I am creating a workflow to create, delete or change SharePoint groups. Within this I got to the point to use the "Call Web Service" action to update the (SharePoint) GroupInfo:
Web method: "UpdateGrupInfo"
In this workflow action I inserted the relevant URL, User credentials and web method.
For the "Web Service Input" fields:
I used the "oldGroupName" as a string (no variable used)
"groupName": also a text was inserted
"ownerIdentifier": no input
"ownerType": no input
"description": no input
I do not know if these 3 fields are required fields to get the right SP Group but I always get an error message after publishing and using this workflow.
Error message after testing via "Run now": "The remote server returned an error: (500) Internal Server Error."
Error message by list item workflow: "Failed to invoke web service. Error returned from server"
Does anyone know how to configure such workflow action to change the Name of a SharePoint Group?
Thanks in advance
