- Required fields: `name` (Your name), `email` (Email address), `attendeePhoneNumber` (Best phone number to reach you), `notes` (What's complicated in your business right now?)
- Optional fields: `guests` (Add guests)
- `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.
