Is there a way to create a SharePoint group on O365 from the Nintex Workflow Cloud?
I have tried using the "Call a web service" action to call SharePoint REST API for "Users, Groups and Roles" and make a POST request to the URL. However no groups are being created.
Creating a SharePoint group requires minimum Full Control or Owner access on the site, does the account you are using have that permission?
And have you tried capturing "Response Content" and "Response Code" of "Call a Web Service" action? If so, what it says?
