answerPreCheckoutQuery method
Once the user has confirmed their payment and shipping details, the Bot API sends the final confirmation in the form of an Update with the field pre_checkout_query.
Use this method to respond to such pre-checkout queries.
On success, True is returned.
Note: The Bot API must receive an answer within 10 seconds after the pre-checkout query was sent.
