How do I delete “nameValuePairs” in a JSON request using Retrofit?

Question

I am trying to send raw data in POST request but nameValuePairs key get concated with my JSON.

Here is my request method:-

@Headers( "Content-Type: application/json; charset=utf-8")
    @POST("mpapi/seller/sellerprofilepost")
    Call<ResponseBody>
    updateProfile(@Header("Authorization") String token,
                  @Body JSONObject body);

I am sending this:-

{
    "firstname": "test1ff"
}

but at backend they are receiving :-

{
    "nameValuePairs":
    {
        "firstname":"test1ff"

    }
}

Method for calling api :-

private void updateProfile() {
        try {
            showLoader();
            JSONObject obj=new JSONObject();
            obj.put("firstname",first_name.getText().toString().trim());
            call = api.updateProfile("Bearer k8yu1q0k790lw5y4ta49alfbtsxoxs1w",obj);
            call.enqueue(new Callback<ResponseBody>() {
                @Override
                public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
                    try {
                        if (response.isSuccessful()) {
                            JSONObject obj = new JSONObject(response.body().string());
                            dialog = Func.OneButtonDialog(mContext, obj.getString("message"), ProfileScreen.this);
                        } else {
                            JSONObject obj = new JSONObject(response.errorBody().string());
                            dialog = Func.OneButtonDialog(mContext, obj.getString("message"), ProfileScreen.this);
                        }
                    } catch (Exception e) {
                        dialog = Func.OneButtonDialog(mContext, getResources().getString(R.string.ERROR_MSG), ProfileScreen.this);
                        e.printStackTrace();
                    }
                    hideLoader();
                }

                @Override
                public void onFailure(Call<ResponseBody> call, Throwable t) {
                    dialog = Func.OneButtonDialog(mContext, getResources().getString(R.string.ERROR_MSG), ProfileScreen.this);
                    hideLoader();
                }
            });
        } catch (Exception e) {
            dialog = Func.OneButtonDialog(mContext, getResources().getString(R.string.ERROR_MSG), this);
            hideLoader();
            e.printStackTrace();
        }
    }

Retrofit call method :- here is my retrofit call method where I am setting base url, headers etc

public Retrofit retrofitCall() {
        String baseUrl = Constants.baseURL;
        final OkHttpClient okHttpClient = new OkHttpClient.Builder()
                .sslSocketFactory(getSSLSocketFactory())
                .retryOnConnectionFailure(true)
                .addInterceptor(new AddHeaderInterceptor())
                .readTimeout(40, TimeUnit.SECONDS)
                .connectTimeout(40, TimeUnit.SECONDS)
                .build();
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(baseUrl)
                .client(okHttpClient)
                .addConverterFactory(GsonConverterFactory.create())
                .build();
        return retrofit;
    }

Update your request method code as follow:

@Headers( "Content-Type: application/json; charset=utf-8")
    @POST("mpapi/seller/sellerprofilepost")
    Call<ResponseBody>
    updateProfile(@Header("Authorization") String token,
                  @Body RequestBody body);

In API Calling Method:

    private void updateProfile() {
            try {
                showLoader();
                JSONObject obj=new JSONObject();
                obj.put("firstname",first_name.getText().toString().trim());
                RequestBody bodyRequest = RequestBody.create(MediaType.parse("application/json"), obj.toString());
                call = api.updateProfile("Bearer k8yu1q0k790lw5y4ta49alfbtsxoxs1w",bodyRequest);
                call.enqueue(new Callback<ResponseBody>() {
                    @Override
                    public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
                        try {
                            if (response.isSuccessful()) {
                                JSONObject obj = new JSONObject(response.body().string());
                                dialog = Func.OneButtonDialog(mContext, obj.getString("message"), ProfileScreen.this);
                            } else {
                                JSONObject obj = new JSONObject(response.errorBody().string());
                                dialog = Func.OneButtonDialog(mContext, obj.getString("message"), ProfileScreen.this);
                            }
                        } catch (Exception e) {
                            dialog = Func.OneButtonDialog(mContext, getResources().getString(R.string.ERROR_MSG), ProfileScreen.this);
                            e.printStackTrace();
                        }
                        hideLoader();
                    }

                    @Override
                    public void onFailure(Call<ResponseBody> call, Throwable t) {
                        dialog = Func.OneButtonDialog(mContext, getResources().getString(R.string.ERROR_MSG), ProfileScreen.this);
                        hideLoader();
                    }
                });
            } catch (Exception e) {
                dialog = Func.OneButtonDialog(mContext, getResources().getString(R.string.ERROR_MSG), this);
                hideLoader();
                e.printStackTrace();
            }
        }
