Golang bindings for the Telegram Bot API

All methods are fairly self explanatory, and reading the godoc page should explain everything. If something isn't clear, open an issue or submit a pull request.

The scope of this project is just to provide a wrapper around the API without any additional features. There are other projects for creating something with plugins and command handlers without having to design all that yourself.

Example

First, ensure the library is installed and up to date by running go get -u github.com/go-telegram-bot-api/telegram-bot-api.

This is a very simple bot that just displays any gotten updates, then replies it to that chat.

package main

import (
	"log"

	"github.com/go-telegram-bot-api/telegram-bot-api"
)

func main() {
	bot, err := tgbotapi.NewBotAPI("MyAwesomeBotToken")
	if err != nil {
		log.Panic(err)
	}

	bot.Debug = true

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

	u := tgbotapi.NewUpdate(0)
	u.Timeout = 60

	updates, err := bot.GetUpdatesChan(u)

	for update := range updates {
		if update.Message == nil { // ignore any non-Message Updates
			continue
		}

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

		msg := tgbotapi.NewMessage(update.Message.Chat.ID, update.Message.Text)
		msg.ReplyToMessageID = update.Message.MessageID

		bot.Send(msg)
	}
}

There are more examples on the site with detailed information on how to do many different kinds of things. It's a great place to get started on using keyboards, commands, or other kinds of reply markup.
