- Required fields: `name` (Your name), `email` (Email address), `The-one-thing-that-takes-most-of-your-time` (The one thing that takes most of your time), `paid-hour-cancellation-check` (I ask you to start the session within 14 days, and I understand I lose my right to cancel once it has been fully delivered.)
- Optional fields: `guests` (Add guests), `Business-name` (Business name)
- `name` and `email` go in `attendee` and `guests` is a list of emails; every other field goes in `bookingFieldsResponses` under its name.
- `location` is optional; without it the booking uses the event’s first location.
