user/v2/inputfiles API not posting file into file browser t

[vimalkumar2]

I am using below API calls to pass data file into my dummy alteryx workflow and download the same file.

Step1: http:{yourhostname}/api/user/v2/inputfiles

Step2: http:{yourhostname}/api/user/v2/workflows/{appId}/jobs  

Step3: http:{yourhostname}/v1/jobs/{id}/output/{outputId}

Error: Output API is not returning the file uploaded in 1st step.

 Here is my sample code to upload file by api/user/v2/inputfiles

using (var httpClient = new HttpClient())
{
using (var form = new MultipartFormDataContent())
{
form.Add(new StreamContent(File.OpenRead(filePath)), "inputFile", Path.GetFileName(filePath));

httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", tokenInfo);
var response = await httpClient.PostAsync("http:{yourhostname}/api/user/v2/inputfiles", form);
response.EnsureSuccessStatusCode();

var responseBody = await response.Content.ReadAsStringAsync();
return responseBody;
}

}

Kindly suggest if anything wrong with my code and workflow.
