I have received ResStatus UN in my Reservation/Book response. What does it mean?

This ResStatus in the Reservation method’s response means that reservation was completed but due to a supplier error or a timeout, the reservation status is unknown, in that case there are one or two things you should do in order to verify the final state of the booking.

  1. You should run a ReservationRead method, in case the supplier permits it, in order to confirm whether the booking was confirmed or not.
  2. In case the state of the booking remains the same in the ReservationRead response, you should contact directly and confirm that state with them.

Note that It is the client’s responsibility to check the final status of the booking.
