C#: Get The Generated Letter with GetPDF()

Instructions

  1. Create a new Console Application project and add a web reference.
  2. Copy the entire code below, delete anything written in your application and paste the code there.
  3. Replace the values of the Const lines with your details:
    • Replace MyUsername and MyPassword with your PostalMethods user details.
    • Replace “ID” with the LetterID for which you would like to get the PDF.
  4. 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.
