# Telegram Bot API

The Telegram Bot API provides an HTTP API for creating Telegram Bots.

If you've got any questions about bots or would like to report an issue with your bot, kindly contact us at @BotSupport in Telegram.

Please note that only global Bot API issues that affect all bots are suitable for this repository.

To learn how to use it, please see our [examples](https://github.com/raminsa/telegram-bot-api/tree/main/examples).

Bot API 7.7 recent changes [July 7, 2024](https://core.telegram.org/bots/api#july-7-2024).

## Example

use get update method (simple):
```go
package main

import (
"fmt"
"log"

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

func main() {
tg, err := telegram.New("BotToken")
if err != nil {
log.Fatal(err)
}

getUpdates := tg.NewGetUpdates()
getUpdates.Offset = 1
getUpdates.Timeout = 60
getUpdates.Limit = 100
updates := tg.GetUpdatesChan(getUpdates)
for update := range updates {
fmt.Println(update.UpdateID, getUpdates.Offset)
if update.UpdateID >= getUpdates.Offset {
getUpdates.Offset = update.UpdateID + 1
}
if update.Message != nil {
fmt.Println(update.Message.Text)
}
}
}
```

use webhook method (http):
```go
package main

import (
"fmt"
"log"
"net/http"

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

func main() {
fmt.Println("start at port:", "BotPortNumber")
err := http.ListenAndServe("BotPortNumber", http.HandlerFunc(handleWebhook))
if err != nil {
log.Fatal(err)
}
}

func handleWebhook(w http.ResponseWriter, r *http.Request) {
update, err := telegram.HandleUpdate(r)
if err != nil {
err = telegram.HandleUpdateError(w, err)
if err != nil {
//handle err
}
return
}

if update.Message != nil {
fmt.Println(update.Message.Text)
}
}
```

use webhook method (https):
```go
package main

import (
"fmt"
"log"
"net/http"

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

func main() {
fmt.Println("start at port:", "BotPortNumber")
err := http.ListenAndServeTLS("BotPortNumber", "BotCertFile", "BotKeyFile", http.HandlerFunc(handleWebhook))
if err != nil {
log.Fatal(err)
}
}

func handleWebhook(w http.ResponseWriter, r *http.Request) {
update, err := telegram.HandleUpdate(r)
if err != nil {
err := telegram.HandleUpdateError(w, err)
if err != nil {
//handle err
}
return
}

if update.Message != nil {
fmt.Println(update.Message.Text)
}
}
```

to generate your cert file use this. See [self-signed](https://core.telegram.org/bots/self-signed) guide for details.:

openssl req -newkey rsa:2048 -sha256 -nodes -keyout -x509 -days 36500 -out -subj "/C=US/ST=New York/L=Brooklyn/O=Example Brooklyn Company/CN="

use a channel to handle all requests (Avoid ReadTimeoutExpired error), http.ListenAndServe() supports concurrency:
```go
package main

import (
"fmt"
"net/http"

"github.com/raminsa/telegram-bot-api/telegram"
"github.com/raminsa/telegram-bot-api/types"
)

func main() {
fmt.Println("start at port:", "BotPortNumber")
updates := listenForWebhook(100)
go http.ListenAndServeTLS("BotPortNumber", "BotCertFile", "BotKeyFile", nil)
for update := range updates {
if update.Message != nil {
fmt.Println(update.Message.Text)
}
}
}

func listenForWebhook(maxWebhookConnections int) types.UpdatesChannel {
ch := make(chan types.Update, maxWebhookConnections)
http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
if update, err := telegram.HandleUpdate(r); err != nil {
return
} else {
ch <- *update
}
})

return ch
}
```


## Custom Client
use client with custom options:
```go
package main

import (
"fmt"
"log"

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

func main() {
client := telegram.Client()
client.BaseUrl = "baseUrl"
client.Proxy = "proxy"
client.ForceV4 = true
client.DisableSSLVerify = true
client.ForceAttemptHTTP2 = true
tg, err := telegram.NewWithCustomClient("BotToken", client)
if err != nil {
log.Fatal(err)
}

me, err := tg.GetMe()
if err != nil {
log.Fatal(err)
}

fmt.Println("botID:", me.ID, "botUsername:", me.UserName)
}
```


## Debug

use debug option and write to local file:
```go
package main

import (
"fmt"
"log"

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

func main() {
tg, err := telegram.NewWithBaseUrl("BotToken", "baseUrl")
if err != nil {
log.Fatal(err)
}

//active debug mode
tg.Bot.Debug = true

me, err := tg.GetMe()
if err != nil {
log.Fatal(err)
}

fmt.Println("botID:", me.ID, "botUsername:", me.UserName)

//access debug log
//method 1: write to console
fmt.Println(tg.GetLoggerFile())

//method 2: write to file
err = tg.WriteLoggerFile("fileName")
if err != nil {
log.Fatal(err)
}
}
```
