Narrative: While taxing to the gate and on the terminal ramp the 4th Flight Attendant called up and stated there was smoke in the cabin. She stated 'could be electrical'. I stopped the aircraft; I got a minor whiff of something but it dissipated immediately. FO (First Officer) smelled nothing. We reported smoke in the cabin to ground and requested Airport rescue and Fire Fighting. We considered running the Smoke/AVIONICS SMOKE/Fumes but needed more information; (global assessment). I called up the 1st and she stated she was unaware of what was going on. I called back to the rear of the aircraft and 2nd stated it had begun to dissipate. After a brief discussion with FO; I elected to taxi to the gate and have Airport Rescue and Fire Fighting follow us and access the situation. Aircraft deplaned normally. 1st was unaware there was an issue 4th thought it was an electrical odor 2nd stated there was an odor but not a burning odor. He noticed a lite haze in the reading lights. [The possible cause] was primarily due to the dark cabin; communications among cabin crew. In a perfect world; there would have been better communication between all of the flight attendants; prior to calling up the flight deck. A more concrete assessment could have made with all eyes on the situation. Then the degree of urgency; and solid information can be transmitted more efficiently to the Captain.


Second narrative: Taxiing to the gate on the terminal ramp we received a cabin call from the #4 FA (Flight Attendant) reporting smoke in the cabin. CA stopped the aircraft to assess the situation and asked if I smelled smoke or odor. I did not see or smell smoke or odor in the cockpit. CA said he sensed a brief odor but not burning. We called ground to request Airport Rescue and Fire Fighting due to the cabin smoke report. We discussed completing the Smoke/AVIONICS SMOKE/ Fumes checklist but after a follow up call to the FAs about the cabin environment the #1 said she didn't see or smell smoke or odor and #2 and #4 said the smoke/odor had dissipated. Due to close proximity to the gate CA decided to continue to the gate for further evaluation by the Airport Rescue and Fire Fighting personnel. The smoke report was entered in the AML and the fumes report [was] completed.
