This UDA will let you create a SharePoint group in your current site.
There are 2 web services that are part of SharePoint that I tend to use a lot. Lists.asmx web service. I still use that quite often. It's not only good for real work, but also for debugging and seeing the current value of fields, or getting a collection lists or items etc. The other web service I am starting to use more is the UserGroups.asmx web service.
Here's the rub. I'm getting tired of :
1. constantly add a Call Web Service action
2. configure the url
3. configure the credentials
4. click on Refresh
5. select the web method
6. fill in all the details
7. enable error handling etc.
So I decided to wrap up my UserGroup web service calls into UDA (User Defined Actions).
For now, I have only made 4 fairly simple UDA's. There's one thing that all these UDA's have in common, and that is, they use a Nintex Workflow Constant named "Admin Credentials". If you want to have a different credential, then feel free to update the UDA's.
Nintex Workflow 2010
SharePoint Server 2010
Once you have these UDA's, you can go to Manage User Defined Actions in Nintex Workflow 2010 and import them in. Make sure you have the "Admin Credentials" constant, otherwise this won't work at all.
When you have them imported and published, in the Nintex Workflow designer, you'll see this:
