There is method for deleting messages not with bot API: core.telegram.org/method/messages.deleteMessages – Modena

Thanks @ihoru, does that mean the bot can't delete a for example incorrect post? Are you sure about that? – One

is there any solution in this regard? – One

it is not even possible other administrators to delete the message from the channel is there any solution? – One

Channel's administrator can delete message posted by bot to the channel, but not from private chat with user. – Modena

With telegram bot api v2.1 can we do this or it is still un available? – Ama

@MohammadRezaEsmaeilzadeh It's still unavailable. – Resemblance

Answer 2

There is an official support of deleteMessage method in Bot API 3.0. More details here: https://core.telegram.org/bots/api#deletemessage

https://api.telegram.org/botTOKEN/deleteMessage?chat_id=CID&message_id=MID

As you can see there are two arguments: chat_id and message_id.

You can remove bot's messages or other messages (if bot is admin) except service messages (such as join/leave messages).

1. On success, it will return following JSON object: {"ok":true,"result":true}.

2. If you are trying to remove service message or other user's message, but bot is not an admin: {"ok":false,"error_code":400,"description":"Bad Request: message can't be deleted"}.

3. If you are trying to remove non-existent message or its already deleted: {"ok":false,"error_code":400,"description":"Bad Request: message to delete not found"}

Integer messageId = callbackQuery.getMessage().getMessageId();
DeleteMessage deleteMessage = new DeleteMessage(chatId, messageId);

  execute(deleteMessage);
}catch(TelegramApiException tae) {
  throw new RuntimeException(tae);

Answer 4

you can forward message and save message id, and then remove that message. if you can do it, your message exist.

do it:

try:
   mes=bot.forward_message(chat_id=?,from_chat_id=?,message_id=?)
   bot.delete_message(chat_id=?,message_id=mes.id)
except:
   print("your message deleted")

Answer 5

There are two methods in bot api that let you to edit a message: editMessageText and editMessageCaption. It is not ideal, but you can use it as an alternative.

For example by editing the message to:

"This message is unavailable."

Answer 6

Using python, if you have a CommandHandler() you can read the chat_id and message_id like so:

dispatcher.add_handler(CommandHandler("start", handler_start))

def handler_start(update: Update, context: CallbackContext):
    chat_id = update.message.chat_id
    message_id = update.message._id_attrs[0]
    context.bot.delete_message(chat_id, message_id)

Answer 7

If on php. I send message. Get response from it (message id of bot) And use deleteMessage

<?php
$botToken = "yourBotToken";
$botAPI = "https://api.telegram.org/bot" . $botToken;

$update = json_decode(file_get_contents('php://input'), TRUE);
$msg = $update['message']['text'];
if ($msg == '/start') {
$data = http_build_query([
        'text' => "test message (delete this)",
        'chat_id' => $update['message']['chat']['id'],
]);
$send = file_get_contents($botAPI . "/sendMessage?{$data}");

$response = json_decode($send), true); // decode response
$message_id = $response['result']['message_id']; // get bots message

// Deleting message
$data_del = http_build_query([
    'chat_id' => $update['message']['chat']['id'],
    'message_id' => $message_id,
]);
    file_get_contents($botAPI . "/deleteMessage?{$data_del}");
}

https://api.telegram.org/botTOKEN/deleteMessage?chat_id=CID&message_id=MID

Example https://api.telegram.org/bot123456789:zzzzzzzzxxxxxxxxxxyyyyyyyyyy/deleteMessage?chat_id=123456789&message_id=123456,

It is important that the id of the message temine with a (comma) (,) and you can see it in the json when you send the message
