I'am trying to use example api call in below link please check link
http://sendloop.com/help/article/api-001/getting-started
My account is "code5" so i tried 2 codes to get systemDate.
1. Code
var request = WebRequest.Create("http://code5.sendloop.com/api/v3/System.SystemDate.Get/json");
request.ContentType = "application/json; charset=utf-8";
string text;
var response = (HttpWebResponse)request.GetResponse();
using (var sr = new StreamReader(response.GetResponseStream()))
{
text = sr.ReadToEnd();
}
2.Code
HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create("http://code5.sendloop.com/api/v3/System.SystemDate.Get/json");
httpWebRequest.Method = WebRequestMethods.Http.Get;
httpWebRequest.Accept = "application/json";
But i don't know that i use correctly api by above codes ?
When i use above codes i don't see any data or anything.
How can i get and post api to Sendloop.And how can i use api by using WebRequest ?
I will use api first time in .net so
any help will be appreciated.
Thanks.
It looks like you need to post your API key to the endpoint when making requests. Otherwise, you will not be authenticated and it will return an empty response.
To send a POST request, you will need to do something like this:
var request = WebRequest.Create("http://code5.sendloop.com/api/v3/System.SystemDate.Get/json");
request.ContentType = "application/json; charset=utf-8";
string postData = "APIKey=xxxx-xxxxx-xxxxx-xxxxx-xxxxx";
request.Method = "POST";
ASCIIEncoding encoding = new ASCIIEncoding();
byte[] data = encoding.GetBytes(postData);
request.ContentLength = data.Length;
Stream newStream = request.GetRequestStream(); //open connection
newStream.Write(data, 0, data.Length); // Send the data.
newStream.Close();
string text;
var response = (HttpWebResponse)request.GetResponse();
using (var sr = new StreamReader(response.GetResponseStream()))
{
text = sr.ReadToEnd();
}
string userAuthenticationURI =
"https://maps.googleapis.com/maps/api/distancematrix/json?origins="+ originZip +
"&destinations="+ DestinationZip + "&units=imperial&language=en-
EN&sensor=false&key=Your API Key";
if (!string.IsNullOrEmpty(userAuthenticationURI))
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(userAuthenticationURI);
request.Method = "GET";
request.ContentType = "application/json";
WebResponse response = request.GetResponse();
var responseString = new
StreamReader(response.GetResponseStream()).ReadToEnd();
dynamic obj = JsonConvert.DeserializeObject(responseString);
}

