            @Field("phone_number") String phone_number ,
            @Field("fax") String fax

Answer 1

Do this way to send Json Object as request parameters using Retrofit 2

    @Headers("Content-Type: application/json")
    @POST("profile_setting/basic_setting")
    Call<ResponseBody> UpdateBasics(@Body String body);

This is how you would use the above method to send json object

try {
                    JSONObject paramObject = new JSONObject();
                    paramObject.put(value_one, "field_one"));
                    paramObject.put(value_second, "field_second"));
                    Call<ResponseBody> userCall = apiInterface.UpdateBasics(paramObject.toString());
                    userCall.enqueue(new Callback<ResponseBody>() {
                        @Override
                        public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
                            //handle your result here

                        }

                        @Override
                        public void onFailure(Call<LoginResponse> call, Throwable t) {
                           //handle failure
                        }
                    });
                } catch (JSONException e) {
                    e.printStackTrace();
                }

Answer 2

Make a class

public class Basic {
  public final int user_id;
  public final String nickname;
  ....

  public Basic(int user_id, ...) {

  }
}

Then pass list of objects of this class to this interface

public interface MyService {
  @POST("/basic")
  Response void sendData(@Body List<Basic> basic);
}

Or you can do the same with JSONObject. Just make a list of jsonobjects

JSONObject paramObject = new JSONObject();
                    paramObject.put(value_one, "field_one"));
                    paramObject.put(value_second, "field_second"));

put the objects in a list

list.add(paramObject);

then pass to the retrofit

public interface MyService {
  @POST("/basic")
  Response void sendJsonObjectData(@Body List<JSONObject> basic);
}

Answer 3

You can follow this was. (posting how i've done that)

@POST("Users.json")
Call<UploadData> uploadToken(@Body UploadData uploadData);

UploadData.class

public class UploadData {

private String DeviceToken, DeviceIMEI;

public UploadData(String deviceToken, String deviceIMEI) {
    DeviceToken = deviceToken;
    DeviceIMEI = deviceIMEI;
}

public String getDeviceToken() {
    return DeviceToken;
}

public String getDeviceIMEI() {
    return DeviceIMEI;
}
}

Then in your Activity

private void uploadToken() {
     ApiInterface apiInterface = ApiClient.getClient().create(ApiInterface.class);
     UploadData uploadToken = new UploadData(deviceToken, imei);
     final Call<UploadData> callUpload = apiInterface.uploadToken(uploadToken);

callUpload.enqueue(new Callback<UploadData>() {
        @Override
        public void onResponse(Call<UploadData> call, Response<UploadData> response) {
             if (response.isSuccessful()) {
                Toasty.success(Main.this, "Token Uploaded !! ", Toast.LENGTH_LONG).show();
              }
      }

       @Override
       public void onFailure (Call < UploadData > call, Throwable t){
              call.cancel();
              Toasty.error(Main.this, "Error: " + t.getLocalizedMessage(),Toast.LENGTH_SHORT).show();
        }
    });

 }
