Narrative:

After clearing runway and taxing to the gate. We were told to hold short of taxiway north and to contact ramp. We started the APU and followed ATC instructions. We contacted ramp and was told to hold short for traffic in the alley. Captain told me to shut down engine 2 and turn on the APU bleed to help with cooling. Right after I turned on the bleed we had a dirty wet sock smell in the cockpit and the APU automatically shut down. Was running the ECAM procedure when we got a call from the aft flight attendant (flight attendant). She said there was a smell and haze in the cabin. I told her what happened and said to keep us updated. She asked if I could make an announcement. I made an announcement and told the captain of the situation. At that point I called back and asked if the haze was dissipating which it was; at the same time we got cleared to the gate. Got to the gate without further problems. Wrote up in maintenance log and waited for maintenance. Maintenance did not show up right away; so left the plane.when I came the back; crew was taking their bags off. So I got my bags and went up to gate area and found the captain. Captain said the mechanic told him that the APU blew a seal and what we were smelling was oil. I told him I was feeling nauseous. We decided to go to the er as a crew. They did a blood test and put us on oxygen. Test came back negative and were released. Have had a headache for last two days.
