API Call not successful

Good day Guys,
I am trying to Use an SMS API. Everything looks fine from my end but the SMS is not delivering. If i use the URL directly on Browser, it executes.
Or is anything wrong with how i built the string?
Below is the code.
Please Note tht cbo.Title is a comobox, txtFirstname is a Textbox.
public void NewText()
{
string username = "something#gmail.com";
string password = "Password";
string urlStr;
string message=" Dear " + cbo_Title.Text + " " + txt_FirstName.Text + ", Your New Savings Account Number is " + Account_No + ".Welcome to AGENTKUNLE Global Services. Your Future is Our Priority ";
string sender = "AGENTKUNLE";
string recipient=txt_Phone.Text;
urlStr = "https://portal.nigeriabulksms.com/api/?username="+username+"+password="+password+"+sender="+sender+"+message="+message+"+ mobiles="+recipient;
Uri success = new Uri(urlStr);
}

private string SendSms(string apiUrl)
{
var targetUri = new Uri(apiUrl);
var webRequest = (HttpWebRequest) WebRequest.Create(targetUri);
webRequest.Method = WebRequestMethods.Http.Get;
try
{
string webResponse;
using (var getresponse = (HttpWebResponse) webRequest.GetResponse())
{
var stream = getresponse.GetResponseStream();
if (stream != null)
using (var reader = new StreamReader(stream))
{
webResponse = reader.ReadToEnd();
reader.Close();
}
else
webResponse = null;
getresponse.Close();
}
if (!string.IsNullOrEmpty(webResponse?.Trim()))
return webResponse.Trim();
}
catch (WebException ex)
{
ErrorHelper.Log(ex);
}
catch (Exception ex)
{
ErrorHelper.Log(ex);
}
finally
{
webRequest.Abort();
}
return null;
}

You never make a request.
The Uri object is just a container for the uri (see Microsoft Docs).
Check out the HttpClient class if you want to send a request.

Microsoft Translator fails returning 400 continually

I implemented the MS Translator API a C# console app.
My subscription level is a premium pay account, NOT the free level.
Each time I begin calling it, the first 1-5 translations work fine.
After that I get and endless stream of 400 (Bad Request) exceptions.
Here is the text response I'm getting:
Response Text: TranslateApiException Method: Translate() Message:
Cannot find an active Azure Market Place Translator Subscription
associated with the request credentials.message
id=3832.V2_Rest.Translate.117038D9
What am I missing? I am most definitely including the app id and secret key in the code?
Am I intended to also provide some additional credentials?
Here is my Translator class:
Any ideas?

Look at the content of the response. It will contain the cause of the error in human-readable form.
It is likely that you do not have a subscription associated with the credentials of your request. To fix that:
Visit https://datamarket.azure.com/account/datasets and make sure you have a subscription to "Microsoft Translator - Text Translation".
Visit https://datamarket.azure.com/developer/applications and define a client ID and password.
Use that client ID and password in your application.

I'm in trouble with getting the response for a HTTP POST Request

I'm trying to get a http response from a web server which asks for my credentials in application/json. Although on their website they say I have to use POST Request, I get 405 HTTP status and a WebException as an answer. Here is my code:
private bool RunAuth(bool b, String user, String pass)
{
if(b)
{
HttpWebRequest h = (HttpWebRequest)WebRequest.Create("https://authserver.mojang.com/");
h.Method = "POST";
h.KeepAlive = false;
h.ContentType = "application/json";
String json = "{" + "\"agent\": {" + "\"name\": \"Minecraft\"," + "\"version\": 1" + "}," + "\"username\": \""+user+"\"," + "\"password\": \""+pass+"\"," + "\"clientToken\": \"" + tokenGenerated + "\"" + "}"; //tokenGenerated = Guid.NewGuid().ToString();
h.ContentLength = json.Length;
using(var stream = new StreamWriter(h.GetRequestStream()))
{
stream.Write(json);
stream.Flush();
stream.Close();
}
HttpWebResponse r = (HttpWebResponse)h.GetResponse();
using (var stream = new StreamReader(r.GetResponseStream()))
{
String result = stream.ReadToEnd();
File.WriteAllText(appdata + #"\.craftunio\authtest.txt", result);
}
return true;
}
else
{
return false;
}
}

You are calling the wrong endpoint. You should call
HttpWebRequest h = (HttpWebRequest)WebRequest.Create("https://authserver.mojang.com/authenticate");

While uploading tracks to soundcloud(422) Unprocessable Entity)

