Access layers

To access a feature layer, feature layer view, or table in a feature serviceA feature service is a data service that provides access to spatial and non-spatial data in feature layers, feature layer views, and tables.Learn more, you can use the service URL or item IDAn item ID is a unique identifier representing a single item stored, managed, and accessed in a portal, such as a web map, hosted layer, or file.Learn more. To find this information, you need to go to the hosted layerA hosted layer is an item in a portal that contains the properties and settings for a hosted data service or a layer in a hosted data service.Learn more item pageAn item page is a web page in ArcGIS Online or the developer dashboard used to access and manage the properties for an item and the content it references such as a web map, hosted layer, or file.Learn more for the dataset in your portalArcGIS portal, also known as a portal, is a website with applications and tools that can be used to create, manage, access, and share geospatial content and data. It supports security and authentication, developer credentials, content and data service management, user and group management, and site administration. A portal can be hosted in Esri's infrastructure or your own infrastructure.Learn more. 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 layerA hosted layer is an item in a portal that contains the properties and settings for a hosted data service or a layer in a hosted data service.Learn more (item).

How to access layers

The steps to find and access layers are:

1. Log in to your portal with your ArcGIS accountAn ArcGIS account is an identity with a user type and set of privileges that can access specific ArcGIS products, tools, APIs, services, and resources. The main account types that can be used for development are an ArcGIS Location Platform account, ArcGIS Online account, and ArcGIS Enterprise account. ArcGIS Location Platform and ArcGIS Online accounts are also associated with a subscription.Learn more.
2. In My Content, find your hosted layerA hosted layer is an item in a portal that contains the properties and settings for a hosted data service or a layer in a hosted data service.Learn more (item).
3. In the hosted layer item pageAn item page is a web page in ArcGIS Online or the developer dashboard used to access and manage the properties for an item and the content it references such as a web map, hosted layer, or file.Learn more, find the service URL or item ID.
4. Use an API to request features:
   • ArcGIS Maps SDKs: Use the item ID or service URL.
   • Open source libraries: Use the service URL.

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 layerA hosted layer is an item in a portal that contains the properties and settings for a hosted data service or a layer in a hosted data service.Learn more (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.

Item ID

To access the layer and service through an item, use the portal URL and item IDAn item ID is a unique identifier representing a single item stored, managed, and accessed in a portal, such as a web map, hosted layer, or file.Learn more. Using this approach gives you access to all of the settings stored in the hosted layerA hosted layer is an item in a portal that contains the properties and settings for a hosted data service or a layer in a hosted data service.Learn more (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.
