Is there a quick easy way to tell if a rest link is coming from an SDE, other than making an edit and checking the layer in the SDE?
Hi @GaryMorris
Yes you can use the REST endpoint of a layerScroll to the Layer Source or Data Source section:
"dataSource": {"type": "table","workspaceId": "MAP","dataSourceName": "SDE.<FeatureClassName>","gdbVersion": "SDE.DEFAULT"}
