I added all things related to stripe server guide but did not work for
me Here is my code i did not added stripe key and please also guide me
where i add stripe key and yet in response null return in body.please
guide me if you have any idea.

 try {

            HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();

            interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);

            OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();



            // Change base URL to your upload server URL.

            service = new Retrofit.Builder().baseUrl("https://uploads.stripe.com/v1/files/").client(client).build().create(InterfaceService.class);

        } catch (Exception e) {

            e.printStackTrace();

        }



//                File file = new File(filePath);



        RequestBody reqFile = RequestBody.create(MediaType.parse("image/*"), actualFile);

        MultipartBody.Part body = MultipartBody.Part.createFormData("file", fileName, reqFile);

        RequestBody name = RequestBody.create(MediaType.parse("text/plain"), "upload_test");







//            Log.d("THIS", data.getData().getPath());



        Map<String, RequestBody> fileUploadParams = new HashMap<>();

        fileUploadParams.put("purpose", InterfaceService.createRequestBody("identity_document"));

                fileUploadParams.put("file", InterfaceService.createRequestBody(actualFile));



        retrofit2.Call<ResponseBody> req = service.uploadFileWithPartMap(fileUploadParams, body);

        req.enqueue(new Callback<ResponseBody>() {

            @Override

            public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {

here is complete solution for upload file on stripe

 multipart = new MultipartUtility("https://uploads.stripe.com/v1/files", "");



                    // In your case you are not adding form data so ignore this

                    /*This is to add parameter values */

                    multipart.addFormField("purpose", "identity_document");

                    multipart.addFilePart("file", new File(frontPath));

                    response = multipart.finish();
