File uploads

You can find the 'Upload files' flow function in the flow function marketplace.

To use it you need:

1. A file object or a list of file objects. For example Take photo and Pick files flow functions output such objects.
2. Use a formula binding with the Upload files function to attach "uploadUrl" property to each of the file objects.

[ SET_KEY( outputs["Pick files"].files[0], "uploadUrl", "http://uploadurl") ]
