I'm trying to use the check_eligibility call from the eBay Post-Order API in C# very unsuccessfully. Every time I get a bad response. Here is one way I've tried:
string url = "https://api.ebay.com/post-order/v2/cancellation/check_eligibility";
HttpWebRequest cancelOrderRequest = (HttpWebRequest)WebRequest.Create(url);
cancelOrderRequest.Headers.Add("Authorization", "TOKEN " + AuthToken);
cancelOrderRequest.ContentType = "application/json";
cancelOrderRequest.Accept = "application/json";
cancelOrderRequest.Headers.Add("X-EBAY-C-MARKETPLACE-ID", "EBAY_US");
cancelOrderRequest.Headers.Add("legacyOrderId", ebayFullOrderId);
cancelOrderRequest.Method = "POST";
HttpWebResponse response = (HttpWebResponse)cancelOrderRequest.GetResponse();
And here is another way I've tried:
string url = "https://api.ebay.com/post-order/v2/cancellation/check_eligibility";
var httpWebRequest = (HttpWebRequest)WebRequest.Create(url);
httpWebRequest.ContentType = "application/json";
httpWebRequest.Method = "POST";
httpWebRequest.Headers.Add("Authorization", "TOKEN " + AuthToken);
httpWebRequest.Headers.Add("X-EBAY-C-MARKETPLACE-ID", "EBAY_US");
httpWebRequest.Accept = "application/json";
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
string json = "{\"legacyOrderId\":\"###-###\"";
streamWriter.Write(json);
streamWriter.Flush();
streamWriter.Close();
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var result = streamReader.ReadToEnd();
}
Regardless of which way I try both came back with the same message, "The remote server returned an error: (400) Bad Request." If anyone could point me in the right direction I'd greatly appreciate it. Thanks.
My second code example ended up being the correct way to solve my problem. What I realized was my json was slightly off. I was missing the extra } at the end. The below updated json syntax fixed my problem going with the code from my second example.
var json = "{\"legacyOrderId\":\"" + ebayFullOrderId + "\"}";
Please try this code:
private void MakeRequests()
{
HttpWebResponse response;
if (RequestEbay(out response))
{
response.Close();
}
}
private bool RequestEbay(out HttpWebResponse response)
{
response = null;
try
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://api.ebay.com/ws/api.dll");
request.Headers.Add("X-EBAY-API-SITEID", #"0");
request.Headers.Add("X-EBAY-API-COMPATIBILITY-LEVEL", #"967");
request.Headers.Add("X-EBAY-API-CALL-NAME", #"GetOrders");
request.Method = "POST";
request.ServicePoint.Expect100Continue = false;
string body = #"<?xml version=""1.0"" encoding=""utf-8""?>
<GetOrdersRequest xmlns=""urn:ebay:apis:eBLBaseComponents"">

</GetOrdersRequest>";
byte[] postBytes = System.Text.Encoding.UTF8.GetBytes(body);
request.ContentLength = postBytes.Length;
Stream stream = request.GetRequestStream();
stream.Write(postBytes, 0, postBytes.Length);
stream.Close();
response = (HttpWebResponse)request.GetResponse();
}
catch (WebException e)
{
if (e.Status == WebExceptionStatus.ProtocolError) response = (HttpWebResponse)e.Response;
else return false;
}
catch (Exception)
{
if(response != null) response.Close();
return false;
}
return true;

I am using Postman to get the response from rest end point, and if I pass wrong data I am getting 400 exception which is very correct as per the logic.
But if I try to call the same web request from C# code(with same wrong parameter), I am getting exception but not the same as I am getting in Postman tool.
