Guest Get

Important — guestId vs guest.id: The guestId field returned by the Guests API is different from the id field embedded inside booking responses (booking.guest.id). Using a guest.id from a booking response to call GET /api/v1/client/guests/{guestId} will return 404 guest_not_found. To get a guest's guestId, use the Search Guests endpoint and read the guestId field from the result. Guests are created automatically when a booking is created.
