Arguments:
amount -- the amount of money to ask
email -- the email of the customer (optional)
usually redundant with the hardwired settings in the bank
configuration panel. At this url you must use the Payment.response
method to analyze the bank returned values.
It returns a triple of values, (transaction_id, kind, data):
- the first gives a string value to later match the payment with
the invoice,
- kind gives the type of the third value, payment.URL or
payment.HTML or payment.FORM,
- the third is the URL or the HTML form to contact the payment
server, which must be sent to the customer browser.
