What's the best way to implement a pop-up alert in a Telegram bot?

I’m working on a Telegram bot using C# and the Telegram.Bot library. I’ve got the basic functionality down, but now I’m trying to add a pop-up alert that shows up when a user clicks an InlineKeyboardButton.

Has anyone done this before? I’m not sure where to start. I’m looking for something that looks like a small window appearing over the chat, with a message and maybe a close button.

Here’s a rough idea of what I’m aiming for:

// Pseudo-code for pop-up alert
async Task ShowPopupAlert(ITelegramBotClient botClient, long chatId, string message)
{
    // Some code to create and display a pop-up
    await botClient.SendPopupAlertAsync(chatId, message);
}

Any tips or code snippets would be super helpful. Thanks in advance!

hey mate, i’ve had sum luck with this. u can use AnswerCallbackQueryAsync like others said, but if u want more control, try sendin a new message with ur alert content and an inline keyboard to close it. its not a true popup, but it works pretty good. just remeber to delete the message when the user hits ‘close’. goodluck!

I’ve been working with Telegram bots for some time and have encountered similar challenges. The Telegram bot API doesn’t officially support creating a custom pop-up window. Instead, the built-in method to simulate this behavior is through the answerCallbackQuery function with its show_alert option set to true. In practice, you configure an InlineKeyboardButton with a callback_data value, and then in your callback handler, you call answerCallbackQuery to display a small alert. Although it doesn’t create a fully customizable pop-up, it effectively notifies the user with a simple alert message.

While Telegram doesn’t offer true pop-up alerts, you can achieve a similar effect using AnswerCallbackQueryAsync. This method displays a notification at the top of the chat. Here’s how you might implement it:

async Task HandleCallbackQuery(ITelegramBotClient botClient, CallbackQuery callbackQuery)
{
    await botClient.AnswerCallbackQueryAsync(
        callbackQueryId: callbackQuery.Id,
        text: "Your alert message here",
        showAlert: true
    );
}

Set showAlert to true for a more prominent display. Keep in mind that the message is limited to 200 characters. While not a full pop-up, it’s the closest native option available in Telegram bots. For more complex interactions, consider using inline keyboards or sending separate messages.
