Core: How to remove service messages in channels?

[WISTFUL12]

I want to remove this service messages from my channel:

bot pinned «new message...»

This is quite easy actually!

When the bot (or any other user) pins a message, a new message object is sent to the bot, which is then handled by the GenericmessageCommand.

So in the execute method you can put the following:

$message = $this->getMessage();
if ($message && $message->getPinnedMessage()) {
    return Request::deleteMessage([
        'chat_id'    => $message->getChat()->getId(),
        'message_id' => $message->getMessageId(),
    ]);
}

    ]);
}

Thanks @noplanman ...

It seems that the deleteMessage never executed...

Request::pinChatMessage([
    'chat_id' => $channel_id,
    'message_id' => $send_message_id,
    'disable_notification' => false,
]);

I put following to GenericmessageCommand's execute method and run above in SurveyCommand, but nothing happened after message pin!

$message = $this->getMessage();
$chat_id = $message->getChat()->getId();

if ($message && $message->getPinnedMessage()) {
    Request::sendMessage([
        'chat_id' => 'My Telegram user ID',
        'text' => print_r($message, 1),
    ]);

    return Request::deleteMessage([
        'chat_id'    => $chat_id,
        'message_id' => $message->getMessageId(),
    ]);
}

You might have to create ChannelpostCommand and put that code there - replace getMessage() with getChannelPost().

@WISTFUL12 I assume it works now and we can close this off?
