InlineKeyboardMarkup doesn't send keyboard via Telegram API. Why?

Question

Telegram

I send the keyboard through a post request, the request is processed, but the keyboard does not come to the chat. What could be the problem?

def sendKeyboard(self, text):
sendText = str(keyboard)
InlineKeyboardButton = {"text":"hey", "url":"http://google.com"}
keyboard = [InlineKeyboardButton]
inline_keyboard = [keyboard]
answer = {'chat_id': self.chat_id, 'text': sendText, 'reply_markup':inline_keyboard}
url = self.URL + "/sendMessage"

You need to pass one more parameter
