I am building a web application in ASP.NET using C#.NET which sends a SMS using clickatell.
I am trying unsuccessfully to receive a status back from clickatell by creating a CallBack Page called ClickatellCallBack.aspx Here is the codebehind of the Page:
public partial class ClickatellCallBack : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
// Retrieve the values from the QueryString.
string apiID = Request.QueryString["api_id"];
string from = Request.QueryString["from"];
string to = Request.QueryString["to"];
string timestamp = Request.QueryString["timestamp"];
string apiMsgId = Request.QueryString["apiMsgId"];
string cliMsgId = Request.QueryString["cliMsgId"];
string status = Request.QueryString["status"];
string charge = Request.QueryString["charge"];
// Insert the SMS Status values into the database.
int smsStatusID = SMSManager.InsertSMSStatus(apiID, from, to,
timestamp, apiMsgId, cliMsgId, status, charge);
}
}
Basically, this Page retrieves the Query String values sent from clickatell and inserts them into a database table.
I have registered the following Callback URL: http://www.mydomain.com/ClickatellCallBack.aspx with clickatell and selected the Callback Type: HTTP GET
In my 'sendmsg' command I set delivery acknowledgement and callback request as follows: deliv_ack=1 and callback=3
The only problem being that nothing appears to be happening. The CallBack URL doesn't appear to be reached by clickatell.
Am I missing something? Am I doing something wrong. Do I need to implement this Callback URL using something other than an ASP.NET Page? Is there some clickatell setting I'm missing?
Any help would be greatly appreciated.
Regards
Walter
