Instructions

Create a new Console Application project and add a web reference

Copy the entire code below, delete anything written in your application and paste the code there
Replace "MyUsername" and "MyPassword" with your PostalMethods user details
Replace "ID" with the LetterID for which you would like to get the status
Start your application. If the response is -3000, you will see the status report. If the response is any other number, check the Web Service Status Codes section.

using System.IO;
 
class Module1
{
    public void Main()
    {
 
        com.postalmethods.api.PostalWSSimple objPM = new com.postalmethods.api.PostalWSSimple();
        com.postalmethods.api.GetLetterStatusResult objResult;
 
        //
        // Invoke the GetLetterStatus method
        //
        objResult = objPM.GetLetterStatus("MyUsername", "MyPassword", ID);
 
        //
        // Check response status
        //
        if (objResult.ResultCode == -3000)
        {
            //
            // -3000 means that the data was successfully retrieved.
            //
            Console.WriteLine("Last update time: {0}", objResult.LastUpdateTime);
            Console.WriteLine("Status: {0}", objResult.Status);
        }
        else
        {
            //
            // A value less than -3000 means an error occurred.
            // See the PostalMethods Status Codes: http://www.postalmethods.com/statuscodes.
            //
            Console.WriteLine("Error is:" + objResult.ResultCode);
        }
 
        // In debug mode, the following lines prevent your console application from closing automatically upon termination
        Console.WriteLine("Hit ENTER to terminate application");
        Console.ReadLine();
