- Required fields: `name` (Your name), `email` (Email address), `Results` (What is the result you'd like your audience to have by the time I finish speaking?), `Audience` (Who is your audience? How many do you plan to have an attendance?), `Logistics` (Event date, location & title?)
- Optional fields: `notes` (Additional notes), `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.
