C# Fax – Cancel a Submitted Fax
Download the C# fax API zip file.
This code sample uses the CancelFax method to cancel a previously-submitted (outbound) C# fax. Using CancelFax only effects faxes waiting to be sent (with the status codes: -1 Preprocessing, -2 Ready, or -3 Pending Retry), and not faxes that are being actively transmitted.
In the C# fax code snippet below, an inbound fax is cancelled, and a check is performed to see if the cancellation succeeded:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace CancelFax
{
class Program
{
static void Main(string[] args)
{
string username = "";
string password = "";
int transactionID = 546585833;
interfax.InterFax interfaxWebServiceOutbound = new interfax.InterFax();
long resultStatus = interfaxWebServiceOutbound.CancelFax(username, password, transactionID);
if (resultStatus == 0)
{
Console.WriteLine(string.Format("Cancelled TID {0}.", transactionID));
}
else
{
Console.WriteLine(string.Format("Failed with error code {0}.", resultStatus));
}
Console.ReadLine(); // use this to keep console open (waiting for keypress) after it is finished
}
}
}