I would like to try upload a mp3 file to my soundcloud account. I have written this code for this job.
WebClient client = new WebClient();
string postData = "client_id=" + "xxxxx"
+ "&client_secret=" + "xxx"
+ "&grant_type=password&username=" + "xxx" //your username
+ "&password=" + "xxx";//your password :)
string soundCloudTokenRes = "https://api.soundcloud.com/oauth2/token";
string tokenInfo = client.UploadString(soundCloudTokenRes, postData);
tokenInfo = tokenInfo.Remove(0, tokenInfo.IndexOf("token\":\"") + 8);
string token = tokenInfo.Remove(tokenInfo.IndexOf("\""));
System.Net.ServicePointManager.Expect100Continue = false;
var request = WebRequest.Create("https://api.soundcloud.com/tracks") as HttpWebRequest;
request.CookieContainer = new CookieContainer();
//some default headers
request.Accept = "*/*";
request.Headers.Add("Accept-Charset", "ISO-8859-1,utf-8;q=0.7,*;q=0.3");
request.Headers.Add("Accept-Encoding", "gzip,deflate,sdch");
request.Headers.Add("Accept-Language", "en-US,en;q=0.8,ru;q=0.6");
//file array
var files = new UploadFile[] { new UploadFile(filePath, "#/" + filePath, "application/octet-stream") };
//other form data
var form = new NameValueCollection();
form.Add("track[title]", "biksad");
form.Add("track[sharing]", "public");
form.Add("oauth_token", token);
form.Add("format", "json");
form.Add("Filename", fileName);
form.Add("Upload", "Submit Query");
string lblInfo;
try
{
using (var response = HttpUploadHelper.Upload(request, files, form))
{
using (var reader = new StreamReader(response.GetResponseStream()))
{
lblInfo = reader.ReadToEnd();
}
}
}
catch (Exception ex)
{
lblInfo = ex.ToString();
}
}
When I debug this code part. I get (422) Unprocessable Entity error in catch block. Why I get this error? How can solve this problem?

Check the Soundcloud documentation:
http://developers.soundcloud.com/docs#errors
422 - "The request looks alright, but one or more of the parameters looks a little screwy. It's possible that you sent data in the wrong format (e.g. an array where we expected a string)."

Linked In API (auth token (oauth2)) c#.net

I wonder if someone can give me some pointers on using the linked in API. I thought I had it sussed but for some reason when trying to get the auth_token I just get http 400 Bad Request.
My code, simply is:
public string redirectUrl = URLTOREDIRECT;
public String apiKey = APIKEY;
public String apiSecret = APISECRET;
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
if (Request.QueryString["code"] != null)
{
VerifyAuthentication(Request.QueryString["code"]);
}
}
}
protected void Button1_Click(object sender, EventArgs e)
{
Response.Redirect("https://www.linkedin.com/uas/oauth2/authorization?response_type=code&client_id=apiKey&scope=rw_company_admin&state=DCEEFWF45453sdffef424&redirect_uri=" + HttpUtility.HtmlEncode(redirectUrl));
}
public String VerifyAuthentication(string code)
{
string authUrl = "https://www.linkedin.com/uas/oauth2/accessToken";
var sign = "grant_type=authorization_code" + "&code=" + code + "&redirect_uri=" + HttpUtility.HtmlEncode(redirectUrl) + "&client_id=" + _consumerkey + "&client_secret=" + _consumerSecret;
// var postData = String.Format("grant_type=authorization_code&code={0}&redirect_uri={1}&client_id={2}&client_secret={3}", code, HttpUtility.HtmlEncode(redirectUrl), apiKey, apiSecret);
HttpWebRequest webRequest = WebRequest.Create(authUrl + "?" + sign) as HttpWebRequest;
webRequest.Method = "POST";
//This "application/x-www-form-urlencoded"; line is important
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.ContentLength = sign.Length;
StreamWriter requestWriter = new StreamWriter(webRequest.GetRequestStream());
requestWriter.Write(sign);
requestWriter.Close();
StreamReader responseReader = new StreamReader(webRequest.GetResponse().GetResponseStream());
return responseReader.ReadToEnd().ToString() ;
}
The code is all in the same page for testing purposes and is the same page as the redirectUrl.
Really stumped, tried all variations.
First bit clearly works as I get directed to linked in to allow app. The second part getting the auth token fails.

After much head scratching, eureka moment - did not need to send the info in the request.
string authUrl = "https://www.linkedin.com/uas/oauth2/accessToken";
var sign = "grant_type=authorization_code&code=" + HttpUtility.UrlEncode(code) + "&redirect_uri=" + HttpUtility.HtmlEncode(redirectUrl) + "&client_id=" + apiKey + "&client_secret=" + apiSecret;
//byte[] byteArray = Encoding.UTF8.GetBytes(sign);
HttpWebRequest webRequest = WebRequest.Create(authUrl + "?" + sign) as HttpWebRequest;
webRequest.Method = "POST";
webRequest.ContentType = "application/x-www-form-urlencoded";
Stream dataStream = webRequest.GetRequestStream();
String postData = String.Empty;
byte[] postArray = Encoding.ASCII.GetBytes(postData);
dataStream.Write(postArray, 0, postArray.Length);
dataStream.Close();
WebResponse response = webRequest.GetResponse();
dataStream = response.GetResponseStream();
StreamReader responseReader = new StreamReader(dataStream);
String returnVal = responseReader.ReadToEnd().ToString();
responseReader.Close();
dataStream.Close();
response.Close();
return returnVal;
