The lack of documentation on this subject coupled with the fact that I'm struggling with a learning curve on all fronts and making me really confused about where to start. I need to get this done using C# if possible. I apologize for the vagueness of this question, but I'm really lost. I would love links to comprehensive guides/references.
In my efforts to get this done, I've run into the following problems/questions:
I've created a web service using the otrs gui, with the operation CreateTicket, but requests via C# to my chosen namespace are returning 404 (not found). When I try to add a service reference or web reference with that namespace, I get the same error. However, when I plug that namespace into my browser as the url, it displays "customer.pl".
Can I send a soap request without adding the web service as a service reference in visual studio? Given the previous problem I'm having I can't do it that way. Would I just build the soap request string and write it to the web request's data stream with http://domain/rpc.pl as the uri?
If the answer to the previous question is yes... When trying the below code segment I get an internal server error (500) on the last line. However the header looks like a SOAP header which confuses me because I wouldn't have thought it got that far.
var document = new StringBuilder();
document.Append("<UserLogin>some user login</UserLogin>");
document.Append("<Password>some password</Password> ");
document.Append("<Ticket>");
document.Append("<Title>some title</Title> ");
document.Append("<CustomerUser>some customer user login</CustomerUser>");
document.Append("<Queue>some queue</Queue>");
document.Append("<State>some state</State>");
document.Append("<Priority>some priority</Priority>");
document.Append("</Ticket>");
document.Append("<Article>");
document.Append("<Subject>some subject</Subject>");
document.Append("<Body>some body</Body>");
document.Append("<ContentType>text/plain; charset=utf8</ContentType>");
document.Append("</Article>");
//var uri = new Uri("http://domain/injest");
var uri = new Uri("http://domain/rpc.pl");
var httpWebReq = (HttpWebRequest)WebRequest.Create(uri);
var bytePostData = Encoding.UTF8.GetBytes(document.ToString());
httpWebReq.Timeout = 5 * 1000;
httpWebReq.Method = "POST";
httpWebReq.ContentLength = bytePostData.Length;
httpWebReq.ContentType = "text/xml;charset=utf-8";
//httpWebReq.TransferEncoding=
//httpWebReq.ContentType = "application/xml";
//httpWebReq.Accept = "application/xml";
var dataStream = httpWebReq.GetRequestStream();
dataStream.Write(bytePostData, 0, bytePostData.Length);
dataStream.Close();
var httpWebResponse = (HttpWebResponse)httpWebReq.GetResponse();
Even if all you can offer is where to start, it would help me to know how to proceed, as I'm stumped.
You're using the rpc.pl endpoint which is part of the 'old' RPC-style interface.
You mention you added the web service via the GUI which means you're using the 'new' Generic Interface, which is indeed much easier from .Net.
The address of the endpoint is /otrs/nph-genericinterface.pl/Webservice/GenericTicketConnector or whatever you have called the web service in the admin section.

I'm trying to get the number of followers of a company on Linked in.
I use this code:
HttpWebRequest request = WebRequest.Create("http://api.linkedin.com/v1/companies/?id=SomeCompanyID:(num-followers)") as HttpWebRequest;
request.Method = "Get";
request.Credentials = new NetworkCredential("MyAppClientID", "MyAppClientSecret");
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse) // I'm getting "(401) Unauthorized" exception at this line.
{
StreamReader reader = new StreamReader(response.GetResponseStream());
string result = reader.ReadToEnd();
System.IO.File.WriteAllText(#"WriteText.txt", result);
Console.WriteLine(reader.ReadToEnd());
}
I'm not sure about my syntax and the way I provide credentials, but I don't know how to do so correctly, and documentation is not clear at this point.
Your help is appreciated.
It looks like you haven't registered your application or more accurately you haven't updated the code sample with your own ClientKey and Secret value.
You obtain them from https://www.linkedin.com/developer/apps/
You can also find more information about it here https://developer.linkedin.com/support/faq
Where can I find my API key?
Click on the My Apps link in the top navigation menu to manage your
LinkedIn applications.
From here, you can create a new application if you don't already have
one or view the details of your existing applications. You will find
your Client ID (otherwise known as API Key/ID or Consumer Key/ID)
listed in the "Authentication" side nav link, underneath the header
"Authentication Keys".
Alternatively, you may be using an old format of Rest API call, accoring to this page (https://developer.linkedin.com/docs/company-pages), the new format is as follows

