Why can't my Telegram bot send messages to a supergroup?

I’m having trouble with my Telegram bot sending messages to a supergroup. Here’s a simplified version of my code:

async void HandleMessage(MessageEventArgs e)
{
    var msg = e.Message;
    if (msg?.Type == MessageType.Text)
    {
        await BotClient.SendTextMessageAsync(msg.Chat.Id, "Hey there!");
    }
}

This works fine when the bot is in a regular group. But when I try sending a message directly to a supergroup with its ID using:

await BotClient.SendTextMessageAsync(supergroupId, "Hey there!");

Nothing happens. No errors, just silence. I’ve checked all the group permissions and even removed and re-invited the bot to the supergroup. What else could be the issue?

hey, try using getChat() method to check if ur bot can access the supergroup. sometimes tg api is weird with permissions. also, make sure ur using the right ID format (-100…). if that dont work, maybe try creating a new bot token? gl mate!

I’ve dealt with this exact problem before, and it can be frustrating. One thing that often gets overlooked is the bot’s privacy mode. By default, Telegram bots have privacy mode enabled, which restricts their ability to see messages in groups unless they’re explicitly mentioned or replying to a command.

To fix this, you need to disable privacy mode for your bot. Here’s how:

  1. Open a chat with @BotFather on Telegram
  2. Send the /mybots command
  3. Select your bot
  4. Choose ‘Bot Settings’
  5. Select ‘Group Privacy’
  6. Choose ‘Turn off’

After doing this, remove and re-add your bot to the supergroup. This should solve the issue and allow your bot to send messages freely. If it still doesn’t work, double-check the supergroup ID and make sure you’re using the long format (starting with -100) as mentioned by others. Good luck!

I’ve encountered this issue before, and it’s often related to the bot’s permissions within the supergroup. Even if you’ve invited the bot, it might not have the necessary rights to post messages. Double-check that the bot has been promoted to an admin in the supergroup with the ‘Send Messages’ permission enabled. If that doesn’t work, try using the getChatMember method to verify the bot’s status in the group. Also, ensure you’re using the correct supergroup ID - it should start with ‘-100’. If all else fails, consider implementing error handling to catch any silent failures and log them for debugging purposes.
