Add, update, and delete data in a hosted feature layer.
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.
- 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.
Make the request
Copy and paste the code below, following the steps to make a request to the feature service.
Reference the ArcGIS REST JS libraries either through CDN, ES Modules, or Node JS.
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.
