Nintex Workflow for Office 365 is lacking the "Create List" action. I am attempting to use the REST API to do this. The HTTP Web Request action does not have a username and password option, so I am using the regular Web Request action. I am having bad luck getting Some parameters failed the validation check. - [InputWebRequestUrl] : URL is invalid. no matter what I try for the web service URL. I am wondering if anyone has done this and has any tips or examples?
