I'm trying to make a HTTP Web service call using SharePoint Designer 2013. The URL I'm using is
https://<site url>/_api/web/lists/getbytitle(My List)/items?$select=id,Created,Author/Id&$expand=Author/Id
However, this returns 0 items. If I use
https://<site url>/_api/web/lists/getbytitle(My List)/items?$select=id,Created
this works fine. But as soon as I add Author, it doesn't return anything. How should the url be like for this work? Thanks.
