How to fix The remote server returned an error: (403) Forbidden. dailymotion api

So I am using the Dailymotion API for uploading the video and use the code I get from the GitHub and it works perfectly but after 4 videos it gives the exception:
{"The remote server returned an error: (403) Forbidden."}
And I am getting an error in PublishVideo method
var response = request.GetResponse();
Main Code
var accessToken = GetAccessToken();
Authorize(accessToken);
Console.WriteLine("Access token is " + accessToken);

Console.WriteLine(response + "\n");

Console.ReadLine();

}
}

It could be related to many causes. I suggest you to catch the error and get the response stream from our API:
try{
var response = request.GetResponse();
var responseStream = response.GetResponseStream();
string responseString;
using (var reader = new StreamReader(responseStream))
{
responseString = reader.ReadToEnd();
}
var uploadedResponse = JsonConvert.DeserializeObject<UploadedResponse>(responseString);
return uploadedResponse;
}
catch(WebException e){
var rs = e.Response.GetResponseStream();
string errorResponseString;
using (var reader = new StreamReader(rs))
{
errorResponseString = reader.ReadToEnd();
}
Console.WriteLine(errorResponseString);
return null;
}
You will get a message explaining you why your access is forbidden.
I also invite you to check our API rate limit rules which can be a cause of forbidden call: https://developer.dailymotion.com/api/#rate-limit

Big beer for person which can repair this..
Code from VS with errors (screen)
MY code:
string returnData = String.Empty;
var webRequest = HttpWebRequest.Create(url) as HttpWebRequest;

"ACCESS_SIGNATURE: " + signature,
"ACCESS_NONCE: " + nonce
};
webRequest.Headers = whc;
using (WebResponse response = webRequest.GetResponse())
{
using (Stream stream = response.GetResponseStream())
{
StreamReader reader = new StreamReader(stream);
returnData = reader.ReadToEnd();
}
}
}

How to get OTCSticket with api/v1/auth method=post in content server using c#

Following is the API Call i make using postman and get a ticket back in the response body (screenshot):
I am not able to get the ticket in a HttpWebRequest Response in C#. Please below see the small sample code:
C# code
HttpWebRequest Request = WebRequest.Create(strUrl) as HttpWebRequest;
Request.Method = "POST";
Request.Headers.Add("Authorization", "Basic <>");
//Request.ContentType = "application/form-data";
Request.KeepAlive = true;
string data = string.Format("username=" + UserName + "&password=" + Password);
byte[] dataStream = Encoding.UTF8.GetBytes(data);
Request.ContentLength = dataStream.Length;
using (Stream newStream = Request.GetRequestStream())
{
// Send the data.
newStream.Write(dataStream, 0, dataStream.Length);
newStream.Close();
}
var Response = (HttpWebResponse)Request.GetResponse();
using (var stream = Response.GetResponseStream())
using (var reader = new StreamReader(stream))
{
if (Response.StatusCode != HttpStatusCode.OK)
throw new Exception("The request did not complete successfully and returned status code " + Response.StatusCode);
ResponseTicket strTicket= JsonConvert.DeserializeObject<ResponseTicket>(reader.ToString());
JsonConvert.DeserializeObject(Response.GetResponseStream().ToString());
MessageBox.Show(strTicket.Ticket);
}
Where as statuscode=200. But the content length is 0.
It is very difficult to find any meaning full help on CS10.5 API. I have checked there AppWorks platform but in vain. Would appreciate if someone can find the problem in the code, which apparently i can not see.

I don't know if this is still an issue for you. For me it was also, but figured it out:
public string LoginAsAdminAndRetrieveTicket(string userName, string passWord, string domain, string url)
{
var uri = $"http://{url}/otcs/llisapi.dll/api/v1/auth";
var request = new HttpRequestMessage();
request.Headers.Add("Connection", new[] { "Keep-Alive" });
request.Headers.Add("Cache-Control", "no-cache, no-store, must-revalidate");
request.Headers.Add("Pragma", "no-cache");
request.RequestUri = new Uri(uri);
request.Method = HttpMethod.Post;
request.Content = new StringContent($"username={userName};password={passWord}", Encoding.UTF8, "application/x-www-form-urlencoded");
var httpClientHandler = new HttpClientHandler
{
Proxy = WebRequest.GetSystemWebProxy(),
UseProxy = true,
AllowAutoRedirect = true
};
using (var client = new HttpClient(httpClientHandler))
{
var response = client.SendAsync(request).Result;
string ticket;
var vals = response.Headers.TryGetValues("OTCSTicket", out IEnumerable<string> temp) ? temp : new List<string>();
if (vals.Any())
{
ticket = vals.First();
}
return response.Content.ReadAsStringAsync().Result;
}
}

Add param POST request using HttpWebRequest async windows phone 8 - JSON [duplicate]

I need to call a method from a webservice, so I've written this code:
private string urlPath = "http://xxx.xxx.xxx/manager/";
string request = urlPath + "index.php/org/get_org_form";
WebRequest webRequest = WebRequest.Create(request);
webRequest.Method = "POST";
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.
webRequest.ContentLength = 0;
WebResponse webResponse = webRequest.GetResponse();
But this method requires some parameters, as following:
Post data:
_username:'API USER', // api authentication username
_password:'API PASSWORD', // api authentication password
How can I add these parameters into this Webrequest?

