bot-api

❗ Tag versioning is discouraged due to the unstable nature of the Telegram Bot API, and it might break at any time after the API changes. ~~go get -u github.com/OvyFlash/telegram-bot-api/v7~~

Quick Start

Here's a simple echo bot using polling:

package main

import (
    "log"
    "time"
    api "github.com/OvyFlash/telegram-bot-api"
)

func main() {
    bot, err := api.NewBotAPI("BOT_TOKEN")
    if err != nil {
        panic(err)
    }

    log.Printf("Authorized on account %s", bot.Self.UserName)

    updateConfig := api.NewUpdate(0)
    updateConfig.Timeout = 60
    updatesChannel := bot.GetUpdatesChan(updateConfig)

    // Optional: Clear initial updates
    time.Sleep(time.Millisecond * 500)
    updatesChannel.Clear()

    for update := range updatesChannel {
        if update.Message == nil {
            continue
        }

        log.Printf("[%s] %s", update.Message.From.UserName, update.Message.Text)

        msg := api.NewMessage(update.Message.Chat.ID, update.Message.Text)
        msg.ReplyParameters.MessageID = update.Message.MessageID

        bot.Send(msg)
    }
}

Webhook Setup

For webhook implementation:

Check the examples folder for examples of webhook implementations
Use HTTPS (required by Telegram)
- Generate SSL certificate:
```
openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days 3560 -subj "//O=Org\CN=Test" -nodes
```
- Bring your own SSL certificate. Let's Encrypt is recommended for free TLS certificates in production.
