Thanks a lot

What I have tried:

var client = new HttpClient();

            client.BaseAddress = new Uri("xxxx");


            client.DefaultRequestHeaders.Accept.Add(
                    new MediaTypeWithQualityHeaderValue("application/json"));

            var url = "xxxx";

            var logonOptions = new
            {
                username = "xxx",
                password = "xxx",
            };

            JavaScriptSerializer serializer = new JavaScriptSerializer();
            var requestBodyAsString = serializer.Serialize(logonOptions);
            StringContent content =
                new StringContent(
                    requestBodyAsString,
                    Encoding.UTF8,
                    "application/raw"
                );

            HttpResponseMessage response;
            string contributors="";
            try
            {
                response = await client.PostAsync(url, content).ConfigureAwait(false);
                response.EnsureSuccessStatusCode();
                var resp = await response.Content.ReadAsStringAsync();
                contributors = JsonConvert.DeserializeObject<string>(resp);
                
            }
            catch(Exception ex)
            {

            }

C#
new StringContent(... "application/raw");

Your C# code is sending a content type of application/raw, which doesn't match the content type sent in your Postman request.

The API you're calling doesn't understand how to process an application/raw body, so it will most likely return a "bad request" status.

Which you would know if you weren't swallowing all exceptions and throwing away the error details!
