On a flight to ZZZ everything [was] normal until shortly before we descended on the arrival. We received an ECAM (Electronic Centralized Aircraft Monitor) caution indicating a fuel imbalance which required us to run the fuel leak checklist. After running the checklist we could not verify that we did indeed have a fuel leak. We enlisted the help of a company Airbus Check Airman who was riding as a passenger to do a visual inspection of the wings and engine. He reported back to us that there were no visible signs of a fuel leak. We decided to [advise] ATC in the event we had a fuel leak and continue on to ZZZ as it was the nearest suitable airport. Flight attendants; passengers and Dispatch were notified of our situation. We then requested ARFF (Aircraft Rescue and Fire Fighting) assistance upon landing on Runway XX; as it is the longest runway. Upon routine landing we stopped on the runway where ARFF did a visual inspection and reported no visible signs of a fuel leak. We then taxied to the gate and contacted Maintenance.
A321 First Officer reported a fuel imbalance alert occurred in flight.
