Hello

We are planning a few workflows using UDA’s and utilizing the Web Request action to retrieve and update managed metadata fields on SharePoint lists via the SharePoint REST API. 

What is the recommended way to handle credentials? If using a user/password is the recommended way, then is there a way to support credentials management when exporting/importing workflows via PowerShell scripts on multiple site collections? This is for managing deployment for the TEST, QA and PROD environments.

I have managed to create a script that can replace username/password using XSLT, but this only works for nwf files not UDA files, since these are not plain xml files. So how do I unpack/repack these?

Thanks,

Lars Kohsel
