Anyone have a suggestion for a way to use workflow to create a document library?
I don’t know of any guides that put it all together in one place. I have a blog post on this site that covers using Call HTTP Web Service to get user profile properties. Here’s another post that may help with that. You would need to adapt the sample screenshots to do a POST to _api/web/lists URL instead. You’ll want to consult this site to learn more about SharePoint’s REST endpoint.
Thanks Paul, you know of any guides out there which might help me to do this?
With a 2013 workflow, you can use the Call HTTP Web Service action to connect to SP’s REST endpoint. Using REST, you can add a document library. You will need to give the workflow app principal increased permissions to allow this, too.
