I would like to create or update an item on a list that is in another site collection.
I can see these actions
Call HTTP Web Service and Web Request
Any ideas what the difference is and are there any tutorial or videos on how or use these actions?
Any resources or examples would be appreciated from the Nintex team
1) You can create list items and document sets with 'O365 create list items or document sets action' (screenshot and screenshot2)
2) If you wish to copy or upload documents in a document library use 'O365 upload a file action' (screenshot3 and screenshot4)
3) You can use a combination of create and update list item actions by capturing list item ID into a variable on 'create item action' and then passing it into 'update item' action to update column values
Let me know if you have further questions
