- Required fields: `name` (Your name), `email` (Email address), `title` (What is this meeting about?), `smsReminderNumber` (Phone number (Text notifications))
- 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.
- `lengthInMinutes` picks one of 15, 30, 60; pass the same value to the slots request as `duration`.
