Nintex SharePoint Online Create SharePoint Group with Contribute permissions

Nintex Workflow has actions “Web Request” and “Call HTTP Web Service” which can be used to make calls to the REST API of SharePoint Online/2013 to automate creation of SharePoint groups in a site collection.

Add the following steps to the workflow

1. Create a Text variable GroupName and Use “Set Workflow Variable” to assign it to a value.
2. Get request digest from targeted site collection. Please note that workflow app permissions need to amended to give site collection full control access.

   • Add “Get Item from Collection” action.
     • Set Target Collection to variable strGroupIDCol