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
var httpWebRequest = (HttpWebRequest)WebRequest.Create("https://apiurl");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Headers.Add("Authorization", "Bearer " + token);
httpWebRequest.Method = "POST";
httpWebRequest.UserAgent = ".Net application";
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
string json = JsonConvert.SerializeObject(obj);//obj is parameter
streamWriter.Write(json);
}
try
{
HttpWebResponse httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var result = streamReader.ReadToEnd();
}
}
catch (WebException e)
{
}
Can I know why I am getting errors differently from postman and C# code
Regards
Anand
Added below code in the exception block and it gave me the same response as Postman
catch(WebException ex)
{
string message = ex.Message;
WebResponse errorResponse = ex.Response;
if (errorResponse != null)
{
using (Stream responseStream = errorResponse.GetResponseStream())
{
StreamReader reader = new StreamReader(responseStream, Encoding.GetEncoding("utf-8"));
message = reader.ReadToEnd();
}
}
}
I am getting '(400) Bad Request.' when I try complete authenticate against an ALM REST API, the first part (authentication) is successful) and I get the LWSSO_COOKIE_KEY, but site-session always fails with a 400 error code.
What am I doing wrong please... very confused!
// Authentication XML : 0 = User, 1 = Password
private const string AuthenticationXML = #"<alm-authentication>" +
"<user>{0}</user><password>{1}</password></alm-authentication>";
baseRequestURL = settings.QualityCentreURL + "/qcbin/";
Authentication is done first (and is successful) :
string authRequest = baseRequestURL + "authentication-point/alm-authenticate";
HttpWebRequest myauthrequest = (HttpWebRequest)WebRequest.Create(authRequest);
string xml = String.Format(AuthenticationXML, qcSettings.Username, qcSettings.Password);
byte[] Requestbytes = Encoding.UTF8.GetBytes(xml);
myauthrequest.Method = "POST";
myauthrequest.ContentType = "application/xml";
myauthrequest.ContentLength = Requestbytes.Length;
myauthrequest.Accept = "application/xml";
Stream RequestStr = myauthrequest.GetRequestStream();
RequestStr.Write(Requestbytes, 0, Requestbytes.Length);
RequestStr.Close();
HttpWebResponse myauthres = (HttpWebResponse)myauthrequest.GetResponse();
authenticationCookie = myauthres.Headers.Get("Set-Cookie");
The Site-Session code is :
public void GetSiteSession()
{
// Creat the web request fore site-session.
string request = baseRequestURL + "rest/site-session";
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(request);
string xml = String.Empty;
byte[] requestbytes = Encoding.UTF8.GetBytes(xml);
// Update the attributes before sending.
webRequest.Method = "POST";
webRequest.ContentType = "application/xml";
webRequest.Accept = "application/xml";
webRequest.Headers.Set(HttpRequestHeader.Cookie, authenticationCookie);
try
{
Stream requestStream = webRequest.GetRequestStream();
requestStream.Write(requestbytes, 0, requestbytes.Length);
requestStream.Close();
HttpWebResponse webRequestResponse = (HttpWebResponse)webRequest.GetResponse();
Stream responseStream = webRequestResponse.GetResponseStream();
XDocument doc = XDocument.Load(responseStream);
}
catch (System.Net.WebException except)
{
Console.WriteLine(except.Message);
}
}
I have tried cutting ;Path=/;HTTPOnly from LWSSO_COOKIE_KEY as per this question, but to no avail.
The API reference I found(here) seems to be a big vague or, possibly that I haven't understood it... :P
Apologies, it seems that with 12.53 I should have been using 'api/authentication/sign-in'
string requestURL = baseRequestURL + "api/authentication/sign-in";
try
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(requestURL);
var credentials = String.Format("{0}:{1}", qcSettings.Username, qcSettings.Password);
request.CookieContainer = authenticationCookieContainer;
request.Headers.Set(HttpRequestHeader.Authorization, "Basic " + Convert.ToBase64String(Encoding.UTF8.GetBytes(credentials)));
var authResponse = request.GetResponse();
errorString = String.Empty;
}
catch (System.Net.WebException except)
{
errorString = except.Message;
return false;
}
errorString = String.Empty;
return true;

I'm trying to log in into iCloud using a Json Post request in C#. Before trying to implement the code I was studying a little bit the iCloud requests using Chrome Console and using an Ad-on to replicate the requests in order to obtain the same result of the website.
