interface -

public interface FirstApi {
public static String URl = "http://www.fabgrad.com/";

@FormUrlEncoded
@POST("dummy_api_1")
Call<Titles> getData(@Field("us_id") String id);

    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(FirstApi.URl)
            .addConverterFactory(GsonConverterFactory.create())
            .build();

    FirstApi categoryMenuApi = retrofit.create(FirstApi.class);

    String s="23";
    Call<Titles> categoryMenuCall = categoryMenuApi.getData(s);

    categoryMenuCall.enqueue(new Callback<Titles>() {
        @Override
        public void onResponse(Call<Titles> call, Response<Titles> response) {


            Titles list = response.body();

        }

        @Override
        public void onFailure(Call<Titles> call, Throwable t) {

            Toast.makeText(getApplicationContext(), t.getMessage(), Toast.LENGTH_SHORT).show();
        }
    });

You only have to add / at the end of your endpoint @POST("dummy_api_1")

Just like:

@POST("dummy_api_1/")
