Is it possible to pre-fill fields in revolut.me?

The “Pay me” Revolut page, available at https://revolut.me/<username> has fields for currency, amount and note. Is it possible to pre-fill these, perhaps with query string params? I've tried https://revolut.me/vrana?amount=100&comment=Adminer (which are the values of name attributes of the fields) but with no luck. I even tried POSTing these fields to the form from an external page resulting in 405 Not Allowed.
