Steps to Convert MHT to PDF using C# RESTful Service

  1. Instantiate the PdfApi service with the Client key and secret to change MHT to PDF
  2. Read the source MHT file into a memory stream
  3. Upload the memory stream to the Cloud storage by assigning a unique name
  4. Call the GetMhtInStorageToPdf() method to transform the uploaded MHT file into a PDF file
  5. Parse the API response to retrieve the resultant PDF file
  6. Save the returned stream as a PDF file on the disk

These steps define the process of exporting a file from MHT format to PDF using C# REST Interface. Commence the process by uploading the source MHT file to the Cloud storage and calling the GetMhtInStorageToPdf() method to convert it to a PDF in the Cloud.