Use stream to write content to webrequest
string data = "username=<value>&password=<value>"; //replace <value>
byte[] dataStream = Encoding.UTF8.GetBytes(data);
private string urlPath = "http://xxx.xxx.xxx/manager/";
string request = urlPath + "index.php/org/get_org_form";
WebRequest webRequest = WebRequest.Create(request);
webRequest.Method = "POST";
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.ContentLength = dataStream.Length;
Stream newStream=webRequest.GetRequestStream();
// Send the data.
newStream.Write(dataStream,0,dataStream.Length);
newStream.Close();
WebResponse webResponse = webRequest.GetResponse();

If these are the parameters of url-string then you need to add them through '?' and '&' chars, for example http://example.com/index.aspx?username=Api_user&password=Api_password.
If these are the parameters of POST request, then you need to create POST data and write it to request stream. Here is sample method:
private static string doRequestWithBytesPostData(string requestUri, string method, byte[] postData,
CookieContainer cookieContainer,
string userAgent, string acceptHeaderString,
string referer,
string contentType, out string responseUri)
{
var result = "";
if (!string.IsNullOrEmpty(requestUri))
{
var request = WebRequest.Create(requestUri) as HttpWebRequest;
if (request != null)
{
request.KeepAlive = true;
var cachePolicy = new RequestCachePolicy(RequestCacheLevel.BypassCache);
request.CachePolicy = cachePolicy;
request.Expect = null;
if (!string.IsNullOrEmpty(method))
request.Method = method;
if (!string.IsNullOrEmpty(acceptHeaderString))
request.Accept = acceptHeaderString;
if (!string.IsNullOrEmpty(referer))
request.Referer = referer;
if (!string.IsNullOrEmpty(contentType))
request.ContentType = contentType;
if (!string.IsNullOrEmpty(userAgent))
request.UserAgent = userAgent;
if (cookieContainer != null)
request.CookieContainer = cookieContainer;
request.Timeout = Constants.RequestTimeOut;
if (request.Method == "POST")
{
if (postData != null)
{
request.ContentLength = postData.Length;
using (var dataStream = request.GetRequestStream())
{
dataStream.Write(postData, 0, postData.Length);
}
}
}
using (var httpWebResponse = request.GetResponse() as HttpWebResponse)
{
if (httpWebResponse != null)
{
responseUri = httpWebResponse.ResponseUri.AbsoluteUri;
cookieContainer.Add(httpWebResponse.Cookies);
using (var streamReader = new StreamReader(httpWebResponse.GetResponseStream()))
{
result = streamReader.ReadToEnd();
}
return result;
}
}
}
}
responseUri = null;
return null;
}

For doing FORM posts, the best way is to use WebClient.UploadValues() with a POST method.

Hope this works
webRequest.Credentials= new NetworkCredential("API_User","API_Password");

I have a feeling that the username and password that you are sending should be part of the Authorization Header. So the code below shows you how to create the Base64 string of the username and password. I also included an example of sending the POST data. In my case it was a phone_number parameter.
string credentials = Convert.ToBase64String(Encoding.ASCII.GetBytes(_username + ":" + _password));
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(Request);
webRequest.Headers.Add("Authorization", string.Format("Basic {0}", credentials));
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.Method = WebRequestMethods.Http.Post;
webRequest.AllowAutoRedirect = true;
webRequest.Proxy = null;
string data = "phone_number=19735559042";
byte[] dataStream = Encoding.UTF8.GetBytes(data);
request.ContentLength = dataStream.Length;
Stream newStream = webRequest.GetRequestStream();
newStream.Write(dataStream, 0, dataStream.Length);
newStream.Close();
HttpWebResponse response = (HttpWebResponse)webRequest.GetResponse();
Stream stream = response.GetResponseStream();
StreamReader streamreader = new StreamReader(stream);
string s = streamreader.ReadToEnd();

The code below differs from all other code because at the end it prints the response string in the console that the request returns. I learned in previous posts that the user doesn't get the response Stream and displays it.
//Visual Basic Implementation Request and Response String
Dim params = "key1=value1&key2=value2"
Dim byteArray = UTF8.GetBytes(params)
Dim url = "https://okay.com"
Dim client = WebRequest.Create(url)
client.Method = "POST"
client.ContentType = "application/x-www-form-urlencoded"
client.ContentLength = byteArray.Length
Dim stream = client.GetRequestStream()
//sending the data
stream.Write(byteArray, 0, byteArray.Length)
stream.Close()
//getting the full response in a stream
Dim response = client.GetResponse().GetResponseStream()
//reading the response
Dim result = New StreamReader(response)
//Writes response string to Console
Console.WriteLine(result.ReadToEnd())
Console.ReadKey()
