Add support for File Upload in FME Flow Automation Apps

I'm surprised this hasn't been implemented already. It seems like it would be straight forward. Is there any workaround that allows us to upload a .shp file into a user parameter within a custom attribute in the fme automations?

I also stumbled just over this very weird limitation. After i added a manual Trigger to the automation, you can add a manual parameter of type “Choose File”.

This even already provides a UI for file selection in a Flow Automation App. But after struggeling with assigning Access rights to the app token to the File Upload Service and some Resource folders, i noticed that this manual file selection is only able to select a already existing file (and this is also stated in the doc).

I do not see any reason, why at this point the temporary file upload like with a Workspace App with file input should not be possible.

This would be a great help to enable the running of automations triggered by a user upload, where more than one workspace needs to run and we do not need or want to store the file; this includes where there are data sovereignty concerns i.e. data cannot be permanently stored (or stored outside of runtime) in the Flow server’s location.  In our case for Flow Hosted these things are mostly or all pertinent. 

This is currently requiring a look back at the old notifications workflow.

As we have automation parameters already, it would seem logical to expose these to the app where desired.

Just updating that this is not possible in 2026.1, automation apps only allow file uploads from the resources folder on Flow and not from an external source e.g. file browser on a user’s machine.