First of All I checked the request directly from iCloud website:
And this is the response:
{
"serviceErrors" : [ {
"code" : "-20101",
"message" : "Il tuo ID Apple o la password non sono corretti."
} ]
}
Using "Advance REST Client" ad Chrome plugin to replicate the request I ve tried the same Json request to the same Url. But I get Empty response:
I Also tried to copy and paste the whole Header (All the settings) and than send the request but the response is the same:
Anyone has an Advice?
UPDATE: I tried to implement A Json request through c# program:
var httpWebRequest = (HttpWebRequest)WebRequest.Create("https://idmsa.apple.com/appleauth/auth/signin");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Method = "POST";
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
string json = "{accountName: \"briesanji #gmail.com\", password: \"testPassword\", rememberMe: false, trustTokens: []}";
streamWriter.Write(json);
streamWriter.Flush();
streamWriter.Close();
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var result = streamReader.ReadToEnd();
}
The problem is that Execution breaks when the
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
is hit and it gives me this error: System.Net.WebException: 'Error Remote Server: (400) Request not valid.'
UPDATE: I solved in this way:
void POST(string url, string jsonContent)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Method = "POST";
System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding();
Byte[] byteArray = encoding.GetBytes(jsonContent);
request.ContentLength = byteArray.Length;
request.ContentType = #"application/json";
using (Stream dataStream = request.GetRequestStream())
{
dataStream.Write(byteArray, 0, byteArray.Length);
}
long length = 0;
try
{
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
{
length = response.ContentLength;
}
}
catch (WebException ex)
{
// Log exception and throw as for GET example above
}
}
string GET(string url)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
try
{
WebResponse response = request.GetResponse();
using (Stream responseStream = response.GetResponseStream())
{
StreamReader reader = new StreamReader(responseStream, Encoding.UTF8);
return reader.ReadToEnd();
}
}
catch (WebException ex)
{
WebResponse errorResponse = ex.Response;
using (Stream responseStream = errorResponse.GetResponseStream())
{
StreamReader reader = new StreamReader(responseStream, Encoding.GetEncoding("utf-8"));
String errorText = reader.ReadToEnd();
// log errorText
}
throw;
}
}
Anyways I tested also the Answer and it was good to.. So I check it as valid thanks.
With this i dont get any error and the response content of the second request just tells me that there were too many failed logins for the test account...

anyone can help me? I already read a series of articles that unfortunately did not help me. Thanks a lot!
Your request maybe true but server-side doesn't know how to process your data. Maybe parameters which are sent fault. Please check your server-side so end-point.
I'm trying to call http://genderize.io/ , but i'm getting an error from .NET saying:
{"You must provide a request body if you set ContentLength>0 or SendChunked==true. Do this by calling [Begin]GetRequestStream before [Begin]GetResponse."}
How would I call this web service "http://api.genderize.io/?name=peter" from C# and get a JSON string back?
HttpWebRequest request;
string postData = "name=peter"
URL = "http://api.genderize.io/?"
Uri uri = new Uri(URL + postData);
request = (HttpWebRequest)WebRequest.Create(uri);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = postData.Length;
request.AllowAutoRedirect = true;
UTF8Encoding enc = new UTF8Encoding();
string result = string.Empty;
HttpWebResponse Response;
try
{
using (Response = (HttpWebResponse)request.GetResponse())
{
using (Stream responseStream = Response.GetResponseStream())
{
using (StreamReader readStream = new StreamReader(responseStream, Encoding.UTF8))
{
return readStream.ReadToEnd();
}
}
}
}
catch (Exception ex)
{
Debug.WriteLine("Error: " + ex.Message);
throw ex;
}
You are making the call to the service using POST method, reading through the comments area in http://genderize.io/ the author states that only GET method requests are allowed.
Stroemgren: Yes, this is confirmed. Only HTTP GET request are allowed.
This answer probably would be better as a comment, but I don't have enough reputation :(
