Как отправить почтовый запрос с контентом типа x- www-form-urlencoded android дооснащение

У меня проблема с отправкой запроса с типом контента как x- www-form-urlencoded в android дооснащении. Не уверен насчет ошибки, которую я делаю при отправке почтового запроса. Когда тот же запрос отправляется почтальоном, я могу получить ожидаемый правильный ответ. Более того, я попытался отправить тот же ответ через форму html и получил успешный ответ 

public class RequestManager {

    private static Retrofit retrofit;

    private static final String BASE_URL = "https://ipguat.apps.net.pk/Ecommerce/api/Transaction/";
    private OkHttpClient okhttpClient;

    static Gson gson = new GsonBuilder()
            .setLenient()
            .create();

    public static Retrofit getRetrofitInstance() {
        if (retrofit == null) {
            retrofit = new retrofit2.Retrofit.Builder()
                    .baseUrl(BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create(gson))
                    .build();
        }
        return retrofit;
    }

}

// MainActivity, откуда я отправляю почтовый запрос 

 private void sendPayment(String token) {
        Date c = Calendar.getInstance().getTime();

        SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd");
        String formattedDate = df.format(c);
        Call<ResponseBody> call = service.sendPayment("102", "Arfeen Test", token, "00", "5", "03451234567", "arfeen@arfeen.me", "POSTMAN-TEST-ARF", "01", "Test Purchase", "www.facebook.com", "www.google.com", "TEST-01", formattedDate, "www.youtube.com");
        call.enqueue(new Callback<ResponseBody>() {
                         @Override
                         public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
                             if (response.isSuccessful()) {
                                 try {
                                     renderPage(response.body().string());
                                 } catch (IOException e) {
                                     e.printStackTrace();
                                 }
                             }
                         }

                         @Override
                         public void onFailure(Call<ResponseBody> call, Throwable t) {
                             Toast.makeText(MainActivity.this, "Something went wrong...Please try later!", Toast.LENGTH_SHORT).show();
                         }
                     }
        );


    }

// Интерфейс, где конечная точка для API упоминается 

public interface TokenService {

    @FormUrlEncoded
    @POST("PostTransaction/")
    Call<ResponseBody> sendPayment(@Field("MERCHANT_ID") String id,
                                   @Field("MERCHANT_NAME") String merchantName,
                                   @Field("TOKEN") String token,

Использовать аннотацию @Headers. 

public interface TokenService {

    @FormUrlEncoded
    @Headers("Content-Type:application/x-www-form-urlencoded")
    @POST("PostTransaction/")
    Call<ResponseBody> sendPayment(@Field("MERCHANT_ID") String id,
                                   @Field("MERCHANT_NAME") String merchantName,
                                   @Field("TOKEN") String token,
                                   @Field("PROCCODE") String proccode,
                                   @Field("TXNAMT") String transaction,
                                   @Field("CUSTOMER_MOBILE_NO") String mobile,
                                   @Field("CUSTOMER_EMAIL_ADDRESS") String email,
                                   @Field("SIGNATURE") String signature,
                                   @Field("VERSION") String version,
                                   @Field("TXNDESC") String productDescription,
                                   @Field("SUCCESS_URL") String successUrl,
                                   @Field("FAILURE_URL") String failureUrl,
                                   @Field("BASKET_ID") String basketID,
                                   @Field("ORDER_DATE") String orderDate,
                                   @Field("CHECKOUT_URL") String checoutUrl);

}

Попробуйте настроить OkhttpClient,
