Get local data | ArcGIS REST JS

Learn how to access the ArcGIS GeoEnrichment service.

Get local data using API key authentication

The ArcGIS GeoEnrichment service provides detailed local data for specific countries. Each individual data field is represented by an analysis variable that are organized into data categories such as spending and market behaviors such as 2022 Educational Attainment or 2022 Seen Video Ad at Gas Station Last 30 Days. The data available vary by country and by data provider.

In this tutorial, use ArcGIS REST JS to access the GeoEnrichment service and display spending trend information for a study area within the United States.

Prerequisites

You need an ArcGIS Location Platform or ArcGIS Online account.

Steps

Get the starter app

Select a type of authentication and follow the steps to create a new app.

Choose API key authentication if you:

Want the easiest way to get started.
Want to build public applications that access ArcGIS Location Services and secure items.
Have an ArcGIS Location Platform or ArcGIS Online account.

Choose user authentication if you:

Want to build private applications.
Require application users to sign in with their own ArcGIS account and access resources their behalf.
Have an ArcGIS Online account.

To learn more about both types of authentication, go to Authentication.

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

Set up authentication

Create a new API key credential with the correct privileges to get an access token.

Go to the Create an API key tutorial and create an API key with the following privilege(s):
- Privileges:
  - Location services > Data enrichment
Copy the API key access token to your clipboard when prompted.

Set developer credentials

Use the API key or OAuth developer credentials so your application can access ArcGIS services.

Update the accessToken variable to use your API key.

Use dark colors for code blocks
    const accessToken = "YOUR_ACCESS_TOKEN";

In both the index.html and callback.html files, replace YOUR_CLIENT_ID and YOUR_REDIRECT_URL with the client ID and redirect URL of your OAuth credentials.

index.html
Use dark colors for code blocks
    /* Use for user authentication */
    const clientId = "YOUR_CLIENT_ID"; // Your client ID from OAuth credentials
    const redirectUri = ""YOUR_REDIRECT_URI""; // The redirect URL registered in your OAuth credentials
    const authentication = await arcgisRest.ArcGISIdentityManager.beginOAuth2({
      clientId,
      redirectUri,
      portal: "https://www.arcgis.com/sharing/rest" // Your portal URL
    });

callback.html
Use dark colors for code blocks
    arcgisRest.ArcGISIdentityManager.completeOAuth2({
      clientId: "YOUR_CLIENT_ID", // Your client ID from OAuth credentials
      redirectUri: "YOUR_REDIRECT_URI", // The redirect URL registered in your OAuth credentials
      portal: "https://www.arcgis.com/sharing/rest" // Your portal URL
    });

Run the app and ensure you can sign in successfully.

If you are unable to sign in, make sure you have the correct redirect URL and port. This URL varies based on your application and typically takes the format of https://<server>[:port]/callback.html or http://my-arcgis-app:/auth. For example, if you are running an application on http://127.0.0.1:5500/, set http://127.0.0.1:5500/callback.html as your redirect URL in the index.html and callback.html file and your developer credential. They all have to match!

Make the request

You can copy and paste the code below, following the steps to make a request to the GeoEnrichment service.

Reference the arcgis-rest-request and arcgis-rest-demographics libraries either through CDN, ES Modules, or Node JS.
Define the parameters needed for the request. For local data set the analysisVariables parameter.
Make a request to the GeoEnrichment service and handle the results.

Use dark colors for code blocks
    <script>

    /* Use for API key authentication */

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

    // or

    /* Use for user authentication */
    // const authentication = await arcgisRest.ArcGISIdentityManager.beginOAuth2({
    //   clientId: "YOUR_CLIENT_ID", // Your client ID from OAuth credentials
    //   redirectUri: "YOUR_REDIRECT_URI", // The redirect URL registered in your OAuth credentials
    //   portal: "https://www.arcgis.com/sharing/rest" // Your portal URL
    // })

        authentication: authentication,

          "PsychographicsShopping.MP28067A_B",
          "transportation.X7027_I",
          "entertainment.X9005_I"
        ]
      })
      .then((response) => {
        console.log("Demographics:", response);
        document.getElementById("result").textContent = JSON.stringify(response, null, 2);
      });
