In this tutorial, you access a hosted feature layer and get its properties such as the id, name, type, supported capabilities, drawing information, extent, and fields.
Learn more about hosted feature layers in Data hosting in the Mapping APIs and location services guide.
You need an ArcGIS account to access the developer dashboard and create an API key .
If you are using the CDN libraries, use this pen to get started. To access location services , you need an API key or OAuth 2.0 access token .
Go to your dashboard to get an API key. The API key must be scoped to access the services used in this tutorial. In CodePen , update apiKey to use your key. Copy and paste the code below, following the steps to make a request to the feature service.
