item ID

An item ID is a unique identifier representing a single content item stored, managed, and accessed in the ArcGIS Platform portal, such as a web map, hosted layer, or file. ArcGIS applications and APIs can use the item's URL or item ID to access the item from the ArcGIS Platform portal. The item ID is included in the item page's URL. For example, the web map at https://www.arcgis.com/home/item.html?id=3d355e34cbd3405dbb3f031286f7b39b has an ID of 3d355e34cbd3405dbb3f031286f7b39b.
