When the "SeatSelectAllowed" parameter is absent in a fare quote response, what factors should be considered for seat selection criteria?
"SeatSelectAllowed" is an optional parameter. If the Seat Map is available in the API response(https://flight.srdvtest.com/v8/rest/SeatMap), then you may display the seat map on the frontend accordingly. In case the seat map is not returned in the response, seat selection will not be applicable for that booking.
