- Required fields: `name` (Your name), `email` (Email address), `link` (Website/App link (if applicable)), `text` (What exactly do you need help with?), `select` (How did you find me?)
- 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.
- `lengthInMinutes` picks one of 15, 25; pass the same value to the slots request as `duration`.
