+Booking Additional Fields
+=========================
+
+You can also create the addtional fields for your booking, you just need to compile
+them in your PrenotazioneType.
+And they will appear in the ["booking_types"]["booking_additional_fields_schema"]
+in your booking schema so you can compile them for your booking in this way:
+
+@booking
+--------
+
+Create booking with an additional field
+

+This endpoint allows to create a new booking.
