FORMER DATA:
{
  "data": {
    "tour": {
      "vehicle": "car",
      "status": "finished",
      "distance": 3854.4610000000002,
      "id": "14bb75b5-97bf-4143-8a21-ad512565aecb"
    }
  }
}

In this example, the vehicle of a tour will be changed from "car" to "bike". Therefore, the "key" of the mutation will be "vehicle" and the "value" will be "bike".

WRITING THE MUTATION:

mutation {
  updateTour(
    tourid: "14bb75b5-97bf-4143-8a21-ad512565aecb"
    key: "vehicle"
    value: "bike"
  ) {
    vehicle
    status
    distance
    id
  }
}
