This example uses a Document Template to generate a PDF or HTML document, and then attaches the document to the current case.

In outline, the process is:

  1. Get the record ID from the incoming method parameters.
  2. Use the generateDocument API to create a PDF (or HTML) document from an existing template.
  3. Use the getDocument API to retrieve it, in the form of a PlatformFileBean.
  4. Use the addRecord API to attach the document to the case.
