I was working on with the "Get" method in Acumatica API, I successfully pull the records from the API however there is no userID of the creator and modifier.

I tried to find the createdBy and ModifiedBy in the dropdown, but there is none.
How to add the UserID of creator and modifier on the web service endpoint so that these fields will be parts of the Get response?
You can't select these fields with the dropdown, however you can type the fields name in the grid.