I spent all day in figuring out how to request Walmart v3. I propose you the following two steps:
Use Walmart signer in order to generate signed token.
You will need to use HttpWebRequest for getting response from Walmart in a way similar to what is described here.
I have not been able to get this to work natively in C#, but I do have a work around.
The Java SDK can successfully submit multi-part requests to Walmart. I wrote a wrapper around the SDK functions that can accept basic command line input to read a text file and send the appropriate call with attached files. From here, you can just call the .jar file (I do it via dynamically generated batch file) from your C# program and receive responses back via text file. This is a sub-optimal system, but it works reliably and when the choice was between updating inventory on 2000 items every day and using some dirty code, I went with the Java wrapper method. This will be replaced as soon as the C# SDK comes out, but I believe this is one of the reasons why the C# SDK may be being delayed.
This solution was used, only after spending about a week trying to get boundaries / streams / attachments to work in C# and having zero success. Cases were also submitted to walmart and I was able to work with some of their top tier engineering support staff and this problem completely stumped them. I was able to trace the Java SDK execution all the way down to a built in Maven / Java function that constructed the web request so there's something under the hood that Java is doing with a multi-part request that isn't immediately clear in C#.

Actual Scenario: I am working on a site (ASP.Net using C#) where the system will have 3 different subscription plans i.e. monthly, quarterly and yearly. All the subscription plans have their own cost and pricing. Now, if the system/admin wants to give any discounts to any subscribed user (regardless of subscription plan) on their on-going subscription based on some business logic (for example, for some user it may be $4 and for other it may be $25). How can I achieve this goal. I tried PayPal and Recurly, but stuck in-between.
++++++++++++++
I have to create a coupon and redeem the same using Recurly dynamically in C#. But, as per the code mentioned in "https://docs.recurly.com/api/v1/subscription-plans", we have to use Recurly API v2, but we don't have the code to create and redeem the coupon. So, please help me on how can I create coupons and redeem the same.
When we are using below code in mentioned URL "Recurly PUT request working but returning server error", it causes error while getting response.
uri = "https://" + subdomain + ".recurly.com/v2/subscriptions/" + uuid + "/reactivate";
try
{
string xml = "<subscription><timeframe>now</timeframe></subscription>"; //also tried with blank string.
byte[] arr = System.Text.Encoding.UTF8.GetBytes(xml);
HttpWebRequest renewRequest = (HttpWebRequest)WebRequest.Create(uri);
renewRequest.Headers.Add("Authorization", "Basic " + encodeB64);
renewRequest.Method = "PUT";
renewRequest.ContentType = "text/XML";
renewRequest.ContentLength = arr.Length;
Stream datastream = renewRequest.GetRequestStream();
datastream.Write(arr, 0, arr.Length);
datastream.Close();
HttpWebResponse renewResponse = (HttpWebResponse)renewRequest.GetResponse();
}
Looking for kind response and help...
We (recurly.com) just made available a release candidate of an all new API client for C# compatible with Recurly APIv2 that we highly recommend using. The client API is stable and this release will shortly become the final release pending new show-stopping bugs.
Here's how to get started using it.
Be sure set up your configuration.
Here's how to create a coupon.
Here's how to redeem coupons.
More examples are available here.

