Content-Type: application/json

{
  "eventTypeId": 7168889,

- Required fields: `name` (Your name), `email` (Email address), `attendeePhoneNumber` (Phone number), `notes` (What problem do you want to solve?)
- 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.
- A successful response is a pending booking request.
