README
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.
Join the development group if you want to ask questions or discuss development.
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 wiki 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.
If you need to use webhooks (if you wish to run on Google App Engine), you may use a slightly different method.
package main
import (
"log"
"net/http"
"github.com/go-telegram-bot-api/telegram-bot-api"
)
func main() {
bot, err := tgbotapi.NewBotAPI("MyAwesomeBotToken")
if err != nil {
log.Fatal(err)
}
bot.Debug = true
log.Printf("Authorized on account %s", bot.Self.UserName)
_, err = bot.SetWebhook(tgbotapi.NewWebhookWithCert("https://www.google.com:8443/"+bot.Token, "cert.pem"))
if err != nil {
log.Fatal(err)
}
info, err := bot.GetWebhookInfo()
if err != nil {
log.Fatal(err)
}
if info.LastErrorDate != 0 {
log.Printf("Telegram callback failed: %s", info.LastErrorMessage)
}
updates := bot.ListenForWebhook("/" + bot.Token)
go http.ListenAndServeTLS("0.0.0.0:8443", "cert.pem", "key.pem", nil)
for update := range updates {
log.Printf("%+v\n", update)
}
}
If you need, you may generate a self signed certficate, as this requires HTTPS / TLS. The above example tells Telegram that this is your certificate and that it should be trusted, even though it is not properly signed.
openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days 3560 -subj "//O=Org\CN=Test" -nodes
Now that Let's Encrypt is available, you may wish to generate your free TLS certificate there.
