I am working with Nintex workflow 2013 (on-prem) and am trying to create a UDA that I can pass around to folks who are NOT on my site collections. As such, the other users of the UDA will need to pass in their own credentials for a Call web service action (see screenshot below). Is there a way to securely get this done? By the options when creating a parameter, it doers not look like it.
Any input would be much appreciated.
Thanks and Regards,
