Create List Item in Different Site Collection

I am able to create an Item in a different site collection put I don’t understand how to get the ID of the newly created item. I need to update the current list with the ID so I can link the two items together to keep the two items in sync.

Hello,

Please right click on the workflow action and select properties. In the advanced properties you can find ItemId - this is ID of created list item

Thank you for the information but how do you then save that as a workflow variable so you can update the current list with that ID?

In example above ItemId is workflow variable, after execution the workflow action the variable will contain item ID