This api has api_key,username and password.How can I access this api and getproduct details using c#.I tried like this
WebRequest request = WebRequest.Create(#"https://example.com/ProductAPI/api/V1/getproduct");
request.Method = "GET";
request.Headers.Add("api_key","5g13441f-6915-4a34-8a53-bcb4er88b554");
request.Headers["Authorization"] = "Basic" + Convert.ToBase64String(Encoding.Default.GetBytes("admin:123"));
request.ContentLength = 0;
request.ContentType = #"application/json; charset=utf-8";
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
string jsonResponse = string.Empty;
using (StreamReader sr = new StreamReader(response.GetResponseStream()))
{
jsonResponse = sr.ReadToEnd();
Console.WriteLine(jsonResponse);
Console.ReadLine();
}
But it show 401 unauthorized error.Pls help to solve this
I am trying to write a YouTube app for windows phone, and I stumbled upon some problems on the authentication side. For some reason the following code is not working properly,
string url = "https://accounts.google.com/o/oauth2/token?";
string postData = "code=" + str + "&client_id=*********.apps.googleusercontent.com&client_secret=*******&grant_type=authorization_code";
HttpWebRequest httpWReq = (HttpWebRequest)WebRequest.Create(url);
byte[] data = Encoding.Unicode.GetBytes(postData);
httpWReq.Method = "POST";
httpWReq.ContentType = "application/x-www-form-urlencoded";
using (Stream stream =await httpWReq.GetRequestStreamAsync())
stream.Write(data, 0, data.Length);
HttpWebResponse response =(HttpWebResponse)(await httpWReq.GetResponseAsync());
string responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
I am fairly new to HttpWebRequest so probably I missed something, although I am getting a response:
Bad Request
To be specific it says that grant_type is missing although I am pretty sure that it is not, I did everything according to the documentation. What am I doing wrong ?
This will probably fix it
parameters.Append("code=" + str);
parameters.Append("&client_id=*****.apps.googleusercontent.com");
parameters.Append("&client_secret=*****");
parameters.Append("&redirect_uri=urn:ietf:wg:oauth:2.0:oob:auto");
parameters.Append("&grant_type=authorization_code");
string p_params = parameters.ToString();
byte[] p_data_params = Encoding.UTF8.GetBytes(p_params);
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://accounts.google.com/o/oauth2/token");
request.Accept = "application/json";
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
Stream dataStream = await request.GetRequestStreamAsync();
dataStream.Write(p_data_params, 0, p_data_params.Length);
dataStream.Dispose();
HttpWebResponse response = (HttpWebResponse)await request.GetResponseAsync();
Stream responseStream = response.GetResponseStream();
StreamReader readStream = new StreamReader(responseStream, Encoding.UTF8);
string result = readStream.ReadToEnd();
Works fine for me.
I'm trying to login to this website here: https://freebitco.in/
So I set up a web request like so:
var request = (HttpWebRequest)WebRequest.Create("https://freebitco.in");
var postdata = "op=login&btc_address=BTCADDRESS&password=PASSWORD";
var data = Encoding.ASCII.GetBytes(postdata);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = data.Length; //1PkhThc9hCXpdvcThtwX3SzbfmTzDFxL1h:bigken <= BTC Login
using (var stream = request.GetRequestStream())
{
stream.Write(data, 0, data.Length);
}
var response = (HttpWebResponse)request.GetResponse();
var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
MessageBox.Show(responseString);
The messagebox returns to me nothing though, blank. I'm not sure why this is happening so I was hoping someone could shed some light on this? I've also tried using a Web Client, and it gave me the same result. Thank you guys.
EDIT: Here's the Fiddler Raw data: http://pastebin.com/WUEvq6D5
Edit 2: Tried encoding the POST data and now it returns the login page
Updated Code:
var request = (HttpWebRequest)WebRequest.Create("https://freebitco.in");

request.ContentLength = data.Length;
using (var stream = request.GetRequestStream())
{
stream.Write(data, 0, data.Length);
}
var response = (HttpWebResponse)request.GetResponse();
var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();

The only approach that seems to work for me is using HttpWebRequest. I found the answer here: .Net Google OAuth token WebRequest Bad Request Protocol Error If anyone knows of a way to get the Web Client implementation working please let me know! Thanks.
I'm trying to get the userID of a Facebook user, I already have the access_token and I use http request to do it. My simple problem is that : I want the user's id but my program just crash... I use WPF, C# Here is my little call :
var url = string.Format("https://graph.facebook.com/me?access_token=" + token + "&response_type=id");
var req = WebRequest.Create(url);
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
string postData = "'access_token='" + token;
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
var stream = req.GetRequestStream();
stream.Write(byteArray, 0, byteArray.Length);
stream.Close();
WebResponse response = req.GetResponse();
aTextBox.Text = ((HttpWebResponse)response).StatusDescription;
stream = response.GetResponseStream();
StreamReader reader = new StreamReader(stream);
Thanks!
Don't use Web Browser for this! You may use HttpWebRequest for that kind of things:
string url = "https://graph.facebook.com/me?access_token=" + token + "&response_type=id";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
HttpWebResponse response = (HttpWebResponse)request.GetResponse ();
Stream receiveStream = response.GetResponseStream ();
StreamReader readStream = new StreamReader(receiveStream, Encoding.UTF8);
string responseData = readStream.ReadToEnd();
