how to read Web APi csv file

Question

Hi Friends,

 

To read data from our client API, first I am login into the URL https://site.com by using username, password and location.

 

After login to get the data another Web API URL is there https://site.com/users/reports/csv?location_id=42&from_date=2020-11-02&to_date=2020-11-05

 

After login, we used this URL the file is automatically downloading in the browser.

 

I want to read this CSV file content and I need to insert the records into the database.

 

for web Api login I wrote this code

var userName = "[email protected]";
var passwd = "5CadcPT";
var url = "https://site.com";
var location= "Hyderabad";
var client = new HttpClient();
var authToken = Encoding.ASCII.GetBytes($"{userName}:{passwd}:{location}");
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic",
Convert.ToBase64String(authToken));
var result1 = await client.GetAsync(url);
var content = await result1.Content.ReadAsStringAsync();
For downloading file I used this code file is downloading but the HTML content is coming in the downloaded CSV file.
stream = await response.Content.ReadAsStreamAsync();
var fileInfo = new FileInfo("reports_2020-11-10 08_14_12.csv");
using (var fileStream = fileInfo.OpenWrite())
{
await stream.CopyToAsync(fileStream);
}

how to do this?