I am trying to send an xml document to a REST web service. Using a tool like Poster, the call works fine (With the xml in the body of the "content"), but in my code, I get error 503 server unavailable.
Link to Poster: https://addons.mozilla.org/en-US/firefox/addon/poster/
My code is as follows (this is a test-harness so no error handling etc):
string s = "";
using (StreamReader sr = new StreamReader(#"c:\users\dev.admin\documents\visual studio 2010\Projects\WindowsFormsApplication2\WindowsFormsApplication2\XMLFile1.xml"))
{
s = sr.ReadToEnd();
}
string url = FULL_URL_WITH_PARAMETERS; // SAME URL AS USED IN POSTER
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
request.Method = "POST";
request.ContentType = "text/xml;charset=UTF-8";
string data = s;
Stream postStream = null;
using (StreamWriter requestStream = new StreamWriter(request.GetRequestStream()))
{
requestStream.Write(data);
}
HttpWebResponse pervasiveResponse = (HttpWebResponse)request.GetResponse();
StreamReader sr1 = new StreamReader(pervasiveResponse.GetResponseStream(), System.Text.Encoding.Default);
string backstr = sr1.ReadToEnd();
}
else
{
throw new ArgumentNullException();

REST Starter Kit? WCF Web API (Glenn Block's project, now part of AppFabric int he 4.5 time frame? (although I believe there will be a standalone))? Roll your own joint?
Regardless, I think working with binary is the correct method to go. For that reason, I would start with something like this article. Not because I tried the code and think it is a great article, but merely because the article shows sending XML and I don't have time to find the client I wrote a few months ago. ;-)
If I can break free long enough to find my code, I will post a sample.
Oh, another tool you should look at is SoapUI. No, it is not just for testing SOAP, as it supports REST (and other methodologies) as well as SOAP. One nice benefit of using SoapUI is the ability to move the tests over to LoadUI and stress testing a service. If you are merely consuming services, it might not have the greatest value, of course.
I am working on a WP7 application. If an error happens, I want to log the error back to my server. To handle this, I have created a WCF service operation. I want this operation to be REST ful so that I can later use it with iPhone and Android apps. Because I'm writing information to the database, I thought the POST method would be best. For this reason, I'm using WebInvoke. To do this, I'm using the following code:
[OperationContract]
[WebInvoke(UriTemplate = "/LogError/{message}/{stackTrace}", ResponseFormat = WebMessageFormat.Json)]
public void LogError(string message, string stackTrace)
{
// Write info to the database
}
From my WP7 app, I want to call this operaiton via a WebClient. My question is, how do I do that? I don't understand how to call the LogError operation and pass along the required data via the WebClient.
Thank you for your help!
If I am getting your Service method correctly, that method is not a POST method. You can just call that with a WebClient
WebClient wc = new WebClient()
Uri uri = new Uri("http://yourUri/LogError/ABC/XYZ"); //ABC is your message and XYZ is your stacktrace string.
wc.DownloadStringAsync(uri);
Or if you are thinking about real HTTP 'POST' then below might help.
You can use HttpWebRequest to do a POST on to any service which is accepting POST
This link may be helpful - WCF REST POST XML - The remote server returned an error: (400) Bad Request
Something along the lines:
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://serveraddress/LogError/{message}/{stackTrace}");
If you would want to send additional information later on, you can do so with:
request.Method = "POST";
request.BeginGetRequestStream(new AsyncCallback(ExecuteAction), request);
And have a callback:
void ExecuteAction(IAsyncResult result)
{
HttpWebRequest request = (HttpWebRequest)result.AsyncState;
using (Stream s = request.EndGetRequestStream(result))
{
s.Write(data, 0, data.Length);
}
}
If there is a specific string response from the service, you might as well include the data in the WebClient and use DownloadStringAsync to get the response data.
For starters, I found a website that should help you get started with calling the service from WP7.
Try this and let me know what you think
Have a look at this post http://blog.ike.to/2011/02/02/wp7-application-crash-reporter/
It sounds like it will pretty much do what you need already, although you might want to tweak it to suit your own service interface.
