Convert Floe output to PDF

There are various tools available to convert HTML to PDF, and we have tested Floe with 3:

  •  HTMLPDFAPI
  • PDFCROWD
  • HTML2PDFROCKET

The approach for all three providers is the same:

Set up an SM59 connection to the service

Register for the service to get the username and password key.

This sample function shows how to invoke the services (note hard-coded passwords to be stored elsewhere)

The function can be called from a custom trigger program.  In this example we call Floe to generate the HTML, then call the function to convert to PDF, and then call Floe once again, adding the generated PDF as an attachment.
