Retrofit2 in Android Fragment how to implement correctly?

I'm using Retrofit 2 to consume an API. I have a service (interface) which returns a list:

@GET("atenciones")
Call<List<Atencion>> getAtenciones(@Query("medico_id") int id, @Query("date1") String date1, @Query("date2") String date2)

Where should I do the request? In the MainActivity which contains the Fragment and send the result list using Bundle? or should do the request in the Fragment? this is a list not a single object. Which is the correct way?

Edit

Try to call retrofit in Fragment, this is my code:

public class FragmentRendicion extends Fragment {

private LinearLayoutManager layoutManager;
View rootView;
APIService api;

public FragmentRendicion() {
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    rootView = inflater.inflate(R.layout.fragment_rendicion, container, false);
    api= ApiUtils.getAPIService();
        getAtenciones();
    return rootView;
}

private void getAtenciones() {
//using static parameters
    Call<List<Atencion>> call= api.getAtenciones(293,"2014-10-13","2014-10-13");
    call.enqueue(new Callback<List<Atencion>>() {
        @Override
        public void onResponse(Call<List<Atencion>> call, Response<List<Atencion>> response) {
            System.out.println("estamos aquiiii "+response.message());
            List<Atencion> atenciones= response.body();
            layoutManager= new LinearLayoutManager(getActivity());
            RecyclerView recycler= (RecyclerView)rootView.findViewById(R.id.rvRendicion);
            recycler.setLayoutManager(layoutManager);
            RvRendicionAdapter rvAdapter= new RvRendicionAdapter(atenciones);
            recycler.setAdapter(rvAdapter);


        }

        @Override
        public void onFailure(Call<List<Atencion>> call, Throwable t) {
            System.out.println("FALLOOOOO:  "+t.getMessage());//HERE RETUNRS NULL
        }
    });

}
}

Can someone tell me is if it correct way to call retrofit2 in fragment?

It depends on the structure of your code but since you are using fragments my best guess is you should do it in the Fragment.

In the onResponseOK of the Retrofit call you will have something like this:

@Override
public void onResponseOK(Response<List<Atencion>> response) {
    ...
    //access data here
}

In the callback you get your list. Pass the list to the adapter of your (I suppose) Recycler/Listview. Access the list like this:

List<Atencion> myList = response.body();
