- Required fields: `name` (Your name), `email` (Email address), `title` (What do you do, and how long have you been in business?), `Q2` (What has brought you to me? e.g. drowning in admin, struggling with bookkeeping, need automation but don't know where to start.), `Q3` (If you could take one task off your to-do list forever, what would it be?), `Q4` (How did you find me?), `Q5` (Are you looking for one-off or ongoing support? (it's okay not to know the answer to this!))
- Optional fields: none
- `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.
