Clear "pending_update_count" in Telegram Bot

Question

I want to clear all pending_update_count in my bot!

The output of below command :

https://api.telegram.org/botxxxxxxxxxxxxxxxx/getWebhookInfo

Obviously I replaced the real API token with xxx

is this :

{
 "ok":true,"result":
    {
     "url":"",
     "has_custom_certificate":false,
     "pending_update_count":5154
    }
}

As you can see, I have 5154 unread updates til now!! ( I'm pretty sure this pending updates are errors! Because no one uses this Bot! It's just a test Bot)

By the way, this pending_update_count number are increasing so fast! Now that I'm writing this post the number increased 51 and reached to 5205 !

I just want to clear this pending updates. I'm pretty sure this Bot have been stuck in an infinite loop!

Is there any way to get rid of it?

P.S:

I also cleared the webhook url. But nothing changed!

UPDATE:

The output of getWebhookInfo is this :

{
   "ok":true,
   "result":{
      "url":"https://somewhere.com/telegram/webhook",
      "has_custom_certificate":false,
      "pending_update_count":23,
      "last_error_date":1482910173,
      "last_error_message":"Wrong response from the webhook: 500 Internal Server Error",
      "max_connections":40
   }
}

Why I get Wrong response from the webhook: 500 Internal Server Error ?

Solution 1

I think you have two options:

1. set webhook that do nothing, just say 200 OK to telegram's servers. Telegram wiil send all updates to this url and the queque will be cleared.
2. disable webhook and after it get updates by using getUpdates method, after it, turn on webhook again

Update:

Problem with webhook on your side. You can try to emulate telegram's POST query on your URL. It can be something like this:

{"message_id":1,"from":{"id":1,"first_name":"FirstName","last_name":"LastName","username":"username"},"chat":{"id":1,"first_name":"FirstName","last_name":"LastName","username":"username","type":"private"},"date":1460957457,"text":"test message"}

You can send this text as a POST query body with PostMan for example, and after it try to debug your backend.

Solution 2

For anyone looking at this in 2020 and beyond, the Telegram API now supports clearing the pending messages via a drop_pending_updates parameter in both setWebhook and deleteWebhook, as per the API documentation.

Solution 3

I solved is like this

POST tg.api/bottoken/setWebhook to emtpy "url"
POST tg.api/bottoken/getUpdates
POST tg.api/bottoken/getUpdates with "offset" last update_id appeared before

doing this serveral times

POST tg.api/bottoken/getWebhookInfo

had a look if all away.

POST tg.api/bottoken/setWebhook with filled "url"

Solution 4

Just add return 1; at the end of your hook method.

Update:

Commonly this happens because of queries delay with the database.

Method 2 didnt work for me, I don't know what could i Possibly be doing wrong, as I'm getting the info using getupdates, but turning the webhook on again doesn't fix it. Method 1 I'm not sure how to implement it, is the problem setting the webhook, or where?

[Ivan]

[Ivan]

@Danil Pyatnitsev, i also facing the same problem ... can you give us simple example for method 1 ? greatly appreciate your help ...

@Ivan in your function that call by telegram, add only a line of code like return 1; and send something to bot after do.

[Ivan]

something like this ? public function index() { $content = file_get_contents("php://input"); $update = json_decode($content, true); $chatID = "12345678"; $reply = "ok"; return 1; $API_URL = "https://api.telegram.org/botTOKEN/"; $sendto =$API_URL."sendmessage?chat_id=".$chatID."&text=".$reply; file_get_contents($sendto); }

[Behnam Azimi]

@Ivan Yes! But if you just want to reset pending count do Like this: ```public function(){return 1;}

[Behnam Azimi]

@Ivan It was clear! you must! every name that you want.
