C# Send A SMS Text Message Programmatically Using Clickatell HTTP API

I would start off by heading here to better understand the Clickatell HTTP API: https://www.clickatell.com/apis-scripts/apis/http-s/. If you are interested they allow you 10 free text messages to try it out before you buy a package. Just sign up for an account and create your HTTP API and use your information to populate the snippet below.

For a particular project I am using this API to send out texts for verification purposes. I am using my method inside of a web service to send the information about a user as well as their pre-generated pin. Of course it is a lot different in my project but I am providing the bare bones below.

If you are a skimmer and you skipped reading anything I said above then here you go:

Code for MyWebRequest class:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Net;
using System.IO;
using System.Text;
using System.Configuration;

namespace CustomWebServices
public class MyWebRequest
private WebRequest request;
private Stream dataStream;

private string status;

public String Status
return status;
status = value;

public MyWebRequest(string url)
// Create a request using a URL that can receive a post.

request = WebRequest.Create(url);

public MyWebRequest(string url, string method)
: this(url)

if (method.Equals("GET") || method.Equals("POST"))
// Set the Method property of the request to POST.
request.Method = method;
throw new Exception("Invalid Method Type");

public MyWebRequest(string url, string method, string data)
: this(url, method)

// Create POST data and convert it to a byte array.
string postData = data;
byte[] byteArray = Encoding.UTF8.GetBytes(postData);

// Set the ContentType property of the WebRequest.
request.ContentType = "application/x-www-form-urlencoded";

// Set the ContentLength property of the WebRequest.
request.ContentLength = byteArray.Length;

// Get the request stream.
dataStream = request.GetRequestStream();

// Write the data to the request stream.
dataStream.Write(byteArray, 0, byteArray.Length);

// Close the Stream object.


public string GetResponse()
// Get the original response.
WebResponse response = request.GetResponse();

this.Status = ((HttpWebResponse)response).StatusDescription;

// Get the stream containing all content returned by the requested server.
dataStream = response.GetResponseStream();

// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader(dataStream);

// Read the content fully up to the end.
string responseFromServer = reader.ReadToEnd();

// Clean up the streams.

return responseFromServer;

And now the code for the method itself:

public string SendText(string mobile, string pin)
// Make sure to add the country code to ensure the text goes through
string phoneCheck = "";
if (mobile.Length == 10)
phoneCheck = "1" + mobile;
// Clickatell settings
string textmessage = "Your verification pin is " + pin;
string parameters = "";
parameters = "user=yourclickatellusername";
parameters = parameters + "&password=yourclickatellpassword";
parameters = parameters + "&api_id=youruniqueclickatellhttpapiid";
parameters = parameters + "&to=" + phoneCheck;
parameters = parameters + "&text=" + textmessage;
parameters = parameters + "&mo=1";
parameters = parameters + "&from=15558675309";
MyWebRequest myRequest = new MyWebRequest("<a href="http://api.clickatell.com/http/sendmsg">http://api.clickatell.com/http/sendmsg</a>", "POST", parameters);
} // SendText

* Note: If you put this call on a server that will require a proxy then add it to your MyWebRequest class

C#, SharePoint, Web Service

Add An Item To A Custom SharePoint List Using Batch XML With A Web Service (C#)

If you have multiple active directory environments and SharePoint instances in both of those environments then you will understand why I posted this.

I received a requirement that while users from a separate domain and SharePoint instance would need to fill out a form on their SharePoint and have the form submission be sent to the other SharePoint instance (on the other domain). This was because they did not want to mix and mingle with forest trusting or having users to have two separate AD accounts to manage the information. Say what?!

After some initial discovery I had reached a couple quick conclusions:

– SharePoints on different domains do not talk well to each other without trust

– Using the built-in lists service on SharePoint has to be done on the server itself unless you are going to have an instance stood up somewhere on the same domain that has all the required SharePoint dlls to be referenced

All being said, here is an example of what I used as a web service I placed on the SharePoint server that calls the lists web service doing a list add using batch XML:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Client;
using Microsoft.SharePoint.Administration;
using Microsoft.SharePoint.Administration.Claims;
using Microsoft.SharePoint.WebControls;

namespace CopyOverItemFromOtherSP

public string CopyOverFromOtherDomain(string userName, string Name, string userEmail,
string userPhone, string listColumn1, string listColumn2, string listColumn3,
string Comments)
Boolean done = false;

/* Declare and initialize a variable for the Lists Web service. */
sitesWebServiceLists.Lists listService = new sitesWebServiceLists.Lists();

/* Authenticate the current user by passing their default credentials to the Web service from the system credential cache. */
listService.Credentials = System.Net.CredentialCache.DefaultCredentials;

/* Set the Url property of the service for the path to a subsite. */
// Change the web reference URL on the sitesWebServiceLists web service reference to be the address
// that you are wanting to used based on the environment that you want to write to
listService.Url = "<a href="#">http://sharepointtocopyitemto/_vti_bin/Lists.asmx</a>";

/* Get Name attribute values (GUIDs) for list and view. */
System.Xml.XmlNode ndListView = listService.GetListAndView("NameOfSharePointList", "");
string strListID = ndListView.ChildNodes[0].Attributes["Name"].Value;
string strViewID = ndListView.ChildNodes[1].Attributes["Name"].Value;

/* Create an XmlDocument object and construct a Batch element and its
attributes. Note that an empty ViewName parameter causes the method to use the default view. */
System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
System.Xml.XmlElement batchElement = doc.CreateElement("Batch");
batchElement.SetAttribute("OnError", "Continue");
batchElement.SetAttribute("ListVersion", "1");
batchElement.SetAttribute("ViewName", strViewID);

/* Specify methods for the batch post using CAML. To update or delete,
specify the ID of the item, and to update or add, specify
the value to place in the specified column. */
batchElement.InnerXml = "<Method ID='1' Cmd='New'>" +
"<Field Name='ID'>New</Field>" +
"<Field Name='Title'>" + userName.ToString() + "</Field>" +
"<Field Name='Name'>" + Name.ToString() + "</Field>" +
"<Field Name='userEmail'>" + userEmail.ToString() + "</Field>" +
"<Field Name='userPhone'>" + userPhone.ToString() + "</Field>" +
"<Field Name='listColumn1'>" + listColumn1.ToString() + "</Field>" +
"<Field Name='listColumn2'>" + listColumn2.ToString() + "</Field>" +
"<Field Name='listColumn3'>" + listColumn3.ToString() + "</Field>" +
"<Field Name='Comments'>" + Comments.ToString() + "</Field>" +

/* Update list items. This example uses the list GUID, which is recommended,
but the list display name will also work. */
listService.UpdateListItems(strListID, batchElement);
done = true;

if (done == true)
return done.ToString();
return done.ToString();
