Getting Attachments in Zoho Desk via API

Is there a way to get attachments into Zoho Desk via an API?      We have a process by which a zoho survey gets sent to the user as a link in a notification.    The survey has several upload fields where they can upload pdf documents.    I've created a Zoho Flow that posts the information back to the Zoho Desk ticket once the survey has been filled out.    I can't seem to figure out how to bring the attachments over.    Ideas?
