Are you trying to pass a file through a nintex automation cloud (nac) workflow to something? And if so where does the file start and need to end? Sharepoint online or sharepoint on premise?

Example: user uses file upload control on a nac start event form and workflow stores it in a sharepoint online library or attachment on a sharepoint online list item.

Hi @brandiwoodson 

Just to a network drive / file share on-premise.

This is for a school where the student information management system has a method to ‘watch’ a file share and any files placed into the folder are imported into the application against the student record.

I’m running into an issue where the Nintex Gateway product does not support file variables through any of it’s connectors (SharePoint On-premise, SQL On-Premise or Web Service)

Understood. I am of no help to you; we work with NAC & SharePoint Online (SPO) and just finished migrating from SharePoint on premise (SPOP) to SPO so I haven’t had a need to connect to SPOP through NAC.

Hope someone else is able to provide you with support on this thread. 

I’m using a process similar to your “pretty ugly” method. Files get sent to a third party service that can host a file then we have an internal process that runs every so often to download applicable files. 

I’m not sure if this would work, but I know Nintex has a “NWC Toolkit” connector here: https://gallery.nintex.com/t/toolkit-for-nwc

I’ve not used it, but it looks like it provides the ability to encode/decode files to base64 strings.  You could possibly use that to encode a file to a base64 string, pass that string through the gateway to something internal, where a script could decode the string back to the original file format… maybe?
