Edit feature data

Add, update, and delete data in a hosted feature layer.

Prerequisites

You need an ArcGIS Location Platform or ArcGIS Online account.

Steps

Create a new pen

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

Get an access token

You need an access token with the correct privileges to access the resources used in this tutorial.

  1. Go to the Create an API key tutorial and create an API key with the following privilege(s):

    • Privileges:
    • Item access
      • Note: If you are using your own custom data layer for this tutorial, you need to grant the API key credentials access to the layer item. Learn more in Item access privileges.
  2. Copy the API key access token to your clipboard when prompted.

  3. In CodePen, update the accessToken variable to use your access token.

    const accessToken = "YOUR_ACCESS_TOKEN";
    
    const authentication = arcgisRest.ApiKeyManager.fromKey(accessToken);

To learn about the other types of authentication available, go to Types of authentication.

Make the request

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

  1. Reference the ArcGIS REST JS libraries either through CDN, ES Modules, or Node JS.

    1. Set the accessToken with an API key access token from API key credentials.
  2. Define the parameters needed for the request.

  3. Call the feature service and handle the results.
