You can try the below code to get 400 response. You can get error response from errorBody() method.

Call.enqueue(new Callback() {
    @Override
    public void onResponse(Call call, Response response) {
        //get success and error response here
 if (response.code() == 400) {
                if(!response.isSuccessful()) {
                    JSONObject jsonObject = null;
                    try {
                        jsonObject = new JSONObject(response.errorBody().string());
                        String userMessage = jsonObject.getString("userMessage");
                        String internalMessage = jsonObject.getString("internalMessage");
                        String errorCode = jsonObject.getString("errorCode");
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }
            }

    @Override
    public void onFailure(Call call, Throwable t) {
        //get failure response here
    }
}
}

EDIT: Fixed method name from toString to string
