How to delete queue updates in telegram api?

Question

I'm trying to delete messages from /getUpdates in telegram API but I didn't know how.. I tried to use /deleteMessage

https://api.telegram.org/bot<TOKEN>/deleteMessage?chat_id=blahblah&message_id=BlahBlah

But it didn't delete message from API database..

TL;DR: Call getUpdates() with the offset parameter set to the last message's id, incremented by 1

We'll need to let Telegram know which message's we've processed. To do this, set the offset parameter to the update_id + 1 of the last message your script has processed.

1. Call getUpdates() to get the update_id of the latest message

   https://api.telegram.org/<MY-TOKEN>/getUpdates
   

   {
       "ok": true,
           "result": [
               {
                   "update_id": 343126593,   # <-- Remember / Save this id
                   "message": {
                   ...
   

2. Increment the update_id by 1

3. On the next getUpdates() call, set the offset parameter to the id:

   https://api.telegram.org/<MY-TOKEN>/getUpdates?offset=343126594

To delete all messages find update id of last message of the queue..

here "836737487", so run on browser

"https://api.telegram.org/bot<token>/getupdates?offset=836737488"

[note: offset integer value will be higher than update_id of last message]

and if you want to delete specific message then set offset value as update_id of the next message of that specific message
