How to create a payment form in Telegram Bot using pyqiwi?
You need to create a payment form. I don't know how to create a payment request. Don't post links to documentation.

def generate_form_link(pid, account, amount, comment):
"""
Generating an autofilled payment form

"""
url = " https://qiwi.com/payment/form/{0} ".format(pid)
params = {"currency": 643}
params = util.merge_dicts(params, util.split_float(amount))
if comment:
params['comment'] = comment
if account:
params['account'] = account

encoded_params = urlencode(params)

return url + '?' + encoded_params
