About the ArcGIS Portal Directory

The ArcGIS Portal Directory is an interactive view of the ArcGIS REST API's resources for working with the portal. Use a URL similar to the format https://webadaptor.domain.com/arcgis/sharing/rest to open the Portal Directory. You can browse the capabilities of the portal through the Portal Directory, and if you log in you can further interact with the portal and execute operations. This can be useful for development purposes when attempting to learn the resources and parameters in the REST API.
