Inline Query Handling

Use the InlineAttribute to register a method as an inline query handler.

[Inline("example_query")]
public static async Task HandleInlineQuery(ITelegramBotClient bot, InlineQuery query, CancellationToken cancellationToken)
{
    // Handle inline query
}

Edited Message Handling

Use the EditMessageAttribute to register a method as a handler for edited messages.

[EditMessage]
public static async Task HandleEditedMessage(ITelegramBotClient bot, Message message, CancellationToken cancellationToken)
{
    // Handle edited message
}

Command Handling

Use the CommandHandlerAttribute to register a method as a command handler. You can provide only begin of command text. Like, /start act-

[CommandHandler("/start")]
public static async Task StartCommand(ITelegramBotClient bot, Message message, CancellationToken cancellationToken)
{
    // Handle start command
}

Callback Query Handling

Use the CallbackAttribute to register a method as a callback query handler. You can provide only begin of callback data text

[Callback("button_click")]
public static async Task HandleCallbackQuery(ITelegramBotClient bot, CallbackQuery query, CancellationToken cancellationToken)
{
    // Handle callback query
}

PreCheckout Query Handling

Use the PreCheckoutAttribute to register a method as a pre-checkout query handler.

[PreCheckout]
public static async Task HandlePreCheckoutQuery(ITelegramBotClient bot, PreCheckoutQuery query, CancellationToken cancellationToken)
{
    // Handle pre-checkout query
}

General Update Handling

Use the UpdateAttribute to register a method as a generic update handler.

[Update]
public static async Task HandleUpdate(ITelegramBotClient bot, Update update, CancellationToken cancellationToken)
{
    // Handle general update
}
