Get layer metadata

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.

Prerequisites

You need an ArcGIS account to access the developer dashboard and create an API key.

Steps

Create a new pen

If you are using the CDN libraries, to get started.

Get an API Key

To access location services, you need an API key or OAuth 2.0 access token. To learn how to create and scope your key, visit the Create an API key tutorial.

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.

Add code to get layer metadata

Copy and paste the code below, following the steps to make a request to the feature service.

Set the apiKey with the API key from your dashboard.
Define the parameters needed for the request.
Call the feature service and handle the results.
