Rainer, there is two pages on UDAs on the community site:

Best Practice for Workflow Design - User Defined Actions

User Defined Actions - Nintex Workflow

let me know if you need any more details.

I´m sorry Pat but the document I´m searching for is another one. It was an step by step instruction to create a UDA. As I recall it was a web Service with the AddPermission method for which was the UDA created for.

It was a perfect example for my customers....

Best regards

Rainer

Hi Adam,

it seems that the document has never been found. But if you´re looking for a good instruction like a Video, look into the following video from the Nintex channel:

User Defined Actions - The Most Powerful-Yet-Overlooked Feature of Nintex Workflow 2010 - YouTube

Hi Rainer Straub‌,

I know this is an old thread, but probably I've found on my computer the pdf you're mentioning so I've uploaded it here:  

Is it the one you were searching for?
