ColdFusion: Send A Letter With SendLetterV2()


  1. Make sure your ColdFusion environment is ready and create a new CFM page.
  2. Copy the entire code below and paste the code in the CFM page.
  3. Replace the values of the cfset lines with your details:
    • Replace MyUsername and MyPassword with your PostalMethods user details.
    • Replace MyDescription with your own text to help you identify this letter in your activity log (optional).
    • Replace absolutePathToFile with a path to your test PDF file. Remember, for method SendLetterV2 you must use a document where the recipient's address already appears so it will show through the envelope window. You can use one of our Sample Letter Documents.
    • MyWorkMode determines if your letter will be sent as Production, Development or will use your user's default Work Mode setting. Read more about Production and Development Work Modes.
  4. Start your application. It will start, encode your document as Base64 and send a letter to the PostalMethods SendLetterV2 Web Service method. If the response is a positive number, you will be able to see your letter in the PostalMethods Control Panel.
  5. If the response is negative number, check the Web Service Status Codes section.

That's it - you have successfully sent a letter to PostalMethods. Congratulations.
