Access layers

To access a feature layer, feature layer view, or table in a feature service, you can use the service URL or item ID. To find this information, you need to go to the hosted layer item page for the dataset in your portal. The method you use to access the layer and features depends on the API you are using and whether or not you need to access the settings stored in the hosted layer (item).

How to access layers

The steps to find and access layers are:

  1. Log in to your portal with your ArcGIS account.
  2. In My Content, find your hosted layer (item).
  3. In the hosted layer item page, find the service URL or item ID.
  4. Use an API to request features:

Data hosting
Process to access features from feature layer in a feature service.

Service URL

To access the layer in the service directly, use the URL and ID for the layer. Accessing the URL directly gives you access to the layer, but does not give you access to the settings configured in the hosted layer (item) such as the visualization and styles, data field filters, and popup settings. Using this method you are responsible for requesting and styling features with your API.

const parcelsLayer = new FeatureLayer({
  url: "https://services3.arcgis.com/GVgbJbqm8hXASVYi/ArcGIS/rest/services/Santa_Monica_Public_Parcels/FeatureServer/0",
  renderer: uvRenderer
});

map.add(parcelsLayer);

Item ID

To access the layer and service through an item, use the portal URL and item ID. Using this approach gives you access to all of the settings stored in the hosted layer (item). The benefit to this approach is the ArcGIS Maps SDKs can read properties such as the visualization and styles, data field filters, and popup settings, and apply them automatically when the layer is accessed.
