If you need to publish your bot on AWS Lambda(or something like it) and AWS API Gateway,
you can use such example:
In this code used AWS Lambda Go net/http server adapter [algnhsa](https://github.com/akrylysov/algnhsa)
```go
package main
import (
"github.com/akrylysov/algnhsa"
"github.com/go-telegram-bot-api/telegram-bot-api"
"log"
"net/http"
)
func answer(w http.ResponseWriter, r *http.Request) {
bot, err := tgbotapi.NewBotAPI("MyAwesomeBotToken")
if err != nil {
log.Fatal(err)
}
bot.Debug = true
updates := bot.ListenForWebhookRespReqFormat(w, r)
for update := range updates {
if update.Message == nil {
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
_, err := bot.Send(msg)
if err != nil {
log.Printf("Error send message: %s | Error: %s", msg.Text, err.Error())
}
}
}
func setWebhook(_ http.ResponseWriter, _ *http.Request) {
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.NewWebhook("https://your_api_gateway_address.com/"+bot.Token))
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)
}
}
func main() {
http.HandleFunc("/set_webhook", setWebhook)
http.HandleFunc("/MyAwesomeBotToken", answer)
algnhsa.ListenAndServe(http.DefaultServeMux, nil)
}
```
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
