Procedure
Air Traffic Control requested that Aircraft X fly a heading of 110; and maintain 3;000 ft. until established on the localizer for Runway XXL ILS approach. Once established on the heading of 110; and stabilized; Air Traffic Control advised the crew of opposite direction traffic. Traffic was within 500 ft. of Aircraft X; and when the traffic ascended to less than 400 ft.; the Traffic Advisory warning initiated; 'Traffic. Traffic. Climb.' The autopilot was immediately disengaged; and the advisory was followed to climb; then updated to bank left. Final deviation altitude was 3;200 ft. MSL; and was quickly corrected to the assigned 3;000 ft. when traffic was no factor. Air Traffic Control was advised of the deviation.
We were on a heading to intercept approach path for Runway XXL into ZZZ. Approach gave us heading 110 degrees to intercept and maintain 3;000 ft. until established on the ILS XXL approach. As we turned to 110 degrees and established Approach also mentioned traffic opposite direction while were looking outside we told Approach LOOKING FOR TRAFFIC. Once we were established on heading received Traffic Advisory warning advise to turn and climb at approximately 400 ft. closing to 200 ft. I disengaged autopilot as I turned and climbed following traffic advisory warning. My First Officer advised ATC about traffic advisory and deviation. We then returned to 3;000 ft. and established on approach.
