Как узнать какой товар был куплен у телеграм бота

У меня есть бот для покупки ключей для игр.

Как сделать чтоб в функции successful payment печатало какой товар был куплен?

dp = Dispatcher(bot)
payment="payment"

    await message.answer("/buy чтоб купить ключ к игре")

    kb = types.InlineKeyboardMarkup()
    rust = types.InlineKeyboardButton(text='Купить RUST', callback_data='rust')
    gta5 = types.InlineKeyboardButton(text='Купить GTA5', callback_data='gta5')
    kb.add(rust, gta5)
    await bot.send_message(message.chat.id, "Какую игру хотите купить?",reply_markup=kb)

PRICE = types.LabeledPrice(label='RUST', amount=100 + 100)
PRICE2 = types.LabeledPrice(label='GTA5', amount=1000 + 1000)
